Abstract

본 발명은 자동차의 도어(door)에 장착되어 충격을 흡수하는 충격흡수부재에 관한 것으로서, 충격에너지를 효과적으로 흡수하여, 충돌시 승원의 안전성이 향상되도록 하기 위해, 0°에 가까운 섬유각도를 가진 섬유강화-고분자 복합재료를 60%이상 사용하고, 외부에 패브릭(fabric)형태의 섬유 혹은 각도가 있는 섬유를 가진 섬유강화-고분자 복합재료를 40%이하 사용하여 제작하거나, 5°에서 25°의 섬유각도를 가진 섬유강화-고분자 복합재료를 사용하여 제작하는 충격흡수부재(10)를 브래킷(20)에 의해 도어 내부에 장착하여, 단위무게당 인장강도와 충격에너지 흡수가 일반 강철에 비해 향상되도록 하는 자동차 도어의 충격흡수 부재이다.The present invention relates to a shock absorbing member mounted on a door of an automobile to absorb shock, and to absorb shock energy effectively, so that the safety of the occupant is improved in the event of a collision, a fiber having a fiber angle close to 0 °. 60% or more of reinforced-polymer composite material and 40% or less of fiber-reinforced-polymer composite materials with fabric or angled fiber on the outside, or 5 ° to 25 ° fiber The shock absorbing member 10 manufactured by using the fiber-reinforced polymer composite material having an angle is mounted inside the door by the bracket 20, so that the tensile strength and impact energy absorption per unit weight can be improved as compared with general steel. It is a shock absorbing member of a car door.
