Composite material and metal, high polymer, pottery and porcelain calls 4 old stuff. Today, or the standard of composite material industry of the area, already became measure its science and technology and one of marks of economic actual strength. Advanced composite material is the source that safety and national economy have competitive advantage. Here among them, epoxy resin is colophony of admirable reaction solidify sex. Composite material domain increases in fiber in, epoxy resin distinguish oneself. It and high-powered fiber PAN base fiber of carbon fiber, S or E fibre glass, fragrant black silk ribbon, polyethylene fiber, basalt fiber is compound, make the important base material that cannot replace and structural material, apply extensively fill in equipment of aviation of electronic electric power, spaceflight, exercise, building conduit of strong, pressure, chemical industry is anticorrosive wait for 6 domains. Article key is discussed aerospace is advanced the issue that the domestic and international current situation of composite material reachs colophony radical to studying and direction. The buildup that composite material uses place of fiber composite material sees a table quite with all sorts of fiber material function 1. Undertook comparative to the function of a few material. By the watch 1 visible, only fibre glass compared the intensity, quantity that compare a pattern to rise respectively with respect to what compare metallic data 540% with 31% , of carbon fiber rise more remarkable. According to document report, the intensity of theory of single crystal black lead that can reach with key density computation by key is as high as 150GPa. Because the further development latent capacity of this carbon fiber is very tremendous. The near future target of Japanese Dong Li company is to make carbon fiber tensile strength achieves 8.5GPa, model to measure 730GPa. Character of need not buy, carbon fiber will be henceforth the main material of housing of solid rocket motor and spray pipe. The other application that develops carbon fiber composite material is able to develop his skill to full, if the plane reachs system of stop a car of high speed train, civil aircraft,reach bearing of structural member of car composite material, high-powered carbon fiber, wind- driven dynamo equipment of large lamina, athletic sports (like lever of ski, bat, fishing) etc. Drop of cost stage by stage as the amplification of carbon fiber scale of production and production, increasing concrete, new-style warm oneself the application in material of device, new-style electrode and even daily articles for daily use also is sure to expand quickly. Our country is cooperate Beijing Olympic Games, plan to develop new-style CFRP building materials to reach energetically with environmental protection, the high-tech CFRP new market related daily expense consumable. Carbon fiber is material of quantity of a kind of high strenth, high standard, theoretic most organic fiber can be made carbon fiber, use as actually the organic fiber of carbon fiber raw material basically has 3 kinds: Stick glue fiber, bitumen fiber, polyacrylonitrile fiber. The carbon fiber that structural member of motor of rocket of present solid body uses is made by polyacrylonitrile fiber mostly.

Aerospace uses colophony radical composite material covers according to concerning a material, spaceflight is aero every reduce quality 1 kilogram, can make carrier rocket reduces 500 kilogram, and satellitic emissive charge amounts to dollar of a few ten million. The element of high cost, make structural material qualitative light, high-powered appear particularly important. The annulus that uses fiber to twine craft to make engine cover of oxygen radical solid is anti-corrosive, high temperature resistant, anti-radiant, and density is small, rigid tall, dimension stabilizes good, intensity. The material preventing heat that is like missile warhead and satellitic commutate cover, spacecraft again, solar battery blast substrate introduced link oxygen radical reachs annulus oxygen fiber of phenolic aldehyde radical enhances material to make. Stem from spaceflight aviation flight and its safe consideration place to need, as the structure material should have light qualitative excel in, high reliability and stability, composite material of annulus oxygen carbon fiber makes indispensable material. The buildup that composite material uses high-powered annulus oxygen material basically is carbon fiber (CF) and fiber of CF He Fangguan (K-49) or excel in fibre glass (the jumbly fiber of S-GF) . What use base material epoxy resin to occupy dosage of colophony of high-powered composite material about 90% the left and right sides. High-powered composite material shapes craft is used more one-way beforehand lay up of dip makings dry method, autoclave solidify shapes. Composite material applies high-powered annulus oxygen extensively already on all sorts of planes. It is with the United States exemple, 60 time begin 20 centuries application is boracic / composite material makes annulus oxygen cover of plane envelope, operation. Because boracic fiber cost is too expensive, 70 years get lost carbon / annulus oxygen composite material, get rapid development. Can divide roughly for 3 phase. Level applies at getting the component part with not large force, be like of all kinds operate face, helm face, faze flows piece, lid of aileron, mouth, obstruction board, landing gear on structure of grade of port, engine cover. The 2nd phase applies Yu Chengli's old structural member to go up, be like stable range, complete move equal remaining part and advocate wing of structure getting power. The 3rd phase applies at complex structure getting power, wait like box of airframe, ala. Can decrease commonly weigh 20% ～ 30% . At present dosage of the composite material on military plan already amounted to structural heft 25% the left and right sides, 80% what occupy airframe surface to accumulate. Composite material is in high-powered annulus oxygen foreign military plan and the applied example on civilian machine are more. Our country 1978 second carbon - Bo / composite material uses annulus oxygen Yu Jiang - 5 model the intake duct sidewall of the plane. Introduce according to concerning meeting expert, 20 centuries 80 time use C/EP as successfully perpendicular and stable range, helm face, complete move equal remaining part and wing to get force case Duan Bi board advocate structural member. Outside ablation composite material is being removed in space navigation industry, application of high-powered composite material is very wide also. If cone of cabin of trident missile instrument uses C/EP hind to decrease,weigh 25% ～ 30% , the province is versed in 50% the left and right sides. Still use as annulus of bearing of canister of the top bracket on instrument bracket and trident missile, eject, 55 auxiliary structural member such as the eject roller bracket, bracket inside inertial unit and batteries bracket. Because decrease,weigh, make cannon-shot increases 342km. The protection of De Erda rocket is overspread and the Duan Yi between class is made by C/EP. All use C/EP frame of bracket of the antenna on American satellite and aircraft, antenna, solar battery and microwave filter to finalize the design production. International uses C/EP to make aerial support structure and large space construction on Telstar V. Space navigation implement the tall gain antenna of ” of the traveler in “ sky second the envelope of inside and outside of reflector and beehive interlining structure used K-49/EP. Space shuttle makes big port with composite material of Nomex beehive C/EP, wainscot of structure of C/EP end cabin. Aerospace develops the current situation and trend spaceflight domestic and internationally new and high technology is advanced to spaceflight the demand of composite material is higher and higher, make advanced composite material develop to a few direction: ① , high-powered change, include raw material high-powered change and goods is high-powered change. If be used at the carbon fiber of aerospace product,already developed T700, T800 by the T300 that uses generally before a few years even T1000. And general epoxy resin is progressively also better by tenacity, be able to bear or endure epoxy resin of Wen Genggao that add pliable but strong, Shuang Mashu fat and get together acyl inferior amine colophony replace; Also put forward to pledge gently to composite material goods, wear-resisting caustic, anti-corrosive, be able to bear or endure microtherm, high temperature resistant, refuse the demand such as oxidation. ② , low cost is changed, technology of low cost production includes each fields such as raw material, compound craft and quality control. ③ , muti_function change, spaceflight is advanced composite material by structure of simple structure progressively implementation and functional unifinication, namely to muti_function change directional development. Carbon fiber enhances composite material (CFRP) is current one of advanced composite material. It pledges gently with its excel in, high temperature resistant, fight corrode, thermodynamic performance is good wait for a characteristic, use as extensively structural material and high temperature resistant fight ablation material, other fiber enhances composite material to be able to not be likened to. Because epoxy resin is mechanical, heat performance is superior, electric performance is good, be able to bear or endure chemical medium sex, be able to bear or endure it is good to await a gender reach craft sex is admirable wait for an advantage, tens of year the main body that coming is matrix of colophony of composite material of solid rocket motor all the time, predict to will comparative henceforth long inside will still such. The defect of epoxy resin is impulse withstand scathing ability is poor, hear resistance is inferior (<170 ℃ ) , mechanical below environment of damp and hot function drops apparent. These year come the development of epoxy resin experienced → of rigid annulus oxygen flexible the process of oxygen of annulus of tigidity of annulus oxygen → . But those who occupy dominant position is aether of glycerine of shrink of rigid double phenolic A2 epoxy resin all the time. Like American “ trident - trident of 1” , “ - the HBRF-55A recipe that rocket of ” of flying Ma Zun of 2” missile and “ uses is given priority to with E-PON826. Come for years each national capital is in through joining flexible and unit the tenacity that improves epoxy resin, through joining unit of new-style and rigid chain structure or agent of solidify of use fluorene balmy amine increase hear resistance, obtained expectant result respectively. High temperature resistant the resin of sex of new-style heat solid that structural composite material uses points to fragrant heterocycle high polymer commonly, if get together acyl inferior amine, get together benzene sulphone, their hear resistance compares modified annulus oxygen and much more luscious group annulus oxygen is taller, get together among them acyl inferior amine is current hear resistance the good, important breed that already realized industrialized production. Get together acyl inferior the acyl of double Ma Lai in amine inferior amine (BMI) is had already get together acyl inferior amine is high temperature resistant, be able to bear or endure damp and hot, anti-radiant characteristic, have the advantage that is similar to epoxy resin to be machined more easily again. But defect is melting point tall, dissolvability difference, brittleness is big, if HexcelF650 is colophony of mature the 2nd acting BMI. Below very damp circumstance, high successive use temperature is 204.4 ℃ , use HexcelF650 base after the battleplan of missile classics jet-propelled of composite material exceeds sprint of velocity of sound, can bear harsher than anticipation hot environment. If can apply at solid engine housing, to its integral performance rise very advantageous. The solidify temperature that current main problem is BMI (about 300 ℃ ) with solidify intensity of pressure (make an appointment with 1.5MPa) to all be compared tall, make twine model adiabatic layer bears hard inside assorted core model and housing. Colophony of cyanic acid ester (CE) is a kind of when 80 time develop 20 centuries new-style colophony. Main use has: High-powered printed circuit board, fully high-powered wave construction material (if radar is overspread) , aerospace uses composite material of construction of Gao Ren sex. The ester of commercial cyanic acid that early at space navigation domain applying base the R-5254C that composite material is American Narmco company, it is the CE that carbon fiber enhances and other resinous mixture. Subsequently, a few supply CE radical composite material beforehand the company that dip expects, vitrification temperature prep above is joined in CE the condition is not brilliant of 170 ℃ is thermoplastic colophony is like polycarbonate (PC) , get together sulphone (PS) , get together ether sulphone (PES) , make CE keeps admirable be able to bear or endure function of report of interpose of function of damp and hot at the same time, intensity is reduced after concussion (CAI) value achieves 240~320MPa, the PI after its use temperature and modified, BMI comparatives. The melt content viscosity of the ArocyL-10 that produces like Ciba-geigy and RTX366 is dinky, have 0.1Pa·s only, special apply to fiber fast dip legal system beforehand dip makings, there is wide applied perspective in SRM development. Trial-produce of use XU71787-07 of “YLA company ” increases into carbon fiber beforehand dip makings, classics quality is evaluated think to be able to make satellitic antenna. Liquid crystal polymer is thermoplastic in colophony relatively distinctive mix a exceedingly good kind, basically have aromatics at present all polyester and copolymerization ester. They are one kind enhances material oneself, high polymer advocate catenary is by tigidity or Duan Herou of half rigid catenary sexual catenary paragraph cut out through the element design and become, liquid crystal form is submitted in melt condition, in cooling process this kind of orderly sex is withheld, make material acquires exceedingly good mechanical property. Typical brand has Vectra colophony of the United States, ekond colophony. Liquid crystal polymer can shape alone already (the) of solid rocket motor that if the United States manufactured all construction part 1990,all makes by liquid crystal polymer, also can regard the colophony of composite material as matrix. Through noting model, mould pressing, extrusion, or make data of banding, filmy account twine shape engine housing. The development experience that domestic and international spray pipe uses colophony radical to prevent hot material is roughly identical, from glass / oxygen of phenolic aldehyde, tall silicon / phenolic aldehyde arrives carbon / phenolic aldehyde, carbon / get together fragrant base acetylene, arrive to muti_function, low function from single function high-powered, the department experienced resinite to arrive from colophony of phenolic aldehyde colophony, modified phenolic aldehyde high-powered colophony. Be opposite at present get together benzene and Mi Zun, get together Kui mouth evil Lin, get together benzene and Zun, get together benzene and thiazole, get together fragrant base the high-powered resinous application such as acetylene considers to already became heat, it is the way that colophony radical defends hot material to develop. As a result of carbon / phenolic aldehyde composite material has production cycle weak point, production cost the characteristic such as moderate of low, function, it is at present ablation of solid engine spray pipe prevents one of uses extensively data in hot material, basically use on the component with if spray pipe is outspread inferior intensity of paragraph of a kind of be heated shedding; Because its price is low, also use carbon on the line of spray pipe larynx of roll booster of American space shuttle even / phenolic aldehyde material. The carbon of foreign model / phenolic aldehyde material has the name such as FM5055, MX4957A, what use phenolic aldehyde colophony to wait to be synthesized for activator with Ba(OH)2, NH4OH more. Although ester of phenolic aldehyde tree is able to bear or endure ablation sex is admirable, but reappearance is bad, ablation but adumbrative sex is poor. The modified way of model of phenolic aldehyde colophony has copolymerization modified, include to introduce cyanogen radical, boracic element, fragrant link organic silicon, and use modified of colophony of colophony of formaldehyde of 2 benzene aether, fragrant alkyl formaldehyde to wait; If resinous of cyanogen radical phenolic aldehyde heats up oxidation stability to rise apparently, decompose temperature to amount to 440 ℃ , the yield below 1000 ℃ charcoal rate amounts to 68%~70% . Obtain to make phenolic aldehyde cultivates colophony more high-powered, our country broad Scientists and Technologists did much research work in respect of modified of phenolic aldehyde colophony, developed boron to wait for colophony of new-style phenolic aldehyde phenolic aldehyde, molybdenum phenolic aldehyde, high into carbolic phenolic aldehyde in succession. Get together fragrant base acetylene (PAA) is the colophony that replaces phenolic aldehyde colophony one kind to prevent hot material matrix as ablation likely. The aromatics that it is a kind of height cross-linking that contains carbolic element and hydrogenous element only inferior phenyl polymer, by 2 acetylene base benzene is become with benzene acetylene polymerization. Theory is as high as 90% into charcoal rate; Transgression of small element by-product is not had when polymerization; Colophony is bibulous rate is extremely low, it is 0.1%~0.2% only, far under 5%~10% of phenolic aldehyde resinous. The good point with main PAA is vitrification temperature extremely tall, ablation reappearance is good, mechanical function maintains high temperature rate is high. Company of American space navigation uses the composite material test specimen that T300 and PAA make. The tensile strength between room temperature lower level is 5.3MPa, fall when 400 ℃ for 1.4MPa; Standard carbon / phenolic aldehyde (the tensile strength between the room temperature layer that FM5055) makes is 4.2MPa only; 0.3MPa[1] already dropped when 260e. College of industry of our country Hua Dong grain already can preparation gives those who apply at spaceflight domain to be able to bear or endure ablation PAA colophony, colophony is amounted to into carbolic rate 85% . 4 courtyards undertook spaceflight 43 times get together fragrant base the advanced research that acetylene colophony becomes the facet such as carbolic rate, compound technical properties, mechanical function, the experiment makes clear, carbon / get together fragrant base acetylene composite material is led into carbon, be able to bear or endure ablation function far the carbon that excel heretofore already applied / phenolic aldehyde composite material. The place of compose of much benzene loop that the main problem that exists at present is PAA causes matrix sex fragile and PAA and carbolic cloth wellability need brought composite material between the layer mechanical function not beautiful. Carbon fiber composite material because its are taller be in abroad than the intensity, quantity that compare a pattern application of respect of motor of rocket of solid of advanced strategy, tactics is more, missile of intercontinental of solid of motor-driven of new-style Liu Ji one, 2, housing of engine of missile of tactics of land of land of intermediate range of housing of 3 class engine, new generation. If ” of American “ dwarf is small-sized surface-to-surface intercontinental is ballistic missile housing of firebox of 3 class engine by IM-7 carbon fiber / HBRF-55A epoxy resin is twined make, PV/W≥39KM of coefficient of housing container character; Trident (housing of engine of solid of D5) , 2 class uses carbon / annulus oxygen is made, its function relatively Kaifula / annulus oxygen raises missile of ” of patriot of 30%[17 ～ 20];“ to reach its to improve model, its start housing body to begin to use D6AC steel, to / T800 fiber had been used on PAC-30 missile engine / annulus oxygen composite material; in addition, a kind of when be in charge of development by American army new-style freeboard the missile of small-sized kinetic energy in fast missile system (CKEM) , its housing used T1000 carbon fiber / annulus oxygen composite material, make the quality of engine is compared achieve 0.82. 3 class of ” of dwarf of strategic missile “ launch housing system, “ trident ” one, 2, the composite material skirt of housing of 3 class engine, the spray pipe of commando series engine is outspread paragraph, partial solid engine reachs missile of high speed tactics, for example American THAAD, ERINT. From 20 centuries 60 time end begins, mix with S Bo fine in spaceflight domain the complete metal pressure vessel that liner of metal of Kevlar-49 fiber compound pledges pressure vessel replaces a tradition gradually gently. The United States began to pledge composite material gas cylinder is reached gently 1975 store box development, use S- Bo a rope for towing a boat / oxygen of colophony of linear phenolic aldehyde of BADCy/E-51/ of annulus of annulus oxygen, Kevlar/ twines composite material. Rise as carbon fiber function reach cost to drop substantially, carbon fiber and low cost aluminous liner make technical photograph tie, make fare low, quality the production of the high-pressured container with tall, good dependability makes light, property reality. Express the carbon fiber of 2 liner of two kinds of metals that are production of American SCI(Structural Composites Industries) to twine pressure vessel material and function to compare a situation. By the watch 2 see, at present the space basically uses epoxy resin with composite material matrix. In addition, abroad replaces a metal to make dimensional aircraft with composite material (station of satellite, space, space shuttle) the application that component part already obtained certain level at present. Express 3 it is foreign composite material the circumstance of a few application on dimensional aircraft [18~20] . Wait for the advantage of the respect as a result of the density of carbon fiber, hear resistance, tigidity, enhance fiber to be given priority to with carbon fiber. The application of carbon fiber composite material on dimensional technique, home also has successful model, used carbon fiber like a practical telecommunication satellite of our country / annulus oxygen system of antenna of composite material paraboloid; Meteorological satellite of a ” used wind and cloud-a stormy or unstable situation of “ of sun synchronism orbit solar cell of tigidity of composite material of carbon fiber of much fold type blast the structure. As the rapid development of aerospace industry, increasingly slashing also to the requirement of material, the development of a new material and applied level, reflected national defence and scientific research level greatly, accordingly a lot of significant positions that put the development of new material and application in scientific research job. To get used to the requirement with aerospace increasingly slashing domain, general epoxy resin already cannot satisfy a requirement, each national capital is in devote oneself to to develop all sorts of high-powered epoxy resin, in order to facilitate development is the same as high-powered enhance material (wait like fragrant black silk ribbon, carbon fiber) the resinite that matchs is. But summary rises, it is to be below the premise of the craft sex that makes sure epoxy resin is exceedingly good mostly, those who realize epoxy resin is much more luscious change, with improving its the hear resistance of condensate is mixed stick receive a gender. More commonly used have 4, 4‘- 2 amino 2 benzene firedamp amine of 4 shrink glycerine (TGDDM) , in view of performance/price ratio, it may be practical high-powered epoxy resin. It has admirable hear resistance, the high temperature capability when growing and mechanical intensity maintain rate, solidify systole is low, chemistry and radiation stability are good, still can use at high-powered structure adhesive, structural layer pressing plate and be able to bear or endure high-energy radiate material, a lot of scholars are engaged in the research of system of TGDDM annulus oxygen and development work, gained greater success. What be worth to point out particularly is, classics of our country Scientists and Technologists studies for years, developed trade name to be the 3 luscious round epoxy resin of TDE-85, its change formal name for 4, 5- annulus oxygen personal alkyl - 1, 2 formic acid of 2- ester of 2 shrink glycerine, the shrink glycerine with two reaction tall active is contained in its element the oxygen of fat annulus annulus with ester radical and active of a reaction and former very big difference base. This colophony is sex of a kind of craft, hear resistance all very exceedingly good high-powered epoxy resin, the unit such as institute of glass reinforced plastics of northwest industry university, Harbin is the composite material that base material makes with TDE-85 epoxy resin, application is in certain satisfactory result already was achieved on the product that has special need. The advanced colophony that is intensifier with carbon fiber base composite material is aerospace industry in one of important material. The aircraft is decreased remain the crucial problem that will face henceforth again. In addition, right the concealed body that a lot of national defence that include an aircraft inside equip also is the another key problem that need solves. Accordingly, to advanced composite material, ask its are had not only compare the intensity, quantity that compare a pattern and tenacity high, and the requirement has concealed body property, hold structure and functional function concurrently namely. Developing one of keys of advanced composite material is the colophony matrix with development superior integral performance. Research colophony matrix is at present main the target is: The colophony matrix of A, tall tenacity, if intensity is reduced after the concussion of composite material (the colophony matrix of CAl)>300 MPa. The B, colophony matrix that has Gao Toubo rate, its Tan& is made an appointment with 0.3×10-2. The C, colophony matrix that absorbs radar wave. D, heat-resisting the colophony matrix of 300 ℃ above. The E, colophony matrix that applies to the new-style craft such as RTM. Among them, a, B, D and E already developed a success, but our country still has certain difference. C still is blank. Research and the way that develop colophony matrix are with original colophony modified is given priority to, synthesize new breed to pay equal attention to. Epoxy resin because performance is superior, tens of year coming is the principal part that rocket motor housing uses matrix of composite material colophony all the time, predict to will comparative henceforth long inside will still such. These year will ever had experienced rigid annulus oxygen - flexible annulus oxygen - of rigid annulus oxygen understand a process again, but the annulus oxygen mixture that those who occupy dominant position is aether of glycerine of shrink of rigid double phenolic A2 all the time. The inherent weakness of epoxy resin is impulse withstand scathing ability is poor, heat-resisting function is inferior also (be less than 170 ℃ ) , rocket motor flies below high speed, outside face must good heat insulation, heat with defence pneumatic influence, increased the inert quality of engine so. Come for years each national capital improves epoxy resin performance in effort, increase tenacity or hear resistance for example, with improving the performance of engine ceaselessly. A lot of research works show epoxy resin is improved still have very large latent capacity. 80 time promote obdurability of reinstate hear resistance again thermoplastic colophony will add pliable but strong epoxy resin. These are thermoplastic colophony itself has good tenacity, and modular quantity and hear resistance are taller, grain can be formed likewise in joining epoxy resin as flexibilizer dispersive photograph, their affiliation makes the tenacity of epoxy resin gets rising, and the modular amount that does not affect annulus oxygen condensate and hear resistance. But thermoplastic resinous is joined, the viscosity that often causes a system increases, and the effect that adds pliable but strong is followed inside certain limits add a quantity to increase and increase, this brought a lot of difficult problem to application of project of this kind of resinous, especially of housing of motor of such as rocket twine shape craft, but thermoplastic colophony or a kind of annulus oxygen flexibilizer that have an outlook very much. Developed to use hear resistance in recent years tall, mechanical performance is good thermoplastic the project is plastic will add pliable but strong to heat up solid sex colophony, if get together ether sulphone, polycarbonate, get together ether aether ketone and get together acyl inferior amine. The vitrification temperature that dropping a system thereby, intensity and hardness improve the tenacity of tall cross-linking system below the circumstance that waits for an advantage. 80 time the first time the report gets together with Ultem1000a ether acyl inferior amine (the research of PEI) modified epoxy resin. Li Shanjun synthesized the dissolubility with a series of original structures that have good consistence with epoxy resin to get together ether acyl inferior amine PEI. The very exceedingly good result that add pliable but strong was obtained in Epon-828 and system of TGDDM epoxy resin. Material ruptures can raise 5 times, modular quantity and vitrification temperature are maintained changeless. With a few constituent get together ether acyl inferior amine PEI makes meshy and successive appearance and formed “ double successive ” and “ turn instead the photograph structure of ” . Because the photograph structure of this hierarchy of control makes preparation,colophony of matrix of high-powered composite material is mixed the important step of adhesive. On this foundation, began deep novel get together ether acyl inferior amine originallies to heat sexual resinous adds modified of pliable but strong to consider [23~27] . Apply through reacting to polymerization the research of revulsive separate law is mixed, study all sorts of influencing factor of solidify reaction and detached speed, understand the kinetic model that detached place follows, control split phase condition, acquired property of high strenth heat-resisting successfully admirable, the high-powered matrix colophony that can apply to aerospace industry. Liquid crystal polymer (LCP) in what contain unit of many rigid Jie Jing and certain amount is flexible and removed paragraph, its structure characteristic decided its superior performance. It is provided materiality to become the character of fiber shape structure in machining a process by shearing force action, can produce height to enhance action oneself consequently. TLCP adds pliable but strong the mechanism of epoxy resin basically nails anchorage action mechanism for crackle. Original fine existence can prevent a few TLCP crackle develops, raised the tenacity of matrix, and the hear resistance of material and stiffness are basic not loss. As the progress of research, polymer of the hot liquid crystal that send a gender adds pliable but strong epoxy resin serves as a kind of new technology, be sure to produce main effect in project application. Composite material is developing the basic structure material that makes spaceflight aviation industry quickly. High-powered polymer base composite material occupies his in the dosage of aerospace industry 80% of all dosage. Because carbon fiber is had,compare the intensity, quantity that compare a pattern, small hot coefficient of expansion and tall thermal conductivity high to wait for distinctive function, the composite material that increases by its consequently uses as aerospace construction material, reduce serious effect very remarkable, show incomparable tremendous application potential. Carbon fiber enhances colophony radical composite material is used do space shuttle port, mechanical arm and pressure vessel to wait. On rocket and missile composite material decreases use carbon serious effect is very distinct. Accordingly, use carbon fiber composite material to will reduce the inert weight of rocket and missile greatly, reduce already emissive weight can save emissive cost again or carry heavier warhead or increase effective cannon-shot and placement precision. Orbiter develops type solar battery board use carbon more composite material is made. As carbon fiber and matrix colophony function rise ceaselessly, carbon fiber enhances colophony radical of composite material be able to bear or endure sex of damp and hot and rupture outspread rate gets be improved significantly and rising. The application of aboard already by second bear force structure material develops advocate bear force structure material, widened in the plane industry applies mediumly. Material of new-style concealed body is mixed to the plane missile screen or attenuation radar wave or infra-red feature, rise oneself lives and dash forward prevent ability, have crucial effect. In side of data of body of radar wave concealed, outside dividing coating, composite material is causing the attention of people increasingly as material of structural concealed body, basically enhance colophony of hot solid sex for carbon fiber base composite material (be like C/EP, C/PI or C/BMI) and thermoplastic colophony radical composite material (like C/PEEK, c/PPS) , had gotten certain applying at present. Current situation of composite material of domestic big airlines, problem and direction are compared with military plan photograph of course, civilian machine still can use the way that international purchases to make up for the difference on the technology, if extension of aircraft engine, ministry carries equipment, component and data,can use this kind of means. But civilian machine is made in still having a lot of things is to spend money buy what do not come, be like the overall design ability of the plane, especially compositive ability must rely on experiential to accumulate. Be like telex operation again, this is core technology, empty guest already matured quite in this respect, boeing 777 also used telex to manipulate a technology, still be to pass a technology solely a little among them, family of this kind of technology won't sell us, rely on him research and development only. As we have learned, homebred now the T300 plane composite material that turn is in development, be expected to be able to throw batch production before long, enter buccal T300 in order to replace at present. On the workmanship of composite material, factory of a few main aircrafts also is accelerating newer facility. Be like Xi Fei, its apply the big diameter with the main facility original autoclave of plane composite material to be 3.5 meters, prepare to go up now diameter 6 meters autoclave. The minority in manufacturing industry of domestic aviation product can rely on own research and development, introduce, digestive international advanced technique, realize the manufacturing business that product international obtains evidence and sells. Ha Fei share and airbus company are establishing joint-stock production center jointly, manufacturing A350The composite material component of project of plane of XWB wide system, in cutting a plane formally to produce industrial chain. Wear a structural member of composite material airframe to airbus company successful delivery, this action not only indicate share already became a Ha Fei one of airbus company eligible suppliers, important is, in the large aircraft that makes in own research and development, the composite material that breaths out flying share is sure to get more large-scale apply, the composite material of the company is made face a leap, make the development space of the company more vast thereby. Good luck of strategy of aviation manufacturing industry is all-time. Aircraft manufacturing industry is huge systematic project, it is the result that background science and manufacturing industry enterprise give full cooperation, breath out flying share to have the armament that divides military plan to add the more complete business chain beyond outfit and test-fly. A few years of production army, civil helicopter, light-duty reach branch line to secure alar plane development, certain technology has been done to lay in in participating in production of product of international aerial subcontract to participate in big airlines project for the company. Mix except production the sale is straight 9 series, HC120, EC120 airframe, carry 12 outside waiting for a product, the way that additionally 3 long-term unit of investment involve is the development production of plane of civil branch line and plane of medium-sized civil aviaton, install main production of rich power company to sell plane of branch line of ERJ145 of fan of 50 class eddy among them, this type uses contemporary and advanced turbine fan engine and compositive turn aviation electron equipment, its security, index of comfortable sex and each function no less than large and trunk planes, at present sale of this series aircraft already exceeded 700, what signed large sheet to produce the task to be discharged 2006 2010. The company makes helicopter and medium-sized aircraft in former some (plane of ERJ145 branch line) acquires technical reserve and experience are the advantage is had more when making the company is participating in big airlines project. Technical issue is the main problem of air bus of our country development all the time. Although a little crucial technology was obtained,break through in recent years, but of air bus overall development capacity and advanced level photograph are compared still is all-around difference, especially Boeing, empty customer's new model is massive after using composite material, the development capacity of air bus pulled open a distance with advanced level again. Reserve of civilian machine technology is few. As a result of historical reason, machine of our country civilian is thrown on the technology very little, the technical reserve of civilian machine is fewer. Pan Jiwu of secretary of Party committee of group of former Shanghai Airline says, especially the civilian machine of our country is on practice backwater after a lot of years, the parameter that the plane designs, calm value is accumulated few, ability of civilian machine design is relative weaker, on the technology the breakthrough needs to cost a lot of force. Xi'an aircraft industry (group) finite liability company (abbreviation Xi Fei) , 3 Ceng Gong finished academy of aircraft design academy, flight experiment design together a data, made a detailed assessment to the development capacity of plane of the our country at the beginning of this century. This data says, our country plane designs level and ratio of international level photograph to be apart from about 20 years. Nobody are reached to drive than the technology in technology of technology of supersonic speed cruise, spray pipe vector, tall hold in esteem the respect such as control technology has certain difference, integrated design capacity is small also, design practice experience is defective, the design is normative and backward. Technical field is created in the plane, with the plane production treatment base differs 10 to 20 years, if numerical control efficiency has the 1/8 of Boeing only. More those who let person angst is, as in recent years a large number of application of composite material aboard, the ability that machine of our country civilian develops has the risk that pulls open with advanced level further. The composite material on the plane basically is the composite material that points to carbon fiber. The data that the air bus on international uses previously is give priority to with advanced aluminium alloy, the design of the plane, make build go up in base of this kind of data. With Boeing 777 for exemple, in its airframe structure, aluminium alloy is occupied 70% , steel 11% , titanium 7% , composite material is occupied only 11% , and composite material basically is used at the plane complementary. But to Boeing 787 when, the use of composite material appeared to leap character, not only quantitative increase sharply, and those who begin to be used at the plane is main get power, the composite material dosage of 787 already occupied Boeing now 50% of structural heft. Plane structural member is large-scale use composite material, it is modern plane is made history when go up revolutionary change. It makes plane weight lighter, intensity is higher, be able to bear or endure fatigue corrosion resistance is better, and after the high strenth carbon fiber in composite material undertakes large-scale industrialization is produced, can make the production cost of the plane lower. Below the support that waits for advanced science and technology in scanning of computer technology, laser, C at the same time, the quality of structural member of composite material production plane can the security that more reliable ground assures a plane. According to Boeing and empty guest public research data makes clear, to 2020 their plane will use composite material entirely. And the development capacity that our country masters metallic plane only at present, composite material can a few ground are used in the plane complementary on, in advocate the application on the structure still needs to grind beforehand further. This is just like is empty guest, Boeing can have built a house with reinforced concrete, and the covers with tiles with “ Qin Zhuanhan ” builds a house method that our country masters complete set only, just begin to learning to use reinforced concrete now. Awfuller is, the composite material our country that is used at the plane still needs an import now, the our country of plane composite material that uses so extensively like T800 especially still won't be produced. Our country has the development of air bus, the technical difficulty that face is tremendous. On intense with each passing day aviation market, the banner without the technology, plane that has competition ability, although production came out, also cannot hold the market. Below the big setting that replaces metallic aircraft with composite material plane in Boeing and empty guest, our country should manufacture air bus, have try hard to catch up only, production gives the plane that contends to it to just go, this needs broad technology personnel to give more effort. At present aircraft expert of home cognizant arrived this problem, the plane has before approving an expert to already was carried grind beforehand. According to science and technology of company of aviation industry group appoint vice director Feng Peide discloses, already on 100 million yuan funds is thrown in grinding beforehand now, include material among them. “ is freezing 3 feet, be not cold ” of a day, technology of machine of our country civilian is all-around the ground is backward Yu Ou is beautiful, because the element of many sided is caused,be, basically have 3 among them: Because the model development frequency of machine of our country civilian is too low,be, cannot gather mass data effectively; 2 because civilian engine production still does not have relevant institute up to now,be, civilian machine is up-to-date had not turned to research to open hairstyle; 3 it is our country science and technology changes productivity standard inferior, compare with posture of Euramerican aviation industry, industry of our country aviation has not become right science and technology to change the subject of productivity, science and technology changes the beautiful mode of productivity system mechanism to had been not formed. Our country begins those who seize plane composite material to grind beforehand now, be helpful for narrowing of course the difference with advanced level. But from long-term in light of, should from go up at all the difference that resolves technology of machine of our country civilian to go up, return so that make from 3 matters that settle technology of machine of our country civilian to lag behind for a long time, the frequency that should increase civilian machine to develop namely, establish the special civilian machine institute, aviation industry fine that establishs science and technology to change productivity system mechanism mode. High-powered colophony matrix and its modified are the responsibility of our colophony industry and obligation. The research and development that has made this field hard and industrialization ability make we consume big country to become real production to consume power from a production.
