Abstract

Basalt fiber reinforced epoxy composites with fly ash were manufactured and their properties were evaluated. Epoxy resin with fly ash as an additive was impregnated into basalt fibers by hand layup and then manufactured through an autoclave. Although the tensile strength slightly decreased with increasing fly ash content, the flame retardancy test results using a cone calorimeter showed a significant increase in flame retardancy, as indicated by decreased total heat release (THR) and heat release rate (HRR). Basalt fiber reinforced epoxy composites containing 30 wt% or more fly ash exhibited properties suitable for flame-retardant applications.


본 연구에서는 플라이애시를 첨가한 현무암 섬유 강화 에폭시 복합재를 제조하고, 그 기계적 및 난연 특성을 평가하였다. 플라이애시를 포함한 에폭시 수지를 핸드 레이업 공정을 통해 현무암 섬유에 함침시킨 후, 오토클레이브를 이용하여 복합재를 제작하였다. 플라이애시 함량이 증가함에 따라 인장 강도는 소폭 감소하였으나, 콘 칼로리미터를 활용한 난연성 평가 결과, 총 발열량(THR)과 열 방출률(HRR)이 유의미하게 감소하여 난연성이 향상된 것으로 나타났다. 특히, 플라이애시를 30중량% 이상 포함한 복합재는 우수한 난연 특성을 보여 난연성 응용 분야에 적합한 소재로 평가된다.
