PURPOSE: To produce a composite material thoroughly penetrated with a matrix metal into reinforcing fiber materials in the stage of producing a fiber-reinforced composite metallic material by putting the preheated reinforcing fiber materials into a casting mold having an air permeable partition member in the bottom part, pouring a molten metal for the matrix from above the same, vacuum-evacuating the gas from the lower part and pressurizing the materials.
CONSTITUTION: The reinforcing fiber materials 8 such as carbon fibers, alumina fibers or SiC fibers having high strength and high elasticity are preheated and are put into the casting mold 1. The partition member 4 formed of porous ceramics or 150W300 mesh metallic screen is placed in the bottom of the casting mold 1 and is supported from below by a reinforcing plate 5. The melt 9 of the light metal such as Al, Mg or the alloy thereof is poured onto the reinforcing fibers 8 in the casting mold and while the gas in the fibers 8 is sucked and removed from a vacuum discharge port 7, the molten metal 9 is pressurized and solidified by a plunger 10. The light metal which is the matrix metal is thoroughly penetrated into the reinforcing fiber materials 8 and the fiber-reinforced composite metallic material having the excellent reinforcing characteristic by the fiber materials is produced with a good yield.
