The production mainstream deflection of composite material is at present light quantify with green environmental protection, the applied field of this kind of material is very extensive. What our country own research and development gets applied is light quantify material to basically have: High-powered rolled steel, light qualitative aluminium alloy, high strenth is plastic and makings of a few composite profile, among them composite profile makings basically enhances colophony radical with fiber composite material is given priority to.
Compare with phase of other metal stuff, carbon fiber enhances colophony radical composite material has a series of performance dominant position: 1, density is small, quality is light. Carbon fiber enhances colophony radical composite material density is only 1.6 G/cm3, replace gold to belong to material to be able to let product quality become light character with its. 2, be able to bear or endure fatigue, life is long. Carbon fiber enhances colophony radical 80% what the fatigue intensity of composite material can achieve its Jing Jiang to spend, won't have long metabolic case, safety factor tall, stability is good.
3, be able to bear or endure chemistry is caustic good. Laziness is shown below general alkalescent environment, to organic dissolvent, acerbity, alkaline Dou Youliang's good corrosion resistance. 4, hot coefficient of expansion is small. Below normal temperature condition, carbon fiber enhances colophony radical the coefficient of expansion of composite material is negative worth, in 200 fall to 400 ℃ environment, coefficient of expansion is adjacent at 0, material dimension stability is good. 5, have exceedingly good oscillatory attenuation function, can reduce vibration and noise; Coefficient of friction is adjacent 0, wearability is good, can wear away in order to reduce a part, the cooperating that promotes expensive product is smooth degree. 6, electric thermal conductivity is exceedingly good. Electric result is favorable, resistor rate is 10-3 Ω·cm about; Heat conduction effect is good, not harbour is hot, the coefficient of thermal conductivity below groove can amount to 1000 W/(m·K) .
Carbon fiber enhances colophony radical the main component that composite material is aerospace hi-tech product, it reduced aero tractor dry mass effectively, reducing cost while raise effective load and range, those who make contemporary and large aircraft head pick structural material. Besides, carbon fiber enhances colophony radical composite material still applies Yu Xinneng source extensively to open the much territory such as exploration of hair, space, building, car with superior performance. At present hot solidify means is carbon fiber enhances colophony radical the main solidify means of composite material, the cycle that does not pass square type of this kind of hot solidify loss of long, energy big, production cost is high. But the development as technology of composite material workmanship, emerge in large numbers gave a variety of fast solidify way, wait like electron beam solidify, microwave solidify and laser solidify. Believe the development as science and technology, answer the development that combines material will be more and more extensive.
