Document Type and Number:
Japanese Patent JP6557972
Kind Code:
B2
Abstract:
A production method for a fiber-reinforced plastic, in which a preform made of a reinforcing fiber substrate and having a three-dimensional shape and an inner mold operatable in a lateral direction different from an up-down direction are disposed in a mold cavity formed by an upper mold and a lower mold, and a state in which a plate thickness of the preform has been made greater than the thickness of a molded article to be obtained is brought about, and a matrix resin is injected and impregnated into the preform, and, after that, at least one of the upper mold and the lower mold is operated toward the other and the inner mold is operated in the lateral direction to pressurize the preform, whereby the thickness of the preform is controlled so as to be equal to a predetermined product's thickness, and subsequently the matrix resin is hardened by heating to obtain the molded article, and a production apparatus for a fiber-reinforced plastic for use in the production method.
