초록
유리 또는 아라미드 섬유를 보강재로 사용한 섬유강화 복합재료의 기계적 물성을 증진시키기 위하여 복합재료 적층판을 서로 다른 매트릭스 수지와 섬유를 선정하여 이들의 인장, 굴곡 특성을 조사하였다. 불포화 폴리에스테르와 개질된 표면의 아라미드 섬유 복합재료의 경우, 굴곡 물성의 최대값은 실란 농도가 0.5wt%일 때 관찰되었다. 불포화 폴리에스테르 수지와 유리섬유 복합재료의 인장 물성은 vinylester계가 가장 높게 나타났으며, 굴곡물성은 isophthalic계가 가장 높은 물성을 나타내었다. 유리섬유가 불포화 폴리에스테르 수지 복합재료의 기계적 물성을 증진시키기 위해 겹침 적층판과 기계적 물성과의 상관 관계에 대해서도 연구가 병행되었다.
To improve the mechanical properties of fiber-reinforced polymer matrix composites, laminated composites plates were fabricated using different matrix resins and glass or aramid fibers. The effect of matrix resin system were evaluated by tensile, flexural strength measurements. In the case of surface treated aramid fiber and unsaturated polyester resin composite, maximum flexural properties were observed in the composite prepared from the glass fiber treated with 0.5% silane coupling agents. Vinylester resin composites show the highest tensile properties and isophthalic polyester composites have the highest flexural properties among the unsaturated polyester resin composites studied. The relationship between overlap laminated composites plates and mechanical properties of polymer composites is also investigated in order to improve mechanical properties of glass fiber and unsaturated polyester resin composites.
