Abstract

Nitramines explosive, HMX, was used for preparation of gun propellant formulations based on slurry technique. Acrylonitrile butadiene rubber (NBR) was used as a polymer for coating HMX crystals in addition to the traditional Nitrocellulose matrix. Ballistic performance of the compositions was evaluated on the basis of closed vessel test. Heat of combustion was also measured using a calorimetric bomb. Impact and friction sensitivities of the prepared compositions in addition to the ignition temperature were also determined. The obtained results reveal that gun propellant compositions based on approximately 50 percent HMX could provide relatively high performance and relatively suitable sensitivity for its application as gun propellant.
