ABSTRACT:
A method for producing a combustible cartridge case for cartridge ammunition, wherein an aqueous pulp containing nitrocellulose and cellulose fibers is produced, a raw felt is produced from the pulp through draining the fiber material on a sieve, and the raw felt is then compressed and shaped. To produce combustible cartridge cases possessing a greater mechanical stability than known cartridge cases of comparable dimensions, additives are mixed into the aqueous pulp prior to the production of the raw felt, to increase the stability of the fiber composite after the compressing process, so the breaking strength and the breaking elongation, and the resistance to tear propagation are increased. The additive is preferably a polymer material having a hydrophilic character and a high content of OH, NH2and/or similar functional groups, and is capable of forming chemical bonds and/or engaging in intermolecular interaction with the cellulose or nitrocellulose molecules.
