PRODUCTION OF FIBER REINFORCED THERMOPLASTIC RESIN MOLDING

摘要

PURPOSE: To easily produce a fiber reinforced thermoplastic resin molding having a desired cross-sectional shape high in specific strength and specific rigidity. CONSTITUTION: A single-layered or double-layered fiber reinforced thermoplastic resin sheet is continuously formed into a hollow member 2 and a thermoplastic resin compsn. 3 is extruded into a hollow shape in a molten state to be applied to the inner surface of the hollow member through the opening part thereof on the way of the formation of the hollow member 2 and the whole is guided to a mold 208 and high pressure air is introduced into the thermoplastic resin compsn. 3 to bring the surface of the hollow member 2 into contact with the inner surface of the mold 208 under pressure to form the hollow member 2 and the thermoplastic resin compsn. 3 into a desired shape.
