Embodiment Construction
[0027] The graphitized fiber of the present invention, carbon fiber, ceramic fiber brake disk, take polyacrylonitrile graphitized fiber, polyacrylonitrile carbon fiber, ceramic fiber as skeleton material, nitrile rubber powder and barium sulfate are filler, modified phenolic resin is The binder is mixed to make the brake disc raw material, and then the brake disc is made into the brake disc through hot pressing, heat treatment, surface polishing and drilling; the weight percentage content of each component in the brake disc raw material is:
[0028] Polyacrylonitrile graphitized fiber 0.5%~5%:
[0029] Polyacrylonitrile carbon fiber 45% ~ 65%:
[0030] Ceramic fiber 10% to 25%;
[0031] Modified phenolic resin, with a particle size of 15% to 25% above 1000 mesh;
[0032] Nitrile rubber powder 0.5% to 2%;
[0033] Barium sulfate 0.5% to 2%;
[0034] The manufacturing process of graphitized fiber, carbon fiber and ceramic fiber brake disc is characterized in that it comprise...
