Production of fiber reinforced composite material

Abstract

Abstract PURPOSE: To produce a composite material having dense fiber-reinforced parts easily and efficiently by fixing fiber moldings on the fixing faces formed in the cavities of metallic molds, teeming molten metal into the cavities, filling the molten metal into the fiber moldings under pressure and expelling air. CONSTITUTION: For example, fiber moldings F bundled of unidirectional inorg. fibers are installed on the fixing face 3b of a drag 1b, and a cope 1b is mated with on the drag 1b. The moldings F are sandwiched by the respective fixing faces 3a, 3b and are thereby fixed. Next, for example, molten Al alloy M which is matrix is teemed into the cavities 2a, 2b. Thereafter, the molten metal M is pressurized to be filled and incorporated into the moldings F, whereby the air in the moldings F is expelled from between the respective constituting fibers through air vents S to the outside. Thence, the molten metal M filling the air vents S is immediately solidified. According to this method, a connecting rod C reinforced with fibers in, for example, a rod part C 1 is obtained.
