Abstract


Four PTFE/Al/Bi2O3 ternary reactive materials with different Al contents were prepared by molded sintering method to obtain the influence of Al content on the mechanical properties and impact reaction characteristics of PTFE/Al/Bi2O3 ternary reactive materials, and their mechanical and reaction properties were tested by drop-weight test and the shock induced reaction phenomena were observed by high-speed camera. The results show that the characteristic drop height first decreases and then increases as the Al content increases from 24% to 48%, and the reaction delay time remains unchanged, and the reaction duration first increases and then decreases. When the Al excess is doubled, its reaction is the most intense, the duration is the longest, and the reactivity reaches the strongest. The results of the study can provide some reference for the engineering application of PTFE/Al/Bi2O3
