PURPOSE:To improve the productivity of a fiber reinforced metallic composite material (FRM) by winding continuous fibers or woven fabrics of reinforcing fibers to an assemblage of the long fibers, short fibers, etc. of the reinforcing fibers. CONSTITUTION:The continuous fibers of the reinforcing fibers are passed through a resin bath to stick the resin thereto. Such fibers are cut and the formed long fibers are heated to carbonize the resin. The mixture composed of the short fibers or whiskers of the reinforcing fibers and the resin is otherwise plastically molded in a mold and is then heated to carbonize the resin. The porous assemblage 1 bound with the reinforcing fibers to each other by the carbide is obtd. by the above-mentioned method. The continuous fibers or woven fabrics 2 of the reinforcing fibers are further wound on the assemblage 1 to form a preform material. The preform material is subjected to a high- pressure casting method of a molten metal, by which the need for cutting away the container after the production of the FRM is eliminated and the productivity thereof is improved.
