초록
무기필러가 첨가된 현무암섬유 강화 에폭시 복합재료를 제조하여 그 특성을 평가하였다. 첨가된 무기필러는 각각 수산화마그네슘, 수산화알루미늄, 알루미나, 베마이트이며 이를 첨가제로한 에폭시 수지를 현무암섬유에 핸드레이업으로 함침시킨 후 hot pressing하여 수지 함침량이 30 wt%인 섬유복합재료를 제조하였다. LOI 평가 결과 BFRP의 LOI (28.9)는 에폭시 수지 (21.4)에 비해 향상된 것을 확인하였으며 무기필러가 첨가될 경우 그보다 더욱 향상되는 것을 확인하였다. 또한 무기필러가 첨가된 복합재료는 무기필러가 첨가되지 않은 복합재료에 비해 콘칼로리미터 시험에서 PHRR, THR, TSR 등이 감소하여 무기필러 첨가에 따른 난연 특성 향상을 확인하였다.
Abstract
Basalt fiber reinforced epoxy composites with inorganic filler (BFRP-F) such as Mg(OH)2 (magnesium hydroxide), Al(OH)3 (aluminum hydroxide), Al2O3 (aluminum oxide) and AlOOH (boehmite) were prepared by hand lay-up and hot pressing. The combustive properties of BFRP-F were improved comparing with basalt fiber reinforced epoxy composite (BFRP) without inorganic filler. At a 30 wt% resin content, the limited oxygen index (LOI) of BFRP is 28.9, which is higher than that of epoxy (21.4), and the LOI of BFRP-F is higher than that of BFRP. The BFRP-F showed the lower peak heat release rate (PHRR), total heat release (THR) and total smoke release rate (TSR) than those of BFRP. We confirmed that the flame retardant properties of the composite were improved by the addition of inorganic filler through the dehydration reaction and oxide film formation.
