Manufacture of inorganic fiber reinforced metallic composite material

Abstract

Abstract PURPOSE:To manufacture an inorg. fiber reinforced metallic composite material with high mechanical strength by forming Al films having a specified thickness on inorg. fibers, arranging the fibers and a powdered or foil-shaped metal to be combined in a mold, and heating and molding them under pressure. CONSTITUTION:A films having 0.5-10mum thickness are formed on the surface of inorg. fibers. The preferred inorg. fibers are carbon fibers, boron fibers, alumina fibers or silicon carbide fibers having about 5-140mum diameter. The fibers and a powdered or foil-shaped metal to be combined are arranged in a mold, heated and press-molded under pressure. Ti, Ni or an alloy thereof is effectively used as the metal to be combined. The thickness of the foil-shaped metal is about 50-100mum, the particle size of the powdered metal is <= about 40mum, and the molding is carried out at about 800-1,000 deg.C under about 100-1,000kg/cm<2> pressure in about 0.5-6hr to obtain a composite material.
