| Abstract: | The curing kinetics of epoxy resin was studied by non-isothermal DSC. The reaction activation energy, reaction order and pre-exponential factor were calculated by Kissinger equation, moreover, the activation energy of curing reaction was verified by Ozawa equation. The results showed that curing reaction of EP/DDS was consistent with n-order kinetic model. Furthermore, the curing condition of epoxy resin was optimized according to the characteristic temperature at different heating rates. |
