The curing kinetics of degradable bio-based epoxy resin containing ester bond was studied by non-isothermal differential scanning calorimetry(DSC).The n-order reaction model,the autocatalytic model and the piecewise model combined by n-order and autocatalytic models were established in sequence.By comparing the model prediction and experimental data,it is concluded that the deviations between the results from n-order reaction model and the experimental curves are large.Although the trends of results from autocatalytic model and experimental curve are basically consistent,there are still deviations.The predictions from piecewise model are in good agreement with the experimental curves,which indicates that the piecewise model could describe accurately the curing reaction process of the epoxy resin system,and provide a theoretical guidance for the optimization of curing process conditions of the resin matrix composites.
