Abstract

Abstract: The epoxy resin E54 was added with different proportions of the trifunctional meta-aminophenol epoxy resin S500M and was used to prepare the epoxy resins which has different cross-linked structures with the DDS curing agent. The non-isothermal DSC method was used to analyze the curing process of epoxy resin, and the curing degree versus temperature curve was drawn according to the curing reaction heat. The activation energy and kinetic parameters of the epoxy resin systems were obtained by using Kissinger and Crane equations. With the increase of crosslinking density, the results showed that the starting temperature, peak temperature and termination temperature of the curing reaction moved forward, the curing time was shortened, and the activation energy of curing reaction was decreased, but the frequency factor and reaction order were basically unchanged.

Key words: cross-linking structures, epoxy resin, curing kinetics, composites
