Characterization of CL-20/PDMS explosive with the disk acceleration experiment (DAX)

Explosive detonation products equation-of-state (EoS) models are typically derived from experimental data on explosive acceleration of metal. The cylinder expansion test has served as the standard method for decades to obtain this information. Recently, the Disk Acceleration eXperiment (DAX) has been developed by researchers at Lawrence Livermore National Laboratory (LLNL) to compliment the cylinder expansion test and provide data on metal acceleration with less explosive. We present experimental work on an explosive formulation of CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane) with PDMS (poly(dimethyl siloxane), Sylgard® 182) using DAX to measure the detonation velocity and metal disk acceleration performance of this explosive.
