High char yield BPR modified with ZrSi2 and B4C: Pyrolysis kinetic behavior and structure evolution
BPR has been widely used as ablative material for thermal protection on aircraft surface. In this study, model-free method was employed to study the kinetic models of BPR and ZrSi 2 /B 4 C-Ph composite. In addition, the thermal stability, chemical reaction and structure evolution during pyrolysis of...
