Kind Code:
A1
Abstract:
A method for manufacturing a fiber-reinforced resin molded article from prepreg by press molding comprises: a step of preparing an upper mold and a lower mold, at least one of the upper mold and the lower mold being provided with a resin layer on a surface thereof contacting the prepreg; a step of arranging the prepreg on the lower mold; a step of pressing the prepreg with the upper mold and the lower mold to form the fiber-reinforced resin molded article; a step of separating the upper mold and the lower mold from each other in a state in which the fiber-reinforced resin molded article is sandwiched between the upper mold and the lower mold; and a step of blowing cooling gas to the fiber-reinforced resin molded article and the resin layer to which the fiber-reinforced resin molded article is attached to remove the fiber-reinforced resin molded article from the molds.
