To provide a fiber-reinforced resin composite material formed by laminating a plurality of fiber-reinforced resin sheets, capable of suppressing a reduction in strength of a ridge portion.SOLUTION: A fiber-reinforced resin composite material includes: a first laminated body formed of a plurality of fiber-reinforced resin sheets including a unidirectional material; a second laminated body formed of a plurality of fiber reinforced resin sheets including a cloth material, the second laminated body and the first laminated body being connected together in the direction intersecting with the lengthwise direction; and at least a ridge portion along the lengthwise direction. The fibers of the fiber-reinforced resin sheet included in either the first laminated body or the second laminated body are placed so as to intersect the ridge portion. The connection portion between the first laminated body and the second laminated body causes the respective fiber-reinforced resin sheets to alternately overlap with each other in a planar portion continuously provided from the ridge portion. The thickness of the connection portion is changed step by step by displacing the respective ends of the plurality of fiber-reinforced resin sheets of at least either one of the first laminated body or the second laminated body.SELECTED DRAWING: Figure 4
【課題】複数の繊維強化樹脂シートを積層して形成される繊維強化樹脂複合材において、稜線部の強度の低下を抑制可能な繊維強化樹脂複合材を提供する。【解決手段】一方向材を含む複数の繊維強化樹脂シートからなる第1の積層体と、クロス材を含む複数の繊維強化樹脂シートからなる第2の積層体と、が長手方向に交差する方向に繋げられて構成され、長手方向に沿う少なくとも一つの稜線部を有し、第1の積層体又は第2の積層体のいずれかに含まれる繊維強化樹脂シートの繊維が、稜線部に交差するように配置され、第1の積層体と第2の積層体との接続部は、稜線部に連続して設けられた平面部において、それぞれの繊維強化樹脂シートを交互にオーバーラップさせるとともに、第1の積層体又は第2の積層体の少なくとも一方の複数の繊維強化樹脂シートの端部をずらすことにより接続部の厚さを漸次変化させてなる。【選択図】図4
