PURPOSE:To improve the abrasion resistance at high temperature and the frictional coefficient stability and increase the frictional coefficient by substituting a art of the carbon fiber by the ceramics group fiber, in the frictional member which is prepared by joining carbon fibers by carbon. CONSTITUTION:In order to increase the frictional coefficient of the C/C composite in a frictional member 1, a part of the fiber in the bundle of carbon fiber 2 is substituted by ceramics group fiber 3. Since the ceramics fiber 3 is hard and possesses the polishing action for a friction opponent, the frictional coefficient at low temperature range is improved. When this frictional member is to be prepared, the bundle consisting of carbon fiber and ceramics fiber is impregnated with resin, and said resin is carbonized by heating. Further, the member 1 is impregnated with resin again and heated, and the resin is graphitized, and the ceramic group fiber is left without being combusted. The frictional member 1 thus prepared can be used both in the dried and wet types.
