To provide a novel curved panel member capable of improving tensile rigidity.SOLUTION: A curved panel member 1 includes: a curved panel 2 made of metal; and a reinforcement member 3 composed of a plurality of FRP layers, including continuous fibers, joined to the curved panel 2 and a matrix resin being a thermoplastic resin. Each of the plurality of FRP layers has one fiber direction. At least one layer of the plurality of FRP layers has a fiber direction different from the other layers. When a maximum main curvature direction of the curved panel is defined as a 0° direction and a direction orthogonal to the 0° direction is defined as a 90° direction, and a 0° direction component and a 90° direction component are calculated with regard to a fiber direction of each layer of the reinforcement member 3 joined to the curved panel 2, using a trigonometric function, the 0° direction component is 40% or more of both components in the fiber direction of the continuous fibers contained in the entirety of the plurality of FRP layers.SELECTED DRAWING: Figure 1

    【課題】張り剛性を向上させることが可能な新たな曲面パネル部材を提供する。【解決手段】金属製の曲面パネル2と、曲面パネル2に接合された、連続繊維を含み、マトリックス樹脂が熱可塑性樹脂である、複数のFRPの層からなる補強部材3とを備え、複数のFRPの層の各々はそれぞれ一の繊維方向からなり、複数のFRPの層のうち少なくとも一つの層は他の層とは異なる繊維方向を示し、曲面パネルの最大主曲率方向を0°方向、および0°方向に直交する方向を90°方向と定義し、曲面パネル2に接合されている補強部材3の各層の繊維方向について、三角関数を用いて0°方向成分及び90°方向成分をそれぞれ算出した場合において、複数のFRPの層全体に含まれる連続繊維の繊維方向の両成分のうち0°方向成分が40%以上となる、曲面パネル部材1を構成する。【選択図】図1
