A method for preparing a silicon carbide film carbon fiber-ceramic friction material, characterized in that the graphitized carbon fiber is subjected to carburizing treatment, and then subjected to a silicon carbide deposition treatment to prepare a silicon carbide film carbon fiber, which is then chopped and mixed with metal silicon powder, The ceramic powder, carbon powder and mixed solution are mixed to make a slurry, the slurry is quickly injected into the filter press mold to maintain pressure and then heated and solidified. The material blank is processed into a silicon carbide film carbon fiber-ceramic friction material. The friction material prepared by the invention has the characteristics of high strength, high toughness, high wear resistance, long service life and the like. |
