Abstract: A forming device includes: a forming jig extending along an axial direction; a forming die having a shape corresponding to a top part region and a wall part region of the forming jig; and a movement mechanism that moves the forming die so as to approach a bottom part region along a height direction HD. The forming die includes: a body part; a plate-shaped forming part that is attached to the body part so as to be swingable around a swing shaft; and a pressurization part that generates a pressurization force which causes a distal end part of the forming part to push a layered body against the wall part region when the forming die is moved by the movement mechanism so as to approach the bottom part region. In accordance with the distal end part, the part causes a contact surface to contact a region of the layered body.

Abstract: The preset invention is to mold a laminate at a high accuracy by appropriately generating slippage between fiber sheets of the laminate at bending. A method for molding a laminate includes a step in which a plurality of gripping parts, which are arranged apart from each other, grip an area, wherein slippage between fiber sheets is prevented, in a plate-shaped laminate including a plurality of fiber sheets laminated each other; a step in which the plurality of gripping parts grip the area wherein slippage between the fiber sheets is prevented, while maintaining the state wherein relative moving of the area of the laminate and the gripping parts is prevented; and a step in which the gripping parts move so as to subject the laminate to bending.

Abstract: A method includes laminating a plurality of fiber reinforced sheets to create a charge; and shaping, by pressing, the charge created in the lamination step into a shaping mold. The charge has a predetermined angle layer including the plurality of fiber reinforced sheets, the fiber direction of which is aligned in a single direction. The predetermined angle layer has n-number of constitutional layers (n≥2) ranging from a first constitutional layer to an n-th constitutional layer each including the plurality of fiber reinforced sheets, wherein the n-th constitutional layer is laminated on an (n−1)-th constitutional layer, the plurality of fiber reinforced sheets in each of the constitutional layers have dividing portions which are along the fiber direction and which are disposed one by one at respective positions within a predetermined range along the fiber direction in the predetermined angle layer.

Abstract: Provided is a shaping method for shaping a laminated body of multi-layered sheet materials containing reinforcing fibers by using a shaping die. The shaping die has a curved portion formed in a convex shape over a predetermined direction. The shaping method includes: fixing, to the shaping die, a holding member configured to cover the laminated body over the predetermined direction to maintain a state where the laminated body is pressed against the curved portion; sealing the laminated body and the holding member to the shaping die by a sealing member to form a closed space; and depressurizing the closed space to thin the laminated body by sucking air of the closed space, and the fixing fixes the holding member to the shaping die such that the holding member does not come into contact with an end face on one side in the predetermined direction of the laminated body.

Abstract: A composite structure manufacturing method comprising: a lamination step in which a plurality of fiber-reinforced resin sheets are laminated to form a plate-shaped laminate; a pressing deformation step in which a third roller or similar, which rolls along a plate surface of the laminate, is used to press the plate surface of the laminate, thereby forming a recessed section or a protruding section in a prescribed section of the laminate; a short direction deformation step in which, after the pressing deformation step, the laminate is deformed in the short direction to make the long direction cross-section into a prescribed shape; and a long direction deformation step in which, after the pressing deformation step, the laminate is deformed in the long direction to make the short direction cross-section into a prescribed shape.
