[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is made of organic fibers such as flaky graphite microcrystals stacked along the axial direction of the fiber, and is a microcrystalline graphite material obtained through carbonization and graphitization treatment. The carbon fiber winding machine drives the winding drum to rotate through the shaft roller, and the carbon fiber is wound through the winding drum.
