What is carbon fiber? 

Carbon fiber (abbreviated as CF) is a new type of high-strength, high-modulus fiber that contains more than 95% carbon. 

It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and carbonization and graphitization. Carbon fiber “soft inside and outside” is lighter than metal aluminum, but its strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus.
