Abstract

The cure kinetics of middle temperature curing 3234 epoxy resin system was studied under isothermal and dynamic curing conditions by Differential Scanning Calorimetry (DSC) technique. The cure kinetic equations were established. By simulating practical temperature procedure of curing, the cure kinetic equations were verified by means of determining the residual heat of reaction of samples with different cure degrees. The results showed that the cure kinetics can be described by the autocatalytic kinetic model . The cure kinetic equation obtained from dynamic test agreed well with the experimental results.
