Abstract:
A method for producing a fiber-reinforced resin molded article includes disposing a suction medium, a resin barrier aeration medium and a fiber base material in a cavity such that the suction medium is disposed between an end part of the fiber base material and a mold, and the resin barrier aeration medium is disposed between the suction medium and the end part of the fiber base material. The method further includes: impregnating the fiber base material with a resin by injecting the resin from an injection part, while reducing a pressure in the cavity by suction from a suction part; curing the resin with which the fiber base material is impregnated; and releasing a fiber-reinforced resin in which the fiber base material and the resin are integrated.
