As a kind of high explosives, aluminized explosive cannot release the energy maximumly, which is a key problem. Using DTA-TG\nequipment, the ignition performance of three kinds of aluminized explosives (RDX, HMX, and CL-20) with different mass\npercentages of aluminum powder (0%, 10 wt.%, 20 wt.%, and 30 wt.%) was investigated. The results showed that the energy release\nof the HMX/Al composite explosive with 10 wt.%, 20 wt.%, and 30 wt.% aluminum powder was only equivalent to 80%, 65%, and\n36% of pure HMX, respectively. It was similar to RDX/Al and CL-20/Al composite explosives, except the CL-20/Al mixture with\n10% aluminum powder. Rather than participating in the ignition and combustion, the aluminum powder does effect the complete\nreaction of RDX, HMX, and CL-20 in the initial stage of ignition or in the lower temperature area of the boundary.
