Abstract
Thermodynamic calculations of the adiabatic temperatures and probable compositions of the combustion products in the W–PTFE and W–Al–PTFE systems were performed. Powdered reactive compacts were produced. The shock-wave loading of reactive materials in the W–Al–PTFE system was studied. It was shown that the systems based on tungsten and polytetrafluoroethylene are generally difficult to initiate; nonetheless, the addition of aluminum increases their shock-wave sensitivity and makes it possible to reach the calculated combustion temperatures more than 3000 K, which enables one to consider such mixtures promising for the development of high-density reactive materials.
