ABSTRACT:
Combustible cartridge shells have cylindrical walls formed of combustible material. The walls comprise one or more wraps or windings of textile fibers, which are bound together with bonding agents having propellant charge characteristics. The bonding agents comprise either a mixture of polymers and explosives with decomposition temperatures above 180.degree. C. or a mixture of polymeric nitro-aromatic compounds which have two or more nitro groups per aromatic nucleus and also have a decomposition temperature above 180.degree. C. Mixtures of these two bonding agents may also be used to form the cylindrical wall of the combustible cartridge shell. The cartridge shells have inherently stable walls with a high mechanical resistance and are unaffected by changes in temperature up to 240.degree. C. Advantageously, these shells burn practically free of any residuals.
