Abstract: A pre-stressed cartridge of the invention generally comprises a cylindrical liner wrapped with a plurality of layers of wound fibers or high tensile wires. These high tension wrapped windings put the walls of the cartridge liner into compression, thus pre-stressing the cylindrical liner. A cartridge constructed in this fashion may develop an ultimate strength in the circumferential direction which approaches ten times the ultimate strength of a typical solid metal cylinder alone. Special reinforcing elements may also be provided, located at the points where the maximum stress is developed upon detonation. Various modifications of this structure include fabricating the liner out of ceramic instead of aluminum, incorporating a steel cup containing the explosive at the base of the internal space of the cartridge, and combining the composite windings with the steel cup to provide a cartridge consisting of a steel cup with the rest of the cartridge being composite fiber windings.
