Filed: 1991-12-03
Abstract: PURPOSE:To obtain a friction member comprising a carbon fiber reinforced carbon composite material having improved frictional characteristics in a short time by incorporating baron carbide into the matrix of carbon fiber reinforced carbon composite material. CONSTITUTION:This friction member can be produced by two methods. In the first method, a carrier (e.g. polyacrylonitrile resin deriv. or thermosetting resin modified to be used for electrodeposition) to be ionized in a liquid is made to adsorb on a carbonaceous fine powder and metal boron and/or boron carbide, and then these materials are dispered in a liquid. Then, a carbon fiber base material (e.g. short fibers bundled into strings) is immersed in this liquid and DC voltage is applied between electrodes facing each other to precipitate the carbonaceous fine powder, metal boron and/or boron carbide, and the carrier on the carbon fiber base material. This electrodeposited body is dried, heat molded, heat-treated and calcined for carburization. In the second method, a carbon fiber base material, carbonaceous fine powder, and metal boron and/or boron carbide are mixed, heat molded, heat-treated, and calcined for carburization.
