Compared to the traditional metal materials and other fiber made of composite materials, carbon fiber composite material with light weight, high strength, high modulus of elasticity, than the traditional aluminum alloy structure weight loss of 30%, the performance of the weapon and equipment contribution to the upgrading of the huge, is widely used in manufacturing of aircraft body and engine, the missile shell. The F-22, F-35 fighter of the carbon fiber composite proportion reached 24% and 36%, the A350 and Boeing 787 is representative of the new large aircraft carbon fiber composite proportion is reached more than 50%. The application of carbon fiber composites has become one of the symbols to measure the advanced weapons and equipment. Carbon fiber is the key raw material of composite material, and the load of composite material is about 90%. The tensile strength and elastic modulus are the key to achieve the goal of composite structure.

Carbon fiber with tensile strength and elastic modulus as the main indicators, the current commercial products have been developed to the second generation, the two countries in the widely used second generation of carbon fiber products on the performance of the equivalent. The first generation of the 1960s Toray company of T300 and Hexcel AS4 low strength low modulus carbon fiber as the representative of T300 is mainly used for Boeing 737 and other types of bearing components, AS4 used in early F-14 fighter of the tail and other parts. The second generation high strength and medium modulus carbon fiber in the 1980s Toray company T800 and Hexcel Im7 series as the representative, the same generation products and Toray T700, T1000, Hearst IM8, Im9. The strength of T800 is increased by 68% than that of T300, the modulus is increased by 28%, and a large number of main bearing structures for A350, Boeing 787 and so on. Im7 strength than the AS4 was 37% higher modulus increased by 21%, for a large number of American Trident II submarine launched missiles and F-22, F-35 fighter jets and other.
