[0002] Carbon fiber composite materials have the characteristics of high strength, high stiffness, high fracture toughness, corrosion resistance and high damping. When hot pressing carbon fiber composite materials, the carbon fiber prepreg needs to be placed between the upper and lower molds, the molds are closed and a set pressure is applied. After a period of high temperature and high pressure treatment, the resin is cured and formed, and the carbon fiber product can be removed.

[0003] There are many existing carbon fiber product molding processes, including autoclave, molding, hand lay-up, vacuum infusion, thermoplastic, winding, etc. The main components are carbon fiber filaments woven cloth mixed with resin, with a carbon content of more than 80%. The products have good performance, strong rigidity, corrosion resistance, etc. However, since carbon fiber is woven into cloth, it has poor shaping, and it is difficult or impossible to shape some products with more complex structures, such as some concave and convex structures with excessively large surfaces, which are difficult to shape.
