| Abstract:Thermal property and thermolysis products of a new kind of para-aramid paper based composite, prepared by para-aramid chopped fibre and fibrids, were analyzed by both TG-DSC and TG-IR, and Coats-Redfern Equation was used to investigate its thermal decomposition kinetics behavior. The results showed that this para-aramid paper based composite had three step decomposition process, and its initial decomposition temperature was above 530℃, its 10% weight loss temperature was 540℃. It was found that this kind of para-aramid paper based composite did not melt during pyrolysis with temperature elevating. The main thermolysis products were HCN, NO2, NH3, NO, CO, CO2 and H2O. Its thermal decomposition characteristics was influenced greatly by heating rate, both the initial decomposition temperature and ending decomposition temperature of the sample increased with the increase of heating rate. Coats-Redfern Equation was suitable for calculating its thermal decomposition kinetics parameters, the correlation coefficients of their fitting lines were all above 0.98 and the reaction order was 1. In addition, the activation energy (E) and frequency factor (A) of para-aramid paper based composite under different heating rate were calculated. |
