To provide a fiber-reinforced composite material frame that suppresses the generation of buckling and improves bending strength.SOLUTION: A fiber-reinforced composite material frame 1 comprises: a compression surface part 2 where a compression stress is generated along a longitudinal direction DL when a bending load to bend the frame 1 in a short direction DS orthogonal to the longitudinal direction DL of the frame 1 is inputted to the frame 1; and a side surface part 3 extending in the short direction DS from a corner part 5 adjacent to a compression surface part 2. The compression surface part 2 comprises longitudinal direction orientation layers 11 on which reinforced fibers 11a are oriented in the longitudinal direction DL. A surface layer part of the side surface part 3 is composed of short direction orientation layers 12 as different direction orientation layers on which reinforced fibers 12a are oriented in a direction different from the longitudinal direction DL.SELECTED DRAWING: Figure 3

    【課題】座屈の発生を抑制して曲げ強度を向上した繊維強化複合材製フレームを提供する。【解決手段】繊維強化複合材製フレーム1は、フレーム1の長手方向DLに直交する短手方向DSに向けてフレーム1を曲げる曲げ荷重が当該フレーム1に対して入力されたときに長手方向DLに沿って圧縮応力が生じる圧縮面部2と、圧縮面部2に隣接する角部5から短手方向DSに延びる側面部3と、を備える。圧縮面部2は、長手方向DLに強化繊維11aが配向された長手方向配向層11を備える。側面部3の表層部は、長手方向DLと異なる方向に強化繊維12aが配向された異方向配向層としての短手方向配向層12で構成されている。【選択図】図3
