ABSTRACT:
The invention is directed to a formable homogeneous propellant composition and to a process employing same for production of a self-supporting formed propellant charge. The propellant composition comprises a mixture of propellant grains and solvent-filled microcapsules in proportions suitable for consolidation under pressure to form the self-supporting formed propellant charge. The solvent-filled microcapsules comprise solvent suitable for partially solvating the propellant grains. The mixture of propellant grains and solvent-filled microcapsules are placed in a forming mold under sufficient pressure to rupture at least a substantial portion of the microcapsules. Pressure is maintained for a time sufficient to form the self-supporting formed propellant charge, after which the propellant charge can be removed from the forming mold and cured by exposure to drying heat.
