The explosive energy release characteristics of thermobaric explosives with different binder systems during detonation are studies.Two types of HMX-based thermobaric explosives with similar formulations are selected for testing of detonation heat，detonation velocity，detonation driving performance，and internal explosion performance.In addition，the influence of differences in the binders on the reaction rate of aluminum powder and the release process of explosive energy in thermobaric explosives is analyzed.The results indicate that the aluminum powders in thermobaric explosives with different binder systems show significant differences in the reaction and energy release processes.Among them，the reaction rate of aluminum powder in thermosetting casting thermobaric explosives is faster than that of aluminum powder in thermoplastic casting thermobaric explosives.Moreover，the aluminum powder involved in aerobic combustion of thermoplastic casting thermobaric explosives is more than that involved in aerobic combustion of thermosetting casting thermobaric explosives，resulting in the expansion mechanical energy converted by its thermal effect compensating for the insufficient mechanical energy converted by shock waves.In summary，this research provides experimental evidence and support for the selection of charges and the estimation of destructive performance for the relevant warheads.
