PROBLEM TO BE SOLVED: To inhibit strain caused by thermal shrinkage of resin after thermoforming while increasing the rigidity of a fiber-reinforced composite material.SOLUTION: A fiber-reinforced composite material includes: first and second fiber materials 11 and 12 having a square shaped outer shape where the acute angle B1 of the angles made by two diagonal lines L1 and L2 is less than 60°, and comprising reinforced fibers R1 and R2 oriented in parallel to the diagonal lines L1 and L2; and a third fiber material 13 comprising third reinforced fibers R3 oriented in parallel to a bisector of the obtuse angle of the angles made by the two diagonal lines L1 and L2. The rigidity of the third fiber material 13 is set higher than that of the first fiber material 11, and also that of the second fiber material 12.

    【課題】繊維強化複合材の剛性を高めつつ熱成形後の樹脂の熱収縮によるひずみを抑制する。【解決手段】2本の対角線L1,L2のなす角のうち小さい方の角B1が60?より小さい四角形状の外形を有し、対角線L1,L2に平行に配向された強化繊維R1,R2からなる第1及び第2繊維材11,12と、対角線L1,L2のなす角のうち大きい方の角の二等分線と平行に配向された第3強化繊維R3からなる第3繊維材13と、を備え、第3繊維材13の剛性が、第1繊維材11の剛性より高く、かつ、第2繊維材12の剛性より高く設定された繊維強化複合材。【選択図】図3
