PURPOSE:To produce a composite metallic material having excellent performance in the stage of producing the fiber reinforced metallic composite material of a fibrous reinforcing material and a matrix metal, by preheating the reinforcing material to the m.p. of the matrix metal or above then charging the matrix metal under pressure and solidifying the same. CONSTITUTION:A fibrous reinforcing material 10, which is carbon, alumina, silicon carbide, boron or the like, is put into a forming chamber 4 for a composite metallic material while a top mold 2 and a bottom mold 3 are held open. A nozzle 17 inserted into the opening of the upper and lower molds so as to face the forming chamber and a high temp. inert gas such as Ar is blown therein to heat the material 10 and the inside wall of the chamber 4 to the m. p. of the matrix metal to be cast or above. The nozzle 17 is retreated and the molds 2, 3 are securely clamped, whereafter a molten matrix metal 7 is charged into a runner 6 and is forced into the chamber 4 while the metal is held pressurized with a plunger 9. Said metal is solidified in the pessurized state. The composite material adhered uniformly and securely with the material 10 and the matrix metal is obtd. |
