Abstract

Nowadays more and more large composites are used to replace the traditional metallic structural materials in the industries. However, for manufacturing the thick thermoset composites, the size not only influences the mechanical properties in the completed products, but also the core temperature overshoot generated during the curing reaction. This study is focusing on the heat transfer phenomenon in the thick thermoset composites during cure. A heat transfer coupled cure kinetic system was established to predict the temperature distribution in the composite. In this thesis, the research mainly consists of analytical modeling, numerical modeling and experimental validation. The results show that the analytical and numerical analysis agrees with the experiments well.
