Abstract

본 발명은 발포수지 의 심재 표면에 섬유보강된 열가소성 수지로 된 멀티레이어 보드를 접합하여 제조되는 복합 성형품 및 그 제조방법에 관한 것이다.
상기의 복합성형품은 원하는 형상으로 성형된 발포수지로 된 심재와 용적함유율로 30%이상, 85% 이하의 강화 섬유를 포함하는 프리그레그를 강화섬유의 방향을 바꾸어 여러매 겹쳐쌓아 그것들에 포함되는 열가소성 수지의 용융온도 이상으로 가열하여 프리프레그를 접착함과 동시에 내부에 포함된 공기를 제거하여 제조된 멀티레이어 보드로 된다.
이 복합 성형품을 제조할 때는 심재의 형상에 적합한 형상으로 성형하여 그 열가소성 수지의 용융온도 이상으로 가열된 멀티레이어 보드를 심재에 압착하여 일체화 한다.
