Improving the energetic properties of 1,1-diamino-2,2-dinitroethene in PBX mixture

Abstract The new eyesight in the energetic materials focuses on reserving high efficiency together with optimization of safe handling. In this study, a novel nitramine, cis1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX), is combined with 1,1diamino-2,2-dinitroethene (FOX7), and bound by a styrene-butadiene rubber fabricating an insensitive plastic bonded explosive (PBX) mixture. The obtained PBX was fully characterized in comparison with the familiar explosives; SEMTEX, EPX1 and other PBXs, filled by RDX (1,3,5trinitro-1,3,5-triazinane), HMX (1,3,5,7tetranitro-1,3,5,7-tetrazine). The related individual fillers were also included. Sensitivities to various stimuli and the velocities of detonation were measured for the composites in comparison with the selected explosives. EXPLO 05 has been applied to obtain the detonation properties of the tested explosives. Different relationships (comparing performance with sensitivities) are stated and discussed. The results showed that BC/FOX7 - SBR has very low sensitivity compared with the studied compositions while its performance has larger values.
