PRODUCTION OF FIBER-COMBINED CASTING MEMBER

摘要

PURPOSE:To prevent the decrease in the strength characteristic in the adjacent parts of fibers by combining a composite fiber molding formed by molding one fiber molding and other fiber molding in a way that the fibers are entangled with each other in the adjacent parts to the prescribed position of a casting member by a high pressure solidifying and casting method. CONSTITUTION:A composite fiber molding 20 formed by molding one fiber molding and the other fiber molding in a way that the fibers are entangled with each other in the adjacent parts is manufactured. Such molding 20 is installed in a piston forming mold 21 and a molten Al alloy 29 for casting in a crucible 28 is charged through a sprue 27 into the mold. A plunger 26 is then advanced to cast the molten metal 29 into the mold 21 by a high pressure solidifying and casting method by which a piston blank material embedded with the molding 20 by casting in the head part of the piston is manufactured.
