Abstract

Various epoxy composite materials, such as semiconductor packaging and fiberglass reinforced epoxy composites, are utilized in everyday life and industrial fields. The manufacturing process of these epoxy composite materials is generally carried out under isothermal and non-isothermal conditions in the reaction injection molding (RIM) process. To establish the process conditions, kinetic analysis of curing is necessary, and typical kinetic analysis is performed under isothermal conditions. However, maintaining isothermal conditions at the initial stages of the reaction is difficult, which can lead to errors from the beginning of the reaction. Therefore, by modifying the kinetic equations for application under non-isothermal conditions and conducting nonlinear optimization analysis, it was confirmed that the curing reactions at various heating rates can be effectively represented.
