Abstract : The present invention relates to a method of making combustible cartridge cases, and more particularly with the method of making cellulosic cartridge cases which possess the required physical strength and which will burn completely when fired in conventional weapons. The elimination of the conventional metal case results in a considerable saving in weight; the problem of disposal is eliminated and there is a saving of metals which might become critically short in supply during times of emergency. In general, the method of this invention contemplates the treatment of fibrous organic materials, preferably fabrics such as cotton gauze, with a slurry of solid oxidizing agent in a solvent solution of a resin. Impregnation or coating of the fabric material, which is generally in strip form, may be accomplished by any suitable apparatus.
