It is made of flaky graphite microcrystal and other organic fibers along the axial direction of the fiber pile, the carbonation and graphitization of the microcrystalline graphite material. Carbon fiber "outside the soft inside just", the quality of aluminum than the light, but the strength is higher than iron and steel, and has a corrosion-resistant, high modulus of the characteristics of the military and civilian aspects of national defense are important materials. It not only has the inherent intrinsic properties of carbon materials, but also both the softness of textile fibers can be processed, is a new generation of reinforcing fibers. Carbon fiber is a carbon material with strong tensile strength and fiber softness and machinability. Carbon fiber is a kind of new material with excellent mechanical properties. The carbon fiber has a tensile strength of about 2 to 7 GPa and a
