PRODUCTION OF FIBER REINFORCED COMPOSITE METALLIC MATERIAL

PURPOSE:To obtain a fiber reinforced composite metallic material of a desired shape in which reinforcing fibers are isotropically disposed by housing a fiber assemblage in a compacted state into a case formed of a high melting material and bringing a molten base metal into contact therewith to penetrate said metal into the fiber aggregate then solidifying the material. CONSTITUTION:Carbon fibers 51, etc. are uniformly dispersed and disposed in a metallic mold 1 and an org. binder 52 is poured thereon. A top punch 11 is lowered to compress the mixture and the mixture is hardened by heating to form a compacted molding. such molding is housed in a case formed of a high melting material and is heated to remove the binder 52, by which the fiber assemblage is obtd. The fiber assemblage in the state of being housed in the case is put into the mold 1 and after the assemblage is preheated, the melt of a base metal such as an Al alloy or the like is charged into the mold. The punch 11 is lowered to press the mixture and thereafter the mold 1 is cooled to solidify the molten metal. The fiber reinforced composite metallic material having a high fiber content is obtd. by the above-mentioned method.
