Low-sensitivity component of explosive ammunition comprising a dual composition explosive charge and process for obtaining a fragmentation effect

摘要

High-performance and low-sensitivity component of explosive ammunition consisting of an enclosure 1 containing an explosive charge consisting of an inner layer 2 made of compound explosive in which the filler contains more than 20 % by weight of organic nitro explosive, coated with a peripheral adjacent coaxial layer 3 made of less sensitive pyrotechnic composition consisting of a filled polymeric matrix in which the filler contains at least one inorganic oxidiser or an organic nitro explosive. The interface between the two layers 2 and 3 has a star-shaped cross-section. The invention also covers the process for obtaining a fermentation effect by detonation of the layer 2, reaction of the layer 3 and then rupture of the enclosure due to the pressure of the gases formed.
