The curing reaction of an aliphatic epoxy resin and EPDM rubber is modeled from differential scanning calorimetry, generalizing a methodology proposed by Hernandez-Ortiz and Osswald. The kinetics is represented by Kamal-Sourour model with and without diffusion reaction control and was extracted using a non-linear regression method coupled with the heat and mass balance equations. The kinetic fitting methodology uses dynamic and isothermal differential scanning calorimetries allowing the differentiation of high and small peaks during the curing and diffusion reaction control regimens.
