摘要：

The thermal behaviour of a series of epoxy-cured resins was studied by TGA, DSC and FTIR. Three systems with different epoxy/amine (DGEBA/ETDA) ratios and three with a constant epoxy/amine ratio and 30% of various metallic fillers (Al, Cu, Zn) were studied. The TGA results were analysed by applying the Freeman-Carroll and Coats-Redfern methods. It is found that there is a decrease in the activation energy of thermal decomposition in the non-filled systems when the epoxy/amine ratio is increased and also in the presence of metallic fillers.
