Abstract: The mesoscopic structures of β-HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine)-based PBXs (polymer bonded explosives) at room temperature were investigated using dissipative particle dynamics method. The parameters and repulsive parameters of dif-ferent polymers and β-HMX, the mesoscopic structures of β-HMX-based polymer-bonded explosives at different temperatures have been studied. The results showed that the compat-ibility between β-HMX and vinylidenedifluoride (VDF), β-HMX and chlorotrifluoroethylene(CTFE), VDF and CTFE increased with increasing temperature. The temperature and mo-lar ratio of the polymers played an important role in wrapped process. And there exists the optimum temperature and molar ratio.
