Abstract
본 발명은 샌드위치구조물에 관한 것으로, 특히 흡음, 방전 및 단열성이 뛰어날뿐만아니라 고강도, 고강성, 내충격성이 요구되는 곳에 사용하기에 적합한 샌드위치구조체에 관한 것이다. 종래의 허니콤형태의 발포체층은 제작이 어렵고, 무거우며 균열이 전체적으로 일어난다는 단점이 있었다. 본 발명에 따른 샌드위치구조체는 서로 밀도가 다른 발포체층을 갖는다. 본 발명에 따른 샌드위치구조체는 무게에 비해 강도, 내충격성이 뛰어나며, 균열이 발생되더라고 구조물 전체적으로 진행되지 않는다는 장점이 있다. 본 발명에 따른 샌드위치구조체는 고강도, 고강성, 내충격이 요구되는 곳, 특히 특장 차량의 외부 패널이다. 캐빈(cabin)에 사용하면 매우 유용하다.
