摘要
Metal/fluoropolymer composites represent a new category of efficient damage element that releases energy through exothermic chemical reactions initiated under shock loading conditions. This paper describes an experiment designed to study the reaction characteristics of PTFE(polytetrafluoroethylene)/Ti/W energetic materials with different W mass fractions under explosive loading. An inert PTFE/W mixture without reactive Ti particles is also prepared to serve as a reference. Shock-induced chemical reactions are recorded by high-speed video through a narrow observation window. Related shock parameters are calculated based on experimental data, and differences in energy release are discussed. The results show that the reaction propagation of PTFE/Ti/W energetic materials under explosive loading is not self-sustained. Propagation distance, W mass fractions and porosity have significant influences on the energy release.
