To provide an impact absorption member for vehicle capable of reducing variation of impact absorption properties.SOLUTION: An impact absorption member 20 has an end surface 41 which receives a collision load. The impact absorption member 20 has; an inside part 50 in which a plurality of fiber reinforced resin layers are deposited to each other, the fiber reinforced resin layers being formed by impregnating the reinforced fibers with a thermoplastic resin, and the plurality of fiber reinforced resin layers are laminated in a lamination direction A. The impact absorption member 20 has two outside parts 60 in which a plurality of fiber reinforced resin layers are deposited to each other, the fiber reinforced resin layers being formed by impregnating the reinforced fibers with the thermoplastic resin, and the plurality of fiber reinforced resin layers are laminated in the lamination direction A. The outside parts 60 hold the inside part 50 from both sides in the lamination direction A. The impact absorption member 20 has two thermoplastic resin layers 80 which are provided between the inside part 50 and each of the outside parts 60, and are respectively deposited to the inside part 50 and the outside parts 60. A direction orthogonal to the end surface 41 and the lamination direction A are orthogonal to each other.SELECTED DRAWING: Figure 1

    【課題】衝撃吸収性のばらつきを低減できる車両用衝撃吸収部材を提供する。【解決手段】衝撃吸収部材20は、衝突荷重を受けるように構成された端面41を有している。衝撃吸収部材20は、強化繊維に熱可塑性の樹脂が含浸されて形成された複数の繊維強化樹脂層が互いに溶着されるとともに積層方向Aに積層されて構成された内側部50を有している。衝撃吸収部材20は、強化繊維に熱可塑性の樹脂が含浸されて形成された複数の繊維強化樹脂層が互いに溶着されるとともに積層方向Aに積層されて構成される2つの外側部60を有している。外側部60は、積層方向Aにおいて内側部50を両側から挟んでいる。衝撃吸収部材20は、内側部50と外側部60の各々との間に位置するとともに、内側部50と外側部60とにそれぞれ溶着される熱可塑性の2つの樹脂層80を有している。端面41に直交する方向と積層方向Aとが直交している。【選択図】図1
