Long fiber is thermoplastic plastic (LFT) long-term since use at auto industry all the time, be based on polypropylene especially (PP material is qualitative) product, they have weight light, intensity is mixed high the characteristic that designs freedom, the metal can be replaced in certain structure application.
The development of electric car quickened people to be opposite light quantified interest. Car manufacturer hopes to reduce weight in order to enlarge add boat course of development, because this is reconsidering the material of a few familiar components,choose frame of —— front, scuttle to wait. However, the influence that electric power assembly designs to car also brought new component opportunity.
Sailanisi company (Celanese) one of leaders that are LFT material domain, have Celstran and Compel product line. Develop the version of engineer Olaf Herd according to spot of OEM of Celanese Germany car, stem from light quantify the reason with carbolic footmark, LFT material is applying at the car exterior have latent capacity with in-house component respect.
He expresses, polypropylene (PP) base compound is used at the application related to collision by the consideration normally, be like front, and the structural part such as end door and seat, the machinery of these components and size property must be mixed with good outward appearance, small taste low discharge photograph union. Be based on polyamide (PA, nylon) the component of tall stress function that LFT is considered as to need better hear resistance normally.
In a few projects, cost may be a problem, because must prepare LFT,note model craft and tool to handle the moulding compound that increases highly. In addition, when the consideration uses LFT data, persuade engineering group to use accurate data data to get stuck to also can have difficulty, however, it is very important that this undertakes in the project to ensuring correct imitate and analysis work in the begining.
However, be familiar with the use of LFT material more as OEM and one class supplier, also have hope more.
The function of LFT material also is being improved continuously. High-powered carbon fiber enhanced composite material of PA matrix colophony to had had wide application, but Herd thinks people has fun at in bringing into steel fiber LFT material, in order to provide inherent EMI screen, use natural fine peace keeping to reclaim data will come true can develop a target continuously. Because car interior trim is right TVOC (total volatile organic compound) demand of amiable flavour norms is very high, hind both have quite great opportunity and challenge sex in application of car interior trim.
See an opportunity
The potential opportunity of automobile industry is very charming to Teknor Apex company, the company plans to march LFT domain. This company shows: “ to internal-combustion engine car, the commonnest metal replaces an opportunity is the component below engine lid, and LFT suits not quite normally. Occupy more and more market spaces as electric car, the weight of the car distributinged to also produce tremendous change. This brings about original equipment manufacturer inevitably to put the emphasis on larger part, these components need to raise concussion tenacity and tall tigidity and stiffness. This is the place that LFT produces crucial effect in future. ”
This company will be rolled out later on this year its first LFT product. Teknor Apex company shows: “ standard polypropylene and polyamide base the target of LFT compound is roll out inside this year. Be in before long in the future, we hope to pass can last polymer, part is balmy a group of things with common features polyamide and flame retardant LFT grade, continue to enlarge the combination of product of special type LFT. The cross-linking technology that we still saw LFT grade and our market are banner and 2K shape the interesting opportunity that waits for photograph union. ”
Meanwhile, lie fallow from motion industrial component, main blame car market the demand of the taller, component that can last more is growing lower to lighter, cost, performance. In these application a lot of need more high-powered matrix colophony, the interest that these colophony have specific aim base characteristic, this is Lehmann&The one part that business of Voss company LFT comes to a few years.
We had produced “ LFT is close 30 years. Thomas Collet of chief inspector of sale of ” this company says, “ it only then apply at very special Leakey. The first batch of products that we produce had undertaken modified with lubricant, use at attrition base material. ”
Collet expresses, the company is made had discovered before New Year more, the part that uses LFT to make attrition optimize has quite large dominant position, because of the mechanical strength that its have, fall in high temperature especially, very important to improving performance.
Collet says: “ thenceforth rises, we begin to seek other and special modified data, be like very tall impact resistance. LFT has first-rate anti-impact properties, but we still undertake modified to its, with raising impact resistance ” further. He cited the case that this company extended the handle of nozzle of aviation motor fuel that reveals on the meeting in K last year, long fiber polyamide of the standard still cannot accord with demand of this kind of performance.
Although this is planted,little numerous material is for high-powered and of the design, but this does not mean them is costly alternative certainly. Collet says: “ falls in a lot of circumstances, high-powered mean compare existing performance many a little bit only, but the requirement that won't exceed you. Make plastic the possibility is become in more application —— this is the end that we use composite material, the LFT product to us also is such. ”
The car is traditional polypropylene (PP) base the main application market of LFT, but, lehmann&Voss company does not have a car to regard its as main goal market, although the company also has the product of car LFT respect.
Collet expresses: The function domain that we are interested in “ includes polyamide 12, 66 etc, still biology base material expects. In high-powered polymer the respect still can have more research, these material will smaller numerous, but absorbing. PPA and high temperature polymer are our interest place. ”
Collet thinks, lehmann&The composite material company such as Voss because its dimensions and flexibility, good development place is in in professional LFT domain. In addition, manufacturer of professional composite material still has market knowledge, understanding LFT will be in what respect can bring a change for the client. The diversity aggrandizement of company final user this one insight. “ we applied polyamide on the bicycle 410, bicycle domain is an absorbing LFT market to us. ”Collet listed his to be mixed in industry, sports recreational the application that waits for a variety of markets, on these markets, the company provides data for ski and bicycle component. “ is opposite as consumer carbolic footmark is more and more sensitive, future, composite material makes the everybody of the domain must develop carbolic footmark data, we been doinging this. ”
The metal is replaced
Another obtains evolutional major in LFT material domain compound business is Feddersen group company's subordinate Akro-Plastic company. “LFT compound has superior mechanical performance, because this suits a metal very much,be replaced and light quantify, drop carbolic slot thereby. Whole world of ” this company sells chief inspector to hold Thilo Stier of innovation chief inspector concurrently to say, “ they special accord with market demand. ”
Stier expresses, car, carry and industry is the market that this company is interested in most, decreasing is main driving force again. “ and the identical recipe look that have short staple are compared, extremely high mechanical performance becomes better. For example, energy bumps absorption effect to want tower above two to 3 times. ”
Although LFT remains a kind of costlier than short staple compound material option, but he expresses, huge function promotes and but durative photograph is united in wedlock, can have appeal to a lot of final users. He introduced to be based on biology mainly but can last of second birth polypropylene recipe, and high-powered mix thing in all, the polyamide that is like this company / polypropylene mixes content LFT in all, aim to provide PA performance, drop carbolic slot significantly.
Stier still is in his the IP in LFT regards poor dissimilation as the element. “ the product line that our largest dominant position is as joint as our sister company Feddem development. This makes we can offer product of more extensive special type LFT. At present dominant wears PP/ fibre glass LFT market. And our staple market is nylon, PPA is mixed mixture system. He says ” .
Last year the German K of the end of the year is exhibited on the meeting, akro Plastic revealed to be used at securing the bracket of plant of 2 kilograms of heavy electric car power. This spare parts uses Akromid Lite PA6/PP LFT to shape, increase by the fibre glass of 40% , reduced the weight of 40% than the aluminous component previously, reduced than be based on the LFT level of PA6 8% .
In can develop a field continuously, this company showed the seat base of the motorcycle of KTM FE 350 2022 that makes by Akrolen Next PP LFT. This one material increases by the long fibre glass of 10% , use be based on useless oil residual but production of second birth PP, allegedly carbolic footmark is negative carbon dioxide equivalent.
For what Ziehl Abegg develops fan annulus used 40% glass to increase but second birth PP LFT, secondly oxidation carbon discharge capacity is equivalent to 0.5kg, 1/3 be petrochemical.
Supervisory production
Besides offerring LFT to manufacture a technology to the sororal company Akro-Plastic of Feddersen group, feddem of compound and mechanical manufacturer still provides product line for other and compound company. According to business development director Klaus Hojer expresses, this company sees at present the hope complements or already LFT manufacturer replaces its facility, also potential new participator considers to realize diversity in this domain.
Hojer says, LFTs is satisfying —— of current two crucial demand light quantify and but durative respect still has very long way to want. He says: “ and phase of short staple data are compared, as a result of its intensity rise, LFT compound is noting model in reduce a wall thick, perhaps reduce smaller part through reducing the fiber content in compound, and won't sacrifice intensity. ”
“ considers circular economy, LFT offerred the alternative that uses data again after spare parts service life ends. This is each industries the vast power that from hot solid sex composite material turns to LFT. ” his complement.
Use project is plastic mix with the intensity that replaces fiber to enhance material to be able to enhance LFT material be able to bear or endure lukewarm sex, increase the chance that the metal replaces thereby, the ability that records model mould part at the same time offerred larger part to design freedom to spend, eliminated the need of machining and finish machining.
Producing systematic field, hojer expresses, the main goal of Feddem is to raise automation level, the fiber content that precedes with tall productivity, industry and macerate control, reliable ground makes the LFT material of high quality.
This company decides to handle extruder and roving parallel, what can reduce product line so is overall cover an area of an area. Hoyer says: “ produces 1000 kilograms / the LFT product line of hour compound needs 2.6 meters width only, this makes the level that it accords with short staple to enhance compound composite the dimensional requirement of product line. ”
The IPS intelligence that providing the company that joins key LFT to manufacture a technology recently is Germany makes a solution. Company president Simon Weis expresses, because the demand to final application is higher and higher, growing to the interest of LFT. The limits that “ grows fiber to enhance the metallic substitute with will potential polymer expands new slashing application field. Compare with photograph of their short staple product, LFT can achieve same function, although be below higher temperature. ”
Although IPS is the novice of LFT product line, but it is designed in the system that build bead and develop a respect to having long history, rolled out product line of oneself double screw extruder recently. We received “ a lot of inquiries, to us the interest of the product also is rising. The advantage of IPS depends on service of flexibility, client and custom-built intelligent solution. Our client very admire us can visit gender and quick response time. We can wait for whole system middleman and guarantor to hold this kind of dominant position in stand-alone and IPS-LFT HP system. ”Weis says.
Besides the technology building bead that passes test and verify, its LFT product line still deployed to spread out module, this module passes a design, strict tensional control can be offerred in every winding dot. This makes its can treat a variety of fiber types. Weis predicts, the demand that produces a system to mixing will increase, this system can combine fibre glass and carbon fiber the line is produced in a LFT in, compare an object in order to reach sexual price. IPS-LFT-HP product line still includes module of a macerate, use at handling PP, PA and PPA colophony, need to change only pattern plate can.
Get together ketone radical LFT
Last year the end of the year, avient announces to enlarge range of products of its Complet LFT, include to be based on get together ketone (PK) version. Hopeful of Complet PKE product attracts the client that seeks admirable and mechanical property in harsh cold environment, they can offer PA and POM base the substitute of compound.
Complet PKE series still includes the Edgetek that rolled out 2021™PKE and LubriOne™PKE gets together makings of ketone base material. They are half crystallization, have be able to bear or endure goodly chemical sex, low hygroscopic with as similar as PA66 dimension stability. This grade still provides reductive carbon track: Avient claims the carbolic footmark of PKE is less than PA66 61% , less than PA6 46% .
Eric Wollan of general manager of branch of Avient company PlastiComp says: "This one achievement showed us to be opposite oil natural gas, carry and answer actively of demand of industrial industry client. These clients hope to be material of conduit, canal, fluid management to wait search in low to - the new generation that property still can hold below the circumstance of 22 ℉ project material. We are very glad to can continue to offer new material alternative for our client, help them satisfy specific function requirement and implementation to be able to develop a target continuously. Help them satisfy specific function requirement and implementation to be able to develop a target continuously..
Complet PKE series can provide the different grade data that contains 30%-50% to grow fibre glass, permit a client custom-built function asks to answer certain and special demand.
These products are made in the United States, can supply the whole world. Avient still expanded its are contained last year reclaim product line of resinous Complet REC LFT. The grade that is a foundation with PA6 so was joined now be based on PA66 and TPU base resinous version, after new recipe is used reclaim the level is different —— polyamide 66 (PA66) answer harvest cent to be 25% to 100% , thermoplastic polyurethane (TPU) answer harvest cent to be 25% to 75% .
Wollan expresses, new grade continued Avient is right can last the acceptance of the solution. Their function and be based on PA66 of primitive resinous standard and TPU LFT to comparative, provide black and natural look inside global limits, use fibre glass, carbon fiber enhances a system with mixture fiber.
Polyplastic company of Japan rolled out Plastron LFT series last year, this series increases by fiber of element of recipe regenerated fiber. This company shows, fiber of regenerated fiber element is a kind pledge gently enhance material, because they are to pass proprietary dissolvent wet filature craft regards successive fiber as production, because this suits very much,use at LFT to produce.
This company shows, its test makes clear, enhance PP LFT to have with glass identical the cellulose that curves modular quantity enhanced density of PP LFT resinous to reduce the density that makes an appointment with 5%—40% cellulose to enhance LFT to be 1.06 G/cm3, and equivalent glass LFT is 1.12 G/cm3 (graph 1) . Allegedly cellulose enhances a product to still show better Xia Bichong to attack intensity, tensile strength and flexural strength (graph 2) .
Express 1: Cellulose enhances PP-LFT colophony and coequal fibre glass to enhance the density of grade and the comparison that curve modular quantity.
Express 2: 30% short fibre glass enhance PP and the main function that 40% cellulose fiber enhance PP-LFT to compare.
Hind end box door solution etc
Say according to Borealis, LFTs already applied in door of box of the end after a lot of cars, but what for the masses newest Multivan develops is completely thermoplastic the design is up to now the biggest. This company and accept of Mai Ge of one class supplier (Magna) together, around technology of its Fibremod PP LFT, developed this component for this car manufacturer.
End box door is comprised by a lot of components. Exterior frame and interior spare parts all use the Fibremod GB416LF of Borealis to note model to shape, next agglutinate is together. The exterior spare parts of lacquer also is stuck on end door structure. This component accords with the static state with masses slashing car and dynamic and laden requirement, accord with its to be opposite discharge, case mist is amiable the limitation of flavour.
Fibremod GB416LF is mixed to be used at end door bracket only see structural part and quantity body is custom-built. What this kind of 40% fibre glass increase is low arrange data curve modular quantity to be 8500 MPa, impact strength of summerly comparing breach is 28 KJ/m2, heat is out of shape temperature (HDT) for 160°C, fuse-element flow rate (MFR) for 2g /min (230°C/2.16kg) , density is 1.24 G/cm3. Can satisfy be discharged strictly and mechanical performance demand. Use Fibremod GB416LF still can eliminate extra finishing step, for example spray paint.
In the scuttle framework that develops for contemporary group in Inalfa Roof Systems Korea and GS Caltex Corporation of LFT production business, can see LFT technology is producing another of large part respect new application. This spare parts applies to 2022 models year what the paragraph has Yasuolantuo and contemporary group is a few otherer model, 2022 the automobile body of competition of award of car of North America SPE obtains the first in exterior category.
The is based on PA6 LFT that is used at this component combined two kinds of new technologies. Above all, it used flat fibre glass to increase, according to saying to be able to provide more expensive measure stability is mixed than the tradition but regenerated fiber is 10 times lower warp. Next, the twisting that it used GS Caltex is pulled crowded shape LFT manufactures a technology, realize bigger than length of actual cut grain fiber length according to saying this technology is OK.
Development staff expresses, after changing the part from the metal, weight was reduced 51% , reduce spare parts number 4 from 33. 40% flat glass enhance the warp of the component to be similar to those who have 20% carbon fiber to increase to be based on the LFT of PA6, but cost was reduced 24% .
Last year, company of industry of sand spy base (SABIC) announce, car of east wind of manufacturer of main freight car of company and China cooperates, the car that develops a kind to be used at production to be quantified solid and gently carries kit new-style and compound plastic mixture solution. This application mixed the STAMAX of SABIC™Colophony of polypropylene of long Bo fine and fine of a kind of successive Bo are compound lamination insert, use production of the double lubricious craft that note model. Compare with the photograph of steeliness spare parts of similar design, the weight of finished product spare parts that uses this plan production was reduced 30% , improved the manufacturing efficiency of east wind car effectively.
What mixture production technology will shape beforehand is one-way enhance polypropylene composite tape (surprise by Chinese Jiangsu in this exemple company of one science and technology is produced) in putting a pattern, undertake 2 times shaping with Stamax LFT next. Inserted a crucial area that is a spare parts to increase stiffness and strength, make Bao Bi can be used in the area with lesser stress, reduce weight further thereby.
The photograph of traditional material steel that uses with lorry kit is compared, the plastic composite material of SABIC mixed a solution to expand design option, realized the conformity of the spare parts, avoided to may add 2 operations that big batch of cost and block up produces.
Weight reduced the lorry kit that introduces production of plastic and compound solution about 30% (4-6 kilogram) , still assured to apply needs stiffness, tenacity and intensity at the same time. SABIC ETP and Abdullah Al Otaibi of market solution general manager express: “ passes the data that union differs two kinds, our solution raised product function and machinability significantly. At present technology of this kind of composite material already passed manufacturing test and verify, begin to be produced in volume of east wind car, the application that we hope future has more car field can be benefited among them. ”
Besides lorry kit, the batteries crust that STAMAX colophony mixes the car application with applicable solution to still include module of end door, seat, front and electric car.
