Abstract
불포화 폴리에스테르수지-BPO계의 경화반응속도를 348-378 oK의 온도범위에서 연구하였는 바, 경화속도식은 경화유도시간과 최대경화도를 도입하여 개선하였으며, 속도식의 파라미터들은 시차 주사열량계（Differential Scanning Calorimeter）를 이용한 실험을 통하여 결정하였다.
본 연구에서는 제안된 속도식을 검토하기 위하여 압축성형공정에 관한 수치모사와 실험도 병행하였으며, 그 결과 본 연구에서 제안된 속도식을 이용하면 성형공정의 수치모사를 보다 성공적으로 수행할 수 있음을 확인하였다.

The curing kinetics of unsaturated polyester resin with benzoyl peroxide was studied within the temperature range of 348-378 oK. A modified kinetic expression was devised by introducing cure induction time and maximum degree of cure, and the kinetic parameters were determined using differential scanning calorimetry.
We also carried out both numerical and experimental studies on compression molding processes of the resin system in order to test the proposed kinetic equation. From the results, it was found that the present kinetic expression enabled us to predict the molding process successfully.
