MANUFACTURING METHOD FOR FIBER-REINFORCED PLASTIC

PROBLEM TO BE SOLVED: To provide a core-shell type fiber-reinforced plastic that is manufactured by using a plastic prepreg having good fluidity and shaping followability to a complex shape, and exhibits excellence in a physical property, its small variation and dimensional stability. SOLUTION: The manufacturing method of the core-shell type fiber-reinforced plastic comprises the shaping process (1) of mounting a laminate of a plurality of prepreg base materials containing a cut prepreg base material, the molding process (2) of arranging the laminate in a shaping mold, softening a thermosetting resin, injecting a foaming resin, foaming the same, curing the same, at the same time extending the laminate under foaming pressure of the foaming resin and pushing the same to the shaping mold to cure and form the core-shell type fiber-reinforced plastic, and the mold-removing process (3) of taking out the fiber-reinforced plastic from the shaping mold, these processes being conducted in this order.
