Abstract: A molding device includes: a lower mold that supports a workpiece containing a thermoplastic resin and that is heated to a first predetermined temperature; an upper mold that is opposed to the lower mold, that presses the workpiece, and that is heated to a second predetermined temperature; a transferer that moves the lower mold and the upper mold relative to each other in a transfer direction of the workpiece; and control circuitry. The lower mold includes temperature-controlled regions adjacent to one another in the transfer direction, the temperature-controlled regions including a first lower mold temperature-controlled region and a second lower mold temperature-controlled region having a temperature lower than a temperature of the first lower mold temperature-controlled region. The control circuitry changes proportions of the first and second lower mold temperature-controlled regions in the lower mold as a function of a relative position between the upper and lower molds.

Abstract: A first laminated body is worked to form a second laminated body, the first laminated body being formed by laminating prepregs including reinforcing fibers and resin, the second laminated body including a flat portion and a wavy portion, the flat portion being located at at least one of side edge portions of the second laminated body, the wavy portion being located at a portion adjacent to the side edge portion and extending along a longitudinal direction. An intermediate product is formed from the second laminated body by a forming die such that the flat portion becomes a bent portion that is an inside portion whose circumferential length is shorter in a curved portion, and the wavy portion becomes a bent portion that is an outside portion whose circumferential length is longer in the curved portion.
