Abstract

본 발명은 자동차부품, 토목, 건축용등의 거푸집 등에 사용되는 유리섬유가 보강된 열가소성 복합수지의 프리프레그 제조방법에 관한 것으로, 종래의 기술상 문제점인 기계적 강도, 내열성, 함침성을 개선하기 위하여 안출된 것이다. 본 발명은 폴리프로필렌 필름/니들펀칭한 무배향 유리섬유 매트/일렬배열된 유리섬유 얀-폴리프로필렌 필름-일렬배열된 유리 섬유 얀/니들펀칭한 무배향 유리섬유 매트/폴리프로필렌 필름 순으로 적층하여 열가소성 복합수지의 프리프레그를 제조함에 있어서, 폴리프로필렌 필름은 두께가 100-200㎛이고 그 함량이 열가소성 복합수지 총중량의 50-70wt%이며, 니들펀칭한 무배향 유리섬유 매트는 니들펀칭수가 10-20회/㎠, 유리섬유 모노필라멘트의 직경이 15-25㎛인 것을 사용하였으며, 일렬된 유리섬유 얀은 제1도의 장치를 이용하여 유리섬유를 장력을 일정하게 유지시키면서 일렬배향시킬 때 폴리프로필렌 필름을 삽입하여 배향시켜서 제조된 것으로, 총 유리섬유의 함량은 열가소성 복합수지 총중량에 대하여 30-50wt%임을 특징으로 한 열가소성 복합수지의 프리프레그를 제조하는 방법에 관한 것으로서, 종래보다 기계적 성질, 함침성등이 현저히 개선되었다.
