LONG FIBER REINFORCED PLASTIC INJECTION-MOLDED PRODUCT

摘要

PURPOSE:To reinforce the part weak in mechanical strength of a long fiber reinforced plastic injection molded product by controlling the flow direction of a long fiber at the time of injection molding. CONSTITUTION:A reinforcing means 32 composed of the constricted part 34 of a molded resin layer obtained by forming a corrugated groove 33 at the time of injection molding and reinforcing a mechanically weak part by disturbing the orientation direction 6 of a long fiber is provided to the mechanically weak part of a long fiber reinforced plastic injection molded product 31 obtained by the injection molding of a plastic molding material containing the long fiber as a reinforcing material.
