Resonant acoustic mixing (RAM) of an explosive composition

A process for filling a munition with a homogenous crosslinked polymer bonded explosive composition, the process comprising:

• forming an admixture of a pre-cure castable explosive composition, said composition comprising an explosive material, a polymerisable binder, and a microencapsulated cross linking reagent, said microencapsulated cross linking reagent comprising a cross linking reagent encapsulated in a microcapsule, wherein the microcapsule, comprises at least one shell wall polymer, wherein the microcapsule's shell wall polymer comprises at least one resonant acoustic stimulus labile linkage;
• filling the munition with the admixture;
• and
• applying a resonant acoustic stimulus to the munition, thereby causing the microcapsule to rupture and release said cross linking reagent.

A continuous filling process for filling a plurality of munitions with a homogenous crosslinked polymer bonded explosive composition, the process comprising:

• forming a pre-cure castable explosive composition by providing a continuous feed of an explosive material, a polymerisable binder, and a cross linking reagent into a continuous resonant acoustic mixer;
• applying a resonant acoustic stimulus to the continuous resonant acoustic mixer to form the homogenous crosslinked polymer bonded explosive composition;
• and
• filling the plurality of munitions with the homogenous crosslinked polymer bonded explosive composition.
