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.The present invention is a method of manufacturing a thermoplastic composite prepreg that can be used in structural materials such as automobile bumper beams, civil engineering, construction by improving the mechanical properties in the perpendicular direction while maintaining the mechanical properties of impact resistance, tensile strength, etc. in a specific direction It is about.

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.That is, the present invention forms a uniform web of glass fiber roving with a glass fiber mat, and arranges the glass fibers in one direction and at right angles thereon, and then uses a polypropylene resin prepared by needle punching. Was manufactured by hot-melt impregnating a glass fiber mat into a plate-like thermoplastic composite polypreg, and when manufactured according to the present invention, it is lightweight and has excellent mechanical strength in a specific direction, and its physical properties in a right direction are also improved. There are advantages that can be used for this purpose.
