Abstract: A method for molding a laminated body includes laminating a reinforced fiber base material on a molding surface of a molding jig to form a laminated body; attaching a pulling jig to a third lamination portion of the laminated body; forming a protrusive curvature part and a recessed curvature part in the laminated body by curving the laminated body along a protrusive curvature surface and a recessed curvature surface formed on the molding surface while pulling the end of the laminated body with the pulling jig; and densifying the laminated body by heating the curved laminated body while pressurizing the same. The reinforced fiber base material is laminated so that at least a part of a gap between layers of the reinforced fiber base material becomes a non-adhered state in a portion from the protrusive curvature part to the third lamination portion formed in the laminated body.

Abstract: According to one implementation, a molding equipment of a composite material includes a vessel, a decompression system and a heating medium supply system. The vessel houses a molding target sealed by a sealing object. The decompression system performs bending forming of the molding target and pressurization on the molding target after the bending forming by decompressing a region surrounded by the sealing object in the vessel. The heating medium supply system supplies a heating medium into the vessel. The heating medium is supplied for the bending forming, and heating and curing of the molding target under the pressurization.

Abstract: The present invention aims to sufficiently impregnate each layer of a fiber substrate group composed of fiber substrates, which are used for fiber-reinforced resin molding by a resin injection method, with a resin. To successively stack a plurality of fiber substrates, each of which has arrayed fiber bundles and is a material composing a fiber-reinforced resin along with a resin, with their fiber bundles oriented in the same direction, the plurality of fiber substrates are integrated in a state where border zones between the fiber bundles adjacent to each other in an array direction are aligned with one another among the fiber substrates.
