FORMING METHOD OF BAR-SHAPED FIBER MOLDING FOR FIBER REINFORCED COMPOSITE MEMBER

摘要

PURPOSE:To produce a fiber molding having excellent handling and transporting characteristics with good productivity in the stage of producing the bar-shaped fiber molding for producing a fiber reinforced composite member by impregnating an org. binder in a fiber bundle then heating and drying the bundle and molding the bundle to a bar shape thereby binding the fibers to each other. CONSTITUTION:Fibers, etc. f1-f3 consisting of stainless steel fibers or carbon fibers coated thereon with a metallic film are bundled to one piece by roller 91- 92 in a bundling part 2 to form a fiber bundle Fb. The bundle is passed through the inside of a tank 11 and is impregnated with an org. binder soln. Lb in the tank. Moisture is removed in the 1st heating and drying part 41 and the fibers are tentatively bound to each other by the org. binder. The bundle is fed to a shower part 5 where an org. metallic compd. Lc is injected and impregnated to and in the fiber bundle. The bundle is then heated to remove moisture and is normally bound in the 2nd heating and drying part 42 and thereafter the bundle is molded to a bar shape by a die 15 in a drawing part 6. The bar-shaped bundle is cut to a suitable length by a shearing machine 7 and a bar-shaped fiber molding Fp for reinforcement is produced.
