In this work, thermal degradation behavior of a solid composite propellant containing Epoxy/Ammonium perchlorateStrontium nitrateAnthracene composite was studied by simultaneous thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. Variation curves of the thermal degradation activation energy of EpoxyAmmonium perchlorateStrontium nitrate, EpoxyAmmonium perchlorateAnthracene and EpoxyAmmonium perchlorateStrontium nitrateAnthracene calculated were evaluated by differential and integral isoconversional methods and AKTS software package. Self-accelerating decomposition temperature and explosion critical temperature of the composites has been determined to evaluate their thermal stability. Thermal degradation activation energy and pre-exponential factor of the composites were determined by Kissinger method. Finally, life-time prediction of the composites was done by AKTS software.
