<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing fiber-reinforced plastic of outstanding quality, while eliminating a level difference and resin reservoir produced at the molding end by difference in the length of profile shape of preform and molding, and excluding trim processing after molding, in a vacuum RTM molding method to manufacture the fiber-reinforced plastic of curved surface shape. <P>SOLUTION: In the method for manufacturing fiber-reinforced plastic, thickness of the fiber-reinforced plastic after resin curing is changed from thickness of preform 2, by: arranging the preform 2 comprising the reinforcement fiber base material on the mold 101 having a curved surface or bending shape; covering the preform 2 with bag materials 3 and carrying out vacuum suction of the core; and filling the resin 10 to the preform 2 and curing the preform 2, the preform 2 is formed beforehand by laminating the reinforcement fiber base materials of different width and/or length, so that the end face of the fiber-reinforced plastic may become a desired shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
