The thermal behaviour of the energetic binder systems GAP, GAP/BDNPA/BDNPF and PEG/BDNPA/BDNPF were investigated by thermogravimetry, derivative thermogravimetry, differential scanning calorimetry and Parr bomb calorimetry. The energetic composites of the above-mentioned binder systems with HMX in various particle sizes have been studied and compared with HTPB composites. It was found that the binder systems all have different thermal decomposition properties and that BDNPA/F is more compatible with GAP polymer than with PEG. The thermal decomposition of the GAP binder system was unchanged when BDNPA/BDNPF was used. However, in the PEG binder system, the decomposition temperature and heat of decomposition increased as the ratio of PEG/ (BDNPA/BDNPF) decreased. In addition, the decomposition temperatures of the energetic composites of this study are lower than that of pure HMX, and the heats of explosion of these energetic composites are proportional to the size of the HMX particles. The glass transition temperatures of the energetic polymer systems in this investigation were not affected by the addition of the nitroplasticiser BDNPA/BDNPF. © 1991.
