    Abstract
  • The pressure evolution of shock initiation for IHE's JB9014 at ambient and -54 ℃ was investigated experimentally using embedded manganin gauges. The pressure evolution observed in JB9014 at -54 ℃ shows homogeneous initiation mechanism, by comparison, these observed in JB9014 at ambient temperature show a combination of homogeneous and heterogeneous initiation mechanism. The results show that JB9014 at -54 ℃ becomes significantly less sensitive to shock than at ambient temperature and that JB9014 is less shock sensitive than PBX-9502 with same TATB/binder ratio at both ambient temperature and -54 ℃.
