Foster, P A; Demerson, E L

Five explosives (LX-10, PBX 9501, PBX 9502, HMX/Kraton, and RX-03-DI), were aged in helium and air atmospheres at temperatures of ambient, 40, 50 and 70 C for 18 months. Thermal analysis (CRT, Henkin, DSC) showed little change in the explosives. Friction tests indicate the PBX 9501 to be less sensitive after 70 C aging which is probably due to binder degradation. Atmospheric analysis of the contaiers with PBX 9501 shows the explosive undergoes degradation (probably binder) at the 70 C temperature. It appears that LX-10 may become more friction sensitive after aging. No conclusions could be reached regarding the effect of thermal aging on the friction sensitivities of the other explosives.
