Curing Kinetics Study of Epoxy Resin at Nonisothermal Conditions

To determine the kinetics characteristics of thermoset resins, it is required to optimize curing conditions due to their dependency on time, temperature and curing conditions. In this work, curing kinetics of epoxy resin 5052, with amine-based hardener was investigated using DSC at nonisothermal conditions with various heating rates. Kinetic parameters were firstly deduced experimentally using isoconversional method, which was introduced by Malek. Then, by choosing Sestak-Berggren model, the experimental data obtained from DSC showed good agreement with this model. Considering this model, it is able to interpret the curing behavior of resin at various thermal and time dependent conditions.
