Application of cis-1,3,4,6-Tetranitrooctahydroimidazo-[4,5d] Imidazole (BCHMX) in EPX-1 Explosive

Abstract

3,4,5 d]imidazole (BCHMX) has been studied as explosive filler to replace pentaerythritol tetra-nitrate (PETN) inEPX1 explosive. BCHMX with different particle sizes was bonded by thermoplastic binder plasticised by dibutyl phthalate to obtain BCHMX-EPX. Heat of combustion was measured. Impact energy and friction force of initiation were determined. Velocity of detonation was measured, while the detonation characteristics were calculated by thermodynamic code named EXPLO 5. For comparison, the detonation characteristics of some commercial plastic explosives such asEPX-1, SEMTEX 10 and FORMEX P1were also studied. It was concluded that BCHMX-EPX has the highest detonation characteristics of all the studied plastic explosives and its sensitivity is in the same level of the studied traditional plastic explosives. BCHMX-EPX has the highest decomposition temperature of all the studied samples. The mutual relationship obtained from the experimental and calculated results indicates the compatibility of the calculated results with the experimental measurements.

New Mechanistic Insights into the Primary Thermolysis Reactions of 1,3,4,6-Tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) from Predictive Local Coupled Cluster Calculations

“…In order to cope with sensitivity issues, BCHMX was tested as a component of energetic compositions. − The coating polymer matrices were found both to improve thermal stability , and reduce the sensitivity of the compositions. − Apart from this, the PBX compositions of BCHMX with low sensitivity EMs such as NTO and FOX-7 exhibited better performance than their counterparts with RDX and HMX. Thermal stability of these compositions was close to that of a neat BCHMX. , Moreover, Elbeih et al .…”

Ballistic Protection of Military Shelters from Mortar Fragmentation and Blast Effects using a Multi layer Structure

“…The continuous development in the various ammunitions in the main battle fields led to the developments of advanced energetic explosive materials [1][2][3][4] and its accompanied destructive effect as well as the ballistic threat containing the directed energy devices such as shaped charges, blasting charges and dual purpose fragmenting charges. As a result, mortar bombs have become more efficient in the current battle fields, military missions and terror attacks.…”

The effect of glycidyl azide polymer on the stability and explosive properties of different interesting nitramines

“…3,4,10 Elbeih et al [10][11][12][13][14][15][16] have studied the explosive properties of different plastic bonded explosives (PBXs) based on several nitramines including BCHMX. In addition, a thermoanalytical study of these PBXs was conducted by Yan et al [17][18][19] The penetration performance of the advanced nitramines has been studied, [20][21][22] while different relationships have been presented and discussed by Zeman et al [23][24][25][26] based on the reactivity and sensitivity of the studied PBXs.…”
