Abstract

Combustible cartridge case (CCC) offers specific advantages over the conventional metallic (brass) case. The CCCs are made of cellulose fibres with suitable explosives to ensure debris-free combustion inside the gun barrel. The presence of explosives in CCC, however, causes increased vulnerability to cook-off. An experimental study of cook-off of CCC was carried out by hot plate technique. Cook-off data for CCC of different compositions and with various cook-off delay coatings was measured. It was found that out of four types of coatings, two gave better results.
