Abstract

The research on curing processes in Resin Transfer Molding is helpful to control the chemical reaction, material structures and properties.In this paper, the chemical kinetic equations of curing processes, crosslinked structure parameters equations and the temperature basic equations are founded in the curing processes. The finite element method is adopted to simulate the curing processes to analyze the influence and changes of temperature, curing ratio and crosslinking degree.
