Abstract

본 발명은 특정 방향의 내 충격성, 인장강도 등이 기계적 물성을 유지하면서 그의 직각방향의 기계적물성을 향상시켜 자동차 범퍼빔, 토목, 건축용 등의 구조재에 사용될 수 있는 열가소성 복합재료 프리 프레그를 제조하는 방법에 관한 것이다.
즉, 본 발명은 유리섬유 매트로 유리섬유 로빙을 무배향의 균일한 웨브(web)를 형성하고 그 위에 일방향 및 그의 직각방향으로 유리섬유를 배열한 후 니들펀칭하여 제조된 것을 사용하여 폴리프로필렌수지를 유리섬유 매트에 열용융 함침하여 판상의 열가소성 복합재료 포리프레그를 제조한 것으로서, 본 발명에 의해 제조된 경우 경량이면서 특정 방향으로의 기계적 강도가 우수할 뿐만 아니라 그의 직각방향의 물성도 향상되어 여러가지 용도로 사용 가능한 잇점이 있다.
