MANUFACTURING METHOD OF REINFORCEMENT MATERIAL MADE OF CARBON FIBER-REINFORCED PLASTIC, AND REINFORCEMENT MATERIAL MADE OF CARBON FIBER-REINFORCED PLASTIC

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a reinforcement material made of carbon fiber-reinforced plastic, having a large strength in longitudinal direction.;SOLUTION: Many carbon fibers impregnated with a thermosetting resin are formed into a carbon fiber bundle (CF bundle) 31 having a circular cross section. The CF bundle 31 impregnated with a thermosetting resin, having a circular cross section, is wound with a tape material in a spiral form. The CF bundle 31 wound with the tape material is sent to a pressing apparatus. The CF bundle 31 is heated with a heater 53 and pressed in one direction with a press surface of an endless belt 51 in the pressing apparatus. During pressing, an extra thermosetting resin is discharged from the clearance of the tape material to the outside. The reinforcement material having a rectangular cross section by pressing and a hardened thermosetting resin by heating is rolled up with a rolling up reel.;COPYRIGHT: (C)2014,JPO&INPIT
