Abstract

Carbon Fiber Reinforced Plastic (CFRP) has strong and superb material properties, especially in mechanical and heat-resisting aspects, but the drawback is its high price. In this study, we made a hybrid composite using carbon fiber and basalt fiber, which is expected to attribute to its strong material properties and its financial benefits. We found out that the higher the content of basalt fiber included, the lower the intensity, and carbon's intensity contents of 80% showed the similar intensity level as that of CFRP. Besides it was possible to get a better mechanical properties using the composite that included the mixed fiber, instead of using a composition of separate fibers filed.

탄소섬유 복합재료는 내열성 및 우수한 기계적 특성을 가지고 있는 우수한 재료이지만 가격이 비싼 결점이 있다. 따라서 본 연구에서는 높은 기계적 강도를 가지며, 가격이 비싸지 않은 재료의 개발을 위해 탄소섬유에 현무암 섬유를 첨가하여 하이브리드 복합재료를 제작하였다. 현무암 섬유의 함유 비율이 높아질수록 강도는 감소하였으며, 탄소의 강화재 비율이 80% 정도에서 CFRP와 유사한 강도를 얻을 수 있었다. 또한 섬유 각각을 적층하여 복합재료를 제작하는 것 보다 섬유사를 혼합시켜 제작한 복합재료에서 더 우수한 기계적 특성을 얻을 수 있었다.
