In order to solve the problem of stratified settlement of traditional loose charges, solid-state fuel air explosives have been rapidly developed in recent years. In this paper, two solid-state fuel air explosives with PTFE and HTPB as binder systems were proposed, and two kinds of solid-state fuel air explosives were used at different strain rates by using a separate Hopkinson pressure bar (SHPB) experimental device. The dynamic mechanical properties were studied. Simultaneous high-speed photography was used to observe the damage and pulverization behavior of the two fuel air explosives at high strain rate. The failure response modes of the two fuel air explosives were analyzed. The results showed that the PTFE-based fuel air explosives the strain wave responds faster and is more sensitive to variability. [ABSTRACT FROM AUTHOR] |
