Abstract (en)
[origin: EP0481838A1] A relatively insensitive component of explosive ammunition consisting of a casing containing a multicomposition explosive charge in which the innermost layer is a composite explosive consisting of a filled polyurethane or polyester polymeric matrix in which the filler contains more than 40 % by weight of organic nitro explosive and in which the peripheral layer is a pyrotechnic composition of the class of composite solid propellants, consisting of a filled polyurethane or polyester polymeric matrix in which the filler contains at least one inorganic oxidiser and less than 10 % by weight of organic nitro explosives. The blast and/or bubble effect produced is close to that produced by the much more sensitive charge of a single-composition composite explosive of equivalent mass. <??>The invention also relates to a process for obtaining a blast and/or bubble effect by release of gas in the casing of an abovementioned component of ammunition according to the invention followed by a rupture of the casing. The gas release is obtained by detonation of the innermost layer followed by a detonation-free reaction of the peripheral layer.
