Abstract

The cure kinetic equation fur 52-glass/polyester prepreg composites was established through DSC (differential scanning calorimetry). Using the established kinetic equation, the temperature distribution of the thick composite was calculated considering the change of heat transfer resistance due to resin impregnation of bleeder plies used. In order to reduce the overheat during cure of thick glass fiber composites, the cure cycle was modified by introducing the cooling and reheating steps. Then the thick glass composites were cured both by the conventional cycle without any cooling or reheating step and the modified cure cycle. The mechanical properties of the thick composites cured by the both cycles were tested by the short beam shear test and the Barcol hardness test, and then their results were compared.

DSC(differential scanning calorimetry)를 이용하여 S2-유리섬유/폴리에스터 프리프레그 복합재료의 경화반응식을 구성하였다. 구성된 경화식과 블리더의 수지 함침에 의한 열전달 조건의 변화를 고려하여, 두꺼운 복합재료의 두께 방향 위치에 따른 온도분포를 계산하였다. 유래섬유 복합재료의 경화중 온도과승을 줄이기 위한 방법으로 냉각 및 재가열 구간을 도입하여 경화 사이클을 개선하였다. 냉각-재가열 구간이 없는 기존의 경화 사이클과 개선된 경화 사이클로 두꺼운 복합재료를 각각 제조하여 short beam shear 시험 및 Barcol 경도시험을 실시하고, 그 결과를 비교하였다.
