Pulsed electrical breakdown of energetic composite condensed systems

An experimental study was made of 0.2 fusec pulsed electrical breakdown of energetic composite systems containing a polymer binder capable of self-sustained combustion. It is shown that electrical breakdown of samples 2–4 mm thick does not lead to ignition of the entire sample but can cause severe damage to it. The effect of dispersed fillers on the electric strength and fracture of energetic condensed systems in comparison with nonflammable polymer compositions is discussed.
