PROBLEM TO BE SOLVED: To provide a lightweight composite material structure while suppressing decrease in strength.SOLUTION: In a composite material structure, which is configured as a fiber-reinforced plastic composite material that extends in one direction and has multiple holes 5 formed at intervals in a row in the one direction and which is subjected to a tensile load and/or a compressive load in the one direction, the peripheral region 3a around the holes 5 comprises a first area 10 obtained by bending composite material, which is reinforced using continuous fibers that have been made even in the longitudinal direction, so that the center line of the width W of the composite material weaves between adjacent holes 5 and zigzags in the one direction. The tensile rigidity and/or compressive rigidity in the one direction of the peripheral region 3a around the holes 5 is smaller than the tensile rigidity and/or the compressive rigidity in the one direction of the other regions 3b that surround the peripheral regions 3a.

    【課題】強度低下を抑制しつつ、軽量な複合材構造体を提供することを目的とする。【解決手段】一方向に延在するとともに、複数の孔5が一方向に間隔を空けて並べて形成された繊維強化プラスチック製の複合材とされ、一方向に引張り荷重および/または圧縮荷重が負荷される複合材構造体において、孔5の周縁領域3aは、長手方向に引き揃えられた連続繊維で強化された複合材が前記複合材の幅Wの中心線が隣合う孔5と孔5との間をぬうように屈曲し一方向に向かって蛇行してなる第1エリア10を含み、孔5の周縁領域3aの一方向における引張り剛性および/または圧縮剛性が、該周縁領域3aを取り囲む他領域3bの一方向における引張り剛性および/または圧縮剛性よりも小さい。【選択図】図5
