The temperature and viscosity of heated epoxy resin largely change due to a chemical reaction. Defects in cast epoxy resin, such as cracks, voids and shrinkage, are closely related to the temperature and viscosity history in the curing process. However, reaction kinetics has not been applied for analyzing the polymer reaction rate in nonisothermal curing process. In this study, the mathematical model for the amount of heat generation due to reaction in nonisothermal casting is proposed. Furthermore, the differential equation, describing the relationships among viscosity, temperature, and time, is derived based on the results of viscosity measurement. Our analytical technology, which takes the amount of heat generation due to reaction into consideration, makes it possible to solve not only the temperature history but also the viscosity distribution in the nonisothermal casting process for arbitrary shape components. Using this technology, large insulating components superior in quality have been developed.
