Patent number: 8617336Abstract: This invention provides a method for molding a continuous fiber prepreg part whereby a continuous fiber prepreg part comprising thermoplastic prepreg tape can be molded in a shape that allows the exhibition of desired physical properties without the sacrifice of productivity. Prepreg tape 11 is wound around a plurality of rods 21 so as to form a rolled continuous fiber prepreg part 12, slack is removed from the prepreg tape 11 by shifting the plurality of rods 21 in opposite directions so as to generate tension in the continuous fiber prepreg part 12, the continuous fiber prepreg part 12 is pressed with a press jig 41 so as to mold the prepreg part into the final shape, and the continuous fiber prepreg part 12 is cured by heating and cooling after heating.Type: GrantFiled: January 12, 2011Date of Patent: December 31, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Nobuya Kawamura
