Flexible plastic explosives with rubber NBR during artificial ageing

This paper investigates chemical and thermal stability of flexible PBX's during their artificial ageing in term of their similar plastic binder. It was documented, they contain the rubber NBR and the similar base (RDX, PETN or RDX with PETN), but they don't have equivalent behaviour during the artificial ageing. It was discovered one from them is chemically unstable, because probably the rubber NBR is incompatible with RDX.

In this paper is compared computer modelling of the fragmentation warhead effects in dependence of variety high explosives with practical test results. For the fragmentation modelling was used analytical code SPLI-X version 3.02. SPLIT-X is an expert system for the design of fragmentation warheads. The influence of next high explosives on fragmentatio effect was compared: cast trinitrotoluene (TNT), mixture explosives TNT/RDX/wax and insensitive HE type of the plastic bonded explosives (PBX) NTO/RDX/IB (IHE).
