About high temperature resistant get together acyl inferior amine colophony
Advanced colophony base composite material is pass compound craft preparation to enhance material for matrix, successive fiber with organic high polymer and become, have a kind of of function of apparent excel former constituent new-style stuff. Because this kind of material is had,measure than the model, fight fatigue, anti-corrosive, can design a gender strong, facilitating bedding face accumulates whole to shape reach have special electromagnetism function to wait for a characteristic, after making alloy of afterwards aluminium alloy, titanium and steel one of important aviation construction material.
Get together acyl inferior amine colophony solution
High-powered get together acyl inferior amine pledges gently by right of its, be able to bear or endure high low temperature, be able to bear or endure report of chemical dissolvent, low interpose, flame retardant and superior mechanical performanceWait for integral performance to rank the top of pyramid of high-powered polymer material, its wide application perspective has gotten sufficient recognition, solve the hotshot ” of the problem what can say for “ , itsCan regard special type as the project plastic or colophony of matrix of high temperature composite material. Hot solid sex gets together acyl inferior amine colophony regards advanced composite material as colophony be able to bear or endure in matrix the colophony with lukewarm extremely high order and degree, Use temperature for a long time to exceed 300 ℃ , short-term use temperature exceeds 500 ℃. Because its have excellent hot oxidation stability, mechanical function, interpose report property,reach shape goodly craft sex get all the time the favour of the high-tech domain such as aerospace.

Get together acyl inferior amine colophony and application of its composite material
NASA of 70 time United States developed 20 centuries PMR-15 gets together acyl inferior amine colophony, this colophony suits autoclave to shape craft, Be used extensively at aircraft engine outside the component such as contain path, use temperature for a long time to be 288 ℃ , But existence is able to bear or endure stability of difference of low, tenacity, hot oxidation needs lukewarm order and degree wait for a problem. American NASA and lab of air force material developed the colophony such as PMR-II-50, DMBZ-15, V-CAP, AFR-700B again, composite material be able to bear or endure lukewarm grade raised 371 ℃ , andThe structure that uses engine of missile, aviation successfully to wait and functional sex componentOn, But the shear strength between its layer is low, cost is higher also, restricted its to popularize application.
Go up century 90 time, american NASA and lab of air force material developed benzene the PETI series colophony of acetylene radical Feng Duan, tenacity got promoting considerably, composite material is in the United States cabin of supersonic speed plane paragraph on through test and verify. After entering 21 centuries, In order to contain tigidity asymmetrical 3 structural, 2 anhydride are 4- couplet benzene of the foundation get together acyl inferior the wide attention that amine colophony caused people with temperature of its peculiar low viscosity, tall vitrification and mechanical function. Japanese JAXA developed TriA-PI colophony, its lowest viscosity has 200Pa S only, tg achieved 343 ℃ . American NASA is used 3, 2 anhydride developed 4- couplet benzene to suit RTM craft get together acyl inferior amine colophony PETI-330 and PETI-375, had used at component of aircraft engine passenger compartment and space to go back and forth between type aircraft at present. In the light of PMR model get together acyl inferior there is young member to give off in process of amine colophony solidify, the problem that does not suit big ply large size to make a treatment, Japanese JAXA was developed inferior after amination but dissolve get together acyl inferior amine colophony TriA-X, in aerospace implement good applied prospect was shown on structure and functional sex component.
Get together acyl inferior amine colophony had been formed with 3, 2 anhydride are 4- couplet benzene main monomer, anhydride of benzene acetylene benzene is the data system of the agent that seal end, Development trend of international includes to raise colophony dissolvent sex, reduce colophony fuse-element viscosity, raise material to be able to bear or endure lukewarm grade, raise material tenacity and high temperature to fall to use time for a long time to wait, in order to realize the unity that colophony craft sex is the same as material function.
