Abstract
To improve the mechanical properties of fiber-reinforced polymer matrix composites, hybrid systems based on unsaturated polyester (UPE) and epoxy (EP) resins with different ratios were investigated and applied to three-dimensional glass fabric-reinforced polymer matrix composites. The effects of hybrid matrix system were evaluated by flexural, tensile, impact, FT-IR and SEM experiments. It was observed that 5 wt% UPE in the hybrid system provided the maximum mechanical properties, particulatly the impact strength. Similar results were found when the hybrid matrix system was applied to the 3D fabric composite. The results from flexure, compression and interlaminar shear strength (ILSS) test were described for the hybrids.

삼차원 직조 유리직물을 보강재로 사용한 섬유강화 복합재료의 기계적 물성을 증진시키기 위하여 에폭시 수지(EP)와 불포화 폴리에스테르 수지(UPE)를 hybrid형 매트릭스로 선정하여 이들의 굴곡, 인장특성 그리고 충격강도를 조사하였고 FT-IR 및 SEM 등을 통하여 결과를 분석하였다. 하이브리드 시스템이 적용된 매트릭스에서 불포화 폴리에스테르의 혼합비가 약 5 wt%일 경우 가장 우수한 물성을 나타내었고 본 매트릭스를 결합재로 사용한 3D 복합재료 시스템에서도 위와 유사한 경향을 나타내었다.
