Title:
CURVED PANEL MEMBER
Document Type and Number:
WIPO Patent Application WO/2021/064870
Kind Code:
A1
Abstract:
This curved panel member comprises a curved metal panel, and a reinforcement member that is joined to the curved panel and that comprises a plurality of FRP layers containing continuous fiber. Each of the plurality of FRP layers has one fiber direction. At least one of the plurality of FRP layers has a fiber direction different to that of the other layers. In the plurality of FRP layers, the proportion of layers in which the angle difference of the fiber direction is 30° or greater is at least 15% of all layers. Relationship (1) is met when, with respect to the respective fiber directions of the FRP layers of the reinforcement member joined to the curved panel, the 0° direction component and the 90° direction component are calculated using a trigonometric function, where 0° is defined as the maximum principle curvature direction of the curved panel and 90° is defined as the direction orthogonal to the 0° direction.
