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: The number of composite material layers laminated to realize a preset thickness of a substrate, for example, a web portion of a panel structural body is referred to as a reference lamination number. Doubler layers that are the composite material layers added to the reference lamination number are laminated in at least a rib base bottom portion of the substrate. Reinforced fibers that includes basic layers and the doubler layers reach a tip portion of the rib. Filler layers that are composite material layers located only at a portion corresponding to a filler region may be laminated in the rib base bottom portion in addition to the doubler layers.

Abstract: A panel structure (10A) includes a substrate portion (11) and at least two ribs (12) standing on the substrate portion (11) and intersecting with each other. A substrate material portion (24) constituting the substrate portion (11) is formed by using at least matrix resin. Continuous fibers or slit continuous fibers are arranged at a position corresponding to the ribs (12) and a rib intersecting portion (13).

Abstract: A connection structure of a light transfer medium includes: a light transfer medium embedded in a structural body; and a protection tube in which the light transfer medium is inserted. The protection tube is embedded in the structural body at one end portion of the structural body. One end portion of the light transfer medium is inserted into the protection tube such that an end of the one end portion of the light transfer medium is positioned inwardly from one end face of the one end portion of said structural body.
