The fluoropolymer-based reactive material is a kind of sub-stable energetic composites which contain metal powders, fluoropolymer and fillings. It is also a new kind of energetic material widely reported in recent years. In this paper, the PTFE/Al reactive material was prepared by using the cold press and hot sinter method. The physicochemical performance and mechanical property of PTFE/Al were studied, and the pressing and sintering technical parameters were optimized.
