ABSTRACT:
The present invention relates to an effective and explosive munition component of low vulnerability, consisting of a casing 1 containing an explosive charge consisting of an internal layer 2 made of plastic bonded explosive in which the filler contains at least one organic nitrated 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 oxidizing agent or an organic nitrated explosive.
The interface between the two layers 2 and 3 is of star-shaped cross-section.
The invention also relates to the process for obtaining a fragmentation effect by detonation of the layer 2, reaction of the layer 3 followed by bursting of the casing due to the pressure of the gases formed.
