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.

Abstract: A tool system for producing a component from a fiber-reinforced plastic includes a molding tool with a tool surface having a peripheral edge, a compensating body having a coefficient of thermal expansion greater than that of the molding tool, a closure device, and a heating device for heating the molding tool. The tool surface is configured to receive, at a first temperature, at least one ply of a semifinished fiber product having a peripheral contour within the peripheral edge, and of the compensating body, along the peripheral edge, so the compensating body extends from the peripheral edge in a direction of the peripheral contour. The closure device is configured to close the molding tool to form a closed mold and, at a same time, to enclose the at least one ply of the semifinished fiber product and the compensating body. The closed mold includes a resin conduit for receiving resin.

Abstract: A method for injecting an impregnation resin for the manufacture of a revolution part made of composite material in which several clamping blocks are bearing on a fiber texture wound on an impregnation mandrel forming an injection mold for its holding during the cutting of the last layer of the fiber texture in an end-of-winding position, the fiber texture being heated before the removal of the clamping blocks and the closing of the mold to inject the impregnation resin therein.

Abstract: A method for producing a three-dimensional preform from an intermediate preform blank (30, 70), which contain undulations (31) in a portion thereof. The preform blank (30, 79) may be formed on a tool surface (60) containing undulations (61) using an automated placement method such as Automated Tape Laying (ATL) or Automated Fiber Placement (AFP), in which narrow-width strips of material are dispensed side-by-side. Various preform blanks (30, 70) and molding tools (10, 50, 80) have been designed to produce shaped preforms having generally C-shape and Z-shape cross-sections.
