| Abstract: | The energy release characteristics of six different kinds of energetic fragments were measured based on Split Hopkinson Pressure Bar(SHPB)and Vented Chamber Calorimetry test method. The fireball change process of energetic fragments were acquired by a high-speed camera. The results show that energetic materials have greater damage effectiveness than inert materials. Al/W/PTFE energetic fragments release the maximum amounts of thermochemical energy under impact loading, and the reaction duration of Ti/W/PTFE energetic fragments is the longest. |
