This paper describes thermochemical properties and decomposition characteristics of HMX-based Nitro-HTPB bonded explosive. The thermal stability of three polymer-bonded explosive (PBX) samples containing Nitro-HTPB with various amounts of nitro groups was determined by simultaneous thermogravimetric analysis and differential scanning calorimetry (TG/DSC). The results indicate that nitro content of Nitro-HTPB could affect on thermal stability and its decomposition temperature of PBX samples. Also, Nitro-HTPB bonded explosive decomposes exothermally in a single step. The influence of heating rate on the DSC behavior of the PBX composite material was investigated, while thermal decomposition of this compound followed the first-order law. The critical explosion temperature and kinetic parameters such as activation energy and frequency factor for this explosive compound were obtained from the DSC data by non-isothermal methods proposed by ASTM E698 and Ozawa.
