Kevlar/Epoxy 프리프레그의 보관 및 노출시간의 영향에 관한 연구
諸葛英淳 慶一大學校 2002 論文集 Vol.18 No.-
The effect of storage and exposing time of a Kevlar/Epoxy prepreg for NOSE CONE fabrication was studied by various instrumental methods such as NMR, IR, GPC, etc. It was found that the chemical structure and compositions of the Kevlar/Epoxy prepreg after 1 year at the temperature of -20℃ were similar with those of a new Kevlar/Epoxy prepreg. The exposing time at the room of 20℃ was also found to be not severe even after 10 days of exposing time.
