Shock sensitivity of LX-04 at 150C

PDF Version Also Available for Download.

Description

Hazard scenarios can involve multiple stimuli, such as heating followed by fragment impact (shock). The shock response of LX-04 (85 weight % HMX and 15 weight % Viton binder) preheated to temperatures near 150 C is studied in a 10.2 cm bore diameter gas gun using embedded manganin pressure gauges. The pressure histories at various depths in the LX-04 targets and the run distances to detonation at several input shock pressures are measured and compared to those previously obtained in ambient temperature and 170 C LX-04. Since the beta to delta phase transition in HMX occurs at 165 C, these ... continued below

Description

Hazard scenarios can involve multiple stimuli, such as heating followed by fragment impact (shock). The shock response of LX-04 (85 weight % HMX and 15 weight % Viton binder) preheated to temperatures near 150 C is studied in a 10.2 cm bore diameter gas gun using embedded manganin pressure gauges. The pressure histories at various depths in the LX-04 targets and the run distances to detonation at several input shock pressures are measured and compared to those previously obtained in ambient temperature and 170 C LX-04. Since the beta to delta phase transition in HMX occurs at 165 C, these experiments are designed to determine whether the observed increase in shock sensitivity is due in part to the 6% volume expansion caused by this phase transition. The experimental shows that LX-04 exhibits the same sensitivity at 150 C and 170 C. The Ignition and Growth reactive flow model developed for 170 C LX-04 works equally well for LX-04 at 150 C.
