Abstract
The present invention relates to the field of propellent charges for small and medium calibre arms. The invention relates to a process for the manufacture of fragmentable propellent charges, which consists in a first stage in coating powder particles with a mixture of dinitropolystyrene and of a compound of the polyvinyl nitrate and/or polyvinyl acetate type and, in a second stage, in compressing at between 100.degree. C. and 140.degree. C. the powder particles thus obtained. The invention also relates to the fragmentable charges obtained by the process and to the coated particulate powders obtained at the end of the first stage of the process. The fragmentable charges according to the invention exhibit a temperature behaviour which is superior to that of traditional fragmentable charges and are suitable for cartridgeless ammunition intended for arms with a high rate of fire.
