Abstract:
This paper describes the results of experiments on laser initiation of composites based on PETN and inclusions of submicron coal particles. The thresholds and kinetic characteristics of explosion of mixed compositions based on PETN and inclusions of submicron coal particles (B and DG) are studied under the influence of neodymium laser (1064nm, 12 ns), depending on the mass concentration of inclusions in the range of 0–5%. It is shown that the minimum threshold of explosive decomposition of PETN equal to 1.1 J/cm$^2$ can be achieved if the concentration of both types of inclusions is 0.5%.
