Title:
CYLINDRICAL INTERMEDIATE MEMBER FOR MOLDING FIBER REINFORCED THERMOPLASTIC RESIN PIPE, PRODUCTION OF FIBER REINFORCED THERMOPLASTIC RESIN PIPE AND PRODUCING APPARATUS FOR CYLINDRICAL INTERMEDIATE MEMBER
Document Type and Number:
Japanese Patent JP3044360
Kind Code:
B2
Abstract:
PURPOSE: To enhance the productivity of an intermediate member and to achieve the quantity change of a fiber reinforced thermoplastic resin pipe by winding the sheet like fiber reinforced thermoplastic resin impregnated material interposed between a guide member and a mandrel around the mandrel.
CONSTITUTION: A fiber reinforced thermoplastic resin impregnated sheet 23 is arranged on a flexible film or sheet like guide member 22, for example, on the side of a fixed plate 11 and a moving plate 16 is relatively moved with respect to the fixed plate 11 heated by the heater arranged in the fixed plate 11. At this time, the fiber reinforced thermoplastic impregnated sheet 23 is involved in the area between the guide member 22 and a mandrel 13 to produce a cylindrical intermediate member 26. This cylindrical intermediate member 26 is molded in a mold 28 under heating and pressure to produce a fiber reinforced thermoplastic resin pipe 30.
