Abstract: High performance aluminized explosive compositions for high performance, high blast, low sensitivity explosive applications are disclosed. The compositions include Cl-20, HMX, RDX, or another material as the explosive ingredient, a binder system of cellulose acetate butyrate and bis-dinitropropyl acetyl and bis-dinitropropyl formal, and aluminum. The explosive is preferably pressable and or/mixable to permit formation into grains suitable for ordnance and similar applications including grenades, warheads, landmines, demolition, etc. The aluminum fully participates in the detonation of said explosive, manifesting its energy into fully useable metal pushing energy suitable for shaped charges, explosively formed penetrators, fragmentation warheads, enhanced blast warheads, multipurpose warheads, and the like. The aluminum is substantially reacted at two volume expansions of the expanding gas, and fully reacted prior to seven volume expansions of the expanding gas.

Abstract: A combustible cartridge case is provided that includes at least one energetic thermoplastic homopolymer or copolymer derived from, at least in part, poly(bis-azidomethyloxetane) prepolymer blocks terminated with isocyanate-reactive groups, such as hydroxyl groups. Chain linking of the prepolymer blocks is performed with diisocyanates for end-capping the prepolymer blocks, and a difunctional linking compound for linking the end-capped prepolymer blocks. The energetic thermoplastic is preferably capable of being pressed, extruded, rotational molded, injection loaded, or otherwise shaped into a desired configuration. Also provided is a chain-extended poly(bis-azidomethyloxetane) homopolymer derived from bis-azidomethyloxetane prepolymer blocks, which are terminated with isocyanate-reactive groups and chain extended with at least one diisocyanate end-capping compound and at least one difunctional linking compound.
