PROBLEM TO BE SOLVED: To obtain a panel member which can improve bending rigidity against a load in a wavelength direction of a corrugated plate part, a press die for press molding the panel member, and a method for manufacturing the panel member.SOLUTION: A panel member 20 formed of a fiber-reinforced resin material is provided with a corrugated plate part 22. In the corrugated plate part 22, a lateral wall part 28 is connected to a standing wall part 24 through a bent part 26. The lateral wall part 28 is provided with a general part 28A extending in a wavelength direction of the corrugated plate part 22 (a direction of an arrow W). A plate thickness t1 of the general part 28A of the lateral wall part 28 is set thinner than a plate thickness t2 of the standing wall part 24. The general part 28A does not contain bubbles having a diameter at least larger than that of reinforced fibers. The orientation direction of the reinforced fibers arranged in the general part 28A of the lateral wall part 28 is set in the wavelength direction of the corrugated plate part 22 (the direction of the arrow W).
【課題】波板部の波長方向の荷重に対する曲げ剛性を向上させることができるパネル部材、前記パネル部材のプレス成形用とされたプレス型、及び前記パネル部材の製造方法を得る。【解決手段】繊維強化樹脂材で成形されたパネル部材20は、波板部22を備えている。波板部22は、横壁部28が曲げ部26を介して立壁部24に接続されている。横壁部28は、波板部22の波長方向(矢印W方向)に延びる一般部28Aを備えている。横壁部28の一般部28Aの板厚t1は、立壁部24の板厚t2よりも薄く設定されている。また、一般部28Aは、少なくとも強化繊維よりも大径の気泡を含有していない。横壁部28の一般部28Aに配置された強化繊維の配向方向は、波板部22の波長方向(矢印W方向)に沿う方向に設定されている。【選択図】図3
