Influences of CNTs on Thermal Decomposition and Impact Sensitivity of HMX

摘要

Mixed explosive (HMX/CNTs) was prepared and its surface topography was characterized. The thermal decomposition property was analysed by the DSC method and the thermal explosion method. Compared with pure HMX, the thermal decomposition temperature of HMX/CNTs decreased a little. The test results of impact sensitivity and friction sensitivity test indicate CNTs can effectively desensitize HMX, and that the impact sensitivity descreases greatly with the increase of the CNTs content.
