A lightweight structure made of a composite material is disclosed. The lightweight structure made of a composite material according to the present invention comprises: a metal upper plate; a metal lower plate arranged at a predetermined interval from the upper plate; and a core layer formed between the upper plate and the lower plate and formed of a non-foaming polymer. The lightweight structure is a plate structural material having a predetermined thickness, and includes a cross-sectional structure in the shape of C-shape including a folded structure in which both ends along the width direction of an entire structure are folded downward. A folded part protruding downward by the folded structure performs the function of a plate reinforcing material. Therefore, there is an advantage of being easy to manufacture, having excellent structural performance, and being able to be manufactured as a long-span structure.

    복합소재로 제작된 경량 구조체가 개시된다. 본 발명에 따른 복합소재로 제작된 경량 구조체는, 금속 재질의 상판; 상판과 소정의 간격을 두고 이격하여 배치되는 금속 재질의 하판; 및 상판과 하판 사이에 형성되며 비발포성 폴리머로 형성되는 코어층을 포함하여 소정의 두께를 가지는 판 구조재로서, 전체 구조의 폭방향을 따른 양단이 하방으로 절곡되는 꺾임구조를 포함하여 'ㄷ'자 형상의 단면구조를 포함하고, 꺾임구조에 의해 하방으로 돌출되는 절곡부가 판보강재의 기능을 수행하는 것을 특징으로 하여, 제작이 간편하면서도 구조성능이 우수하고 장스팬 구조로 제작이 가능한 이점이 있다.
