To provide a structural material having both rigidity and lightness.SOLUTION: The structural material 1 in resin has at least an upper surface configuration part 11 and a lower surface configuration part 12. The structural material 1 comprises unidirectional carbon fiber reinforcement resin sheets 11b and 12b in which the upper surface configuration part 11 and the lower surface configuration part 12 are at 0° ± 20° of orientation direction of a reinforced fiber relative to a longitudinal direction of the structural material. In addition, the structural material 1 may comprise support parts 13 and 14 for connecting the upper surface configuration part 11 and the lower surface configuration part 12 and this support part 13 and 14 may comprise a unidirectional carbon fiber reinforcement resin sheet 13b, 13c, 14b and 14c.SELECTED DRAWING: Figure 1
【課題】剛性と軽さを両立した構造材を提供する。【解決手段】少なくとも上面構成部11及び下面構成部12を有する樹脂製の構造材1であって、この構造材1は上面構成部11及び下面構成部12が強化繊維の配向方向が構造材の長手方向に対して0°±20°以内である一方向性炭素繊維強化樹脂シート11b及び12bを含む。また、構造材1は上面構成部11と下面構成部12とを繋ぐ為の支持部13及び14を有していても良く、この支持部13及び14は一方向性繊維強化樹脂シート13b、13c、14b及び14cを含んでいても良い。【選択図】図1
