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, NH2 and/or
similar functional groups, and is capable of forming chemical bonds and/or engaging
in intermolecular interaction with the cellulose or nitrocellulose molecules.
