A new type of fibrous material with high strength and high modulus fiber. It is composed of sheet graphite microcrystalline and other organic fibers in the direction of fiber axial direction and obtained by carbonization and graphitization. The quality of carbon fiber is lighter than metal aluminum, but it is stronger than steel, and it has the characteristics of corrosion resistance and high modulus, which are important materials in defense military and civil service. It is not only the intrinsic characteristic of carbon materials, but also the soft and machinability of textile fibers. It is the new generation of fiber reinforced.
Carbon fiber has many excellent properties, carbon fiber axial strength and high modulus, low density, high performance than, no creep, not resistant to ultra high temperature oxidation environment, good fatigue resistance, heat and electrical conductivity between non-metal and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance, permeability good X-ray. Good conductive thermal conductivity and electromagnetic shielding.
The young's modulus is more than three times that of traditional fiberglass. Compared with kevlar fiber, Yang's modulus is about twice as much as that of kevlar, which is insoluble in organic solvents, acids and bases, and is resistant to corrosion.
