description 본 발명에 따른 자동차용 충돌 에너지 흡수 부품(1)은, 차체의 전방 또는 후방으로부터 충돌 하중이 입력되었을 때에 축 압괴하여 충돌 에너지를 흡수하는 것으로서, 천판부(5a)와 천판부(5a)로부터 코너부(5b)를 개재하여 연속하는 한 쌍의 종벽부(5c)를 갖는 통 형상 부재(3)와, 통 형상 부재(3)의 내면측에 설치되어 적어도 코너부(5b)와의 사이에 폐단면 공간을 형성하는 폐단면 공간 형성 벽 부재(9)와, 폐단면 공간에 형성된 수지(11)를 구비하고, 수지(11)는, 고무 변성 에폭시 수지와 경화제를 포함하고, 인장 파단 신장이 2% 이상 80% 미만에서 계면 박리를 생기게 하는 일 없이 내수성이 우수하고, 통 형상 부재(3) 및 폐단면 공간 형성 벽 부재(9)와의 접착 강도가 12㎫ 이상, 압축 공칭 변형 10%에 있어서의 압축 공칭 응력이 6㎫ 이상이다. An automotive crashworthiness energy absorptive part 1 according to the present invention absorbs crashworthiness energy by crushing axially when a crashworthiness load is input from a front side or a rear side of an automotive body, includes a tubular member 3 having a top portion 5a and a pair of side wall portions 5c continuous from the top portion 5a via corner portions 5b; a closed cross section space forming wall member 9 disposed on an inner surface side of the tubular member 3 and forming a closed cross section space between the closed cross section space forming wall member 9 and at least the corner portion 5b; and a resin 11 provided in the closed cross section space, in which the resin 11 contains a rubber-modified epoxy resin and a hardener, and has a tensile breaking elongation of 2% or more and less than 80%, providing excellent water resistance without generating interfacial peeling, an adhesive strength with the tubular member 3 and the closed cross section space forming wall member 9 of 12 MPa or more, and a compressive nominal stress of 6 MPa or more at a compressive nominal strain of 10%.
