Abstract
Several combustible cartridge case (CCC) formulations containing nitrocellulose (NC) as anenergetic ingredient with diphenylamine (DPA) as stabiliser, cellulose fiber as reinforcing materialand polyvinyl acetate (PVAc) as a binder are processed to form combustible discs. A formulationcontaining nitrocellulose (83 parts), cellulose (17 parts) , PVAc (20 parts) and diphenylamine(1 part) by weight was observed with the improvement of mechanical properties without anyadverse effect on combustion characteristics, safety parameters and compatibility with triplebase multi-tubular propellant. Dynamic firing performance was also satisfactory.
