QUALITY EVALUATION OF FOAMED PROPELLANTS

摘要

Foamed propeliants are based on crystalline explosives bonded in energetic reaction polymers. Due to their porous structures they are distinguished by high burning rates. Energy content and material characteristics can be varied by using different energetic fillers, energetic polymers and porous structures. Foamed propeliants can be produced by the reaction injection moulding process (RIM). The properties of the propeliants have to show a high reproducibility in order to provide, a proper function in the weapon. Therefore a lot of quality studies of propellant charges have been performed. The evaluation of the quality of foamed propeliants manufactured by the reaction injection moulding process by different methods will be presented in this contribution.
