PRODUCTION OF FIBER REINFORCED METALLIC COMPOSITE MATERIAL

摘要

PURPOSE:To permit easy removal of a titled material from a metallic mold by interposing chloride of a metal between an assemblage of reinforcing fibers and the mold prior to pouring of a molten metal into the mold. CONSTITUTION:The assemblage 2 of the reinforcing fibers is put into a metallic pipe 4 and the pipe is disposed in the metallic mold 1. The powder or granular metal chloride 3 is packed between the mold 1 and the pipe 4. The melt 5 of the metal which is the matrix is poured into the pipe 4 and is pressurized by a plunger 6 by which the molten metal is impregnated into the assemblage 2 and is solidified therein. The solidified metal chloride 3 is eluted by water and a fiber reinforced metallic composite material FRM is taken together with the pipe 4 out of the mold 1 after the molten metal 5 solidifies, i.e., when the FRM is obtd. The pipe 4 is thereafter removed by cutting or stripping and the FRM is taken out. The removal of the FRM from the mold is thereby facilitated and even the long FRM is easily obtd.
