<p>A method for manufacturing a fiber-reinforced resin in which resin is injected into a reinforcing-fiber substrate placed in a molding die from an injection port opened in a direction facing the surface of the reinforcing-fiber substrate, and the resin is then impregnated into the reinforcing-fiber substrate. The fiber-reinforced resin manufacturing method is characterized in that a space for injected-resin transit passage is formed in the reinforcing-fiber substrate in the molding die by at least partially removing in advance a section of the reinforcing-fiber substrate located directly below the injection port in the thickness direction of the reinforcing-fiber substrate, and the resin injected from the injection port is impregnated into the reinforcing-fiber substrate through the space for injected-resin transit passage. By forming, in advance, the space for injected-resin transit passage at the position of the reinforcing-fiber substrate directly below the injection port, the press down of the surface of the reinforcing-fiber substrate due to the injected resin can be suppressed, and by reducing the resin layer on the surface, the design property of the surface of a molded article can be improved while an excellent productivity is maintained.</p> |
