C/C composite is a carbon-carbon composite material made of carbon fibers as reinforcement and carbon as matrix through processing and carbonization, with excellent mechanical and high-temperature resistance properties. The material was initially used in aerospace and special fields, and with the maturity of the technology, it has been gradually used in photovoltaic, automotive, lithium battery, medical devices and other fields.

The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.
