Detonation wave structure of CL-20 composite explosive

The detonation reaction of CL-20 composite explosive was numerically simulated to analyze its detonation reaction characteristics, and then an experimental setup was designed for measuring the particle velocity at the explosive-window interface. The laser interference method was used to measure the particle velocity at the interface between the LiF window and the C-1 explosive, and ninety-four percent of the C-1 explosive is CL-20 and six percent is binder by weight. And the measured particle velocity-time curves were processed by the method of derivation and piecewise fitting to determine the corresponding CJ point. According to the corresponding CJ velocity, the reaction time and CJ pressure were determined. The detonation reaction time of the C-1 explosive with the density of 1.943 g/cm³ is 38 ns and the CJ pressure is 34.2 GPa.
