Cook Off Study of Combustible Cartridge Cases

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.
