eng Mutual correlations of mechanical sensitivities to detonation velocity and kinetic parameters for nitramine based PBXs The sensitivities, performances, and decomposition kinetics of nitramine based PBXs are summarized and correlated with each other. The materials with greater critical temperature are usually less sensitive. The polymers could increase both critical temperature and impact sensitivity of nitramines that decompose in solid state. The RDX based materials do not correlate with each other due to the liquid state nature of its decomposition. The higher impact energy corresponds to lower rate constant. The inclusion of polymer binders would decrease the rate constant of CL-20 and HMX that decompose in solid state, while they would increase that of RDX and BCHMX that decompose in liquid or partial liquid state. The heat of decomposition represents the energy content of the explosive samples, and a higher energetic content is responsible for lower impact sensitivity.
