Abstract: Hot-spot mechanisms at the grain-scale play an important role in explosive behavior, especially in shock initiation sensitivity, and detonation properties coupled to shock-initiability.To better understand how dilution of energetic concentration affects its performance, we investigated the detonation properties of dilute plastic bonded explosives (PBX) comprised of 20-60 wt.% PETN in a silicone-based polymeric binder.With the intention of probing low performance in dilute PBX formulations, we attempted to get a formulation with a PCJ as low as 3 GPa and a Dvel of 3 mm/μs as well as cast densities within 3% of the theoretical maximum density to ensure consistent void-volume control.
