Combustible Cartridge Cases: An Account of the Current Technology and Proposals for Future Development

摘要

Combustible cartridge cases are at present produced either by the beater additive or by the post impregnation process. The literature covering these techniques, which basically follow the concept of fibre moulding and/or papermaking, is reviewed. The various processing steps used in the manufacture of these cases, namely, beating, fibre felting and moulding, and resin application are discussed. Particular attention is given to characterising the potential problems associated with the production and use of combustible cases. These include inherent lack of mechanical strength, low porosity, vulnerability to penetration of water and water vapor, and problems related to materials used for fabrication, and complete combustion. In this contex, the general areas requiring further research are indicated.
