| Abstract: | An analysis of the cure kinetics of epoxy resin/amino polycarbonate system was performed. The dynamic DSC thermograms were analyzed with the help of Ozawa method and ASTM kinetic software to determine the kinetic parameters of the curing reaction, including the activation energy, pre exponential factor, and 60 min 1/2 life temperature. The effects of different amino polycarbonate concentration on curing behaviour, and kinetic parameters were discussed. |
