Abstract

The GFRP composite is used for hot press flow molding of automotive components, and the different flow rates of fiber and plastic are likely to induce fiber orientation and inhomogeneity in the material. However, very limited systematic research studies are available on composite materials with superior flow homogeneity and optimized fiber orientation. The inhomogeneity and fiber orientation issues of GFRP composites have still not been resolved through research. The plain weaving method applied to the GFRP prepreg can improve its recyclability, inhomogeneity, fiber flow, structural stability, fiber deformation, surface smoothness, degree of impregnation, and other mechanical properties. The need for more detailed and thorough studies is evidenced.

유리섬유강화 플라스틱 복합재료의 압축성형 시, 모재와 유리섬유의 분리 없이 유동성이 우수하고, 불균질한 섬유배향이 없는 GFRP 복합재료 개발에 관한 체계적인 연구결과는 미흡한 실정이다. GFRP 복합재료를 사용하여, 자동차 부품 성형 시 발생하는 불균질도와 섬유배향 발생을 억제하는 많은 연구를 해왔으나 아직 해결되고 있지 않다. 본 연구에서는 위의 문제점들을 해결하기 위해 섬유유동성이 뛰어나고, 섬유배향이 발생하지 않고, 불균질성이 없으며, 구조안정성, 함침도, 기계적 특성 및 재활용성 등이 우수한 유리섬유강화 플라스틱 프리프레그를 제조하여, 수직교차형 평직직조방법을 적용하여, GFRP(Glass Fiber Reinforced Plastic) Sheet 를 제조한다.
