PURPOSE:To provide a composite material which can be joined by welding or bolting to each other or other metallic member with high strength by coating the entire surface of a fiber-reinforced metal with a matrix metal to be compounded with the reinforcing fibers and a metal of the same type as said metal which is higher in m.p. than said metal. CONSTITUTION:Reinforcing fibers which are carbon fibers, etc. are wound around, for example, an Al cylinder 1 to form the assemblage 2 thereof and another cylinder 3 made of the same Al is put onto said assemblage. A disk 4 made of the same Al is fitted as a bottom plate thereto if necessary. Such superposed body is heated to a desired temp. and is put into a heated die 5. A melt of a matrix metal consisting of an Al alloy which is lower in m.p. than Al is poured into the die 5 and is pressurized by a plunger 7 to impregnate the melt 6 in the assemblage 2 and to cast the assemblage 2 together with the cylinders 1, 3 and the disc 4. A casting 8 including the fiber-reinforced metal 9 is thus obtd. The casting 8 can be welded or bolted without cutting the reinforcing fibers in exactly the same way as for general metallic materials.
