CARBON FIBER REINFORCED THERMOPLASTIC RESIN TAPE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a carbon fiber reinforced thermoplastic resin tape, which shows high bending strength of a carbon fiber reinforced thermoplastic resin (CFRTP) molded article using the tape as a material and has a wide flat shape. SOLUTION: The carbon fiber reinforced thermoplastic resin tape is manufactured using an apparatus which is equipped with a molten resin impregnation device 6 internally permitting a carbon fiber 4 to travel to impregnate the same with a molten thermoplastic resin and a downstream side slit nozzle for drawing out the carbon fiber 4 passed through the molten thermoplastic resin to be impregnated with the molten thermoplastic resin and constituted so that a nozzle upper member 20 and a nozzle lower member 26 are attached to the end part on the downstream side of the molten resin impregnation device 6 so as to be spaced apart from each other at a predetermined interval so that the gap between the nozzle upper and lower members 20 and 26 is set to 130μm or below and tape cooling means 64 and 66 are provided on the downstream side of the downstream side slit nozzle 12.
