Abstract
A method is described for improving the mechanical stressability of ammunition bodies, particularly shaped charges, which are highly accelerated and/or subjected to shock waves by coating the contacting portion of the cavity. In a first step of the method, the charge liner is coated on its outer surface and the case is coated on its inner surface with a styrene-containing copolymer; in a further step of the method, the explosive charge is cast or compressed in a known manner. The method finds use particularly for the production of tandem shaped charge projectiles.
