Description
| - Four plastic explosives based on energetic nitramines and a non-energetic binder were prepared and studied. The nitramines were RDX (1,3,5-trinitro-1,3,5-triazine), HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazine), BCHMX (cis-1,3,4,6-tetranitro-octahydroimidazo-[4,5-d]imidazole) and HNIW (epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane, epsilon-CL-20). The binder was in all cases polyisobutylene (PIB) as in the standard composition C-4. These powerful plastic explosives were compared to standard PETN-based commercially available explosives Semtex 1A and Sprängdeg m/46. The detonation velocities were experimentally measured and compared to the ones calculated by the Kamlet-Jacobs method, CHEETAH and EXPLO5 Codes. The experimental detonation velocities as well as the calculated detonation parameters decrease in the following order: HNIW-PIB}HMX-PIB?BCHMX-PIB}RDX-PIB}Sprändeg m/46?Semtex 1A. Urizar coefficients for the various binders were calculated from experimental data.
