In order to evaluate the fire hazard of epoxy resin,a methodology for analyzing the pyrolysis characteristic of epoxy resin cured with cardanol-based phenalkamine(EP-PAA)was detailed using ThermaKin modeling frame-work.First,through inverse modeling of thermogravimetric analysis(TGA)experimental results,the kinetics of thermal decomposition of EP-PAA was parameterized.Second,the heat capacities of condensed-phase components and the heat of reactions were obtained through inverse modeling of the differential scanning calorimetry(DSC)ex-perimental results to develop the comprehensive thermal decomposition mechanism.The findings of this work dem-onstrate that the mass loss curve of EP-PAA mainly appeares in the temperature range between 550-800 K,and the mass loss rate(MLR)curve has two peaks;the developed reaction model including two first-order endothermic reactions accurately captures the TGA and DSC experimental results.The reaction model is able to predict the ex-perimental final mass residue and MLR peaks within 5％and 8％,respectively,which further validates the accuracy and reliability of the developed reaction model.
