Shock sensitivity as measured by the MRL SSGT shows a consistent trend to lower values as %TMD decreases for pressed RDX formulations and some pure explosives such as tetryl. Decrease in particle size, disruption of surface coating, critical diameter and run distance effects were all considered but found not to be the major cause. Comparison of MRL SSGT(More)
The final phase of study into RDX-based formulations suitable for replacement of tetryl in Australian ordnance is described, Three formulations using readily available AC629 emulsifiable polyethylene wax and processible on Australian production equipment are identified. It is recommended that pilot batch production and qualification of RDX/AC629 98.75:1.25(More)
Ionic interactions to stabilize Langmuir films at the air/water interface have been used to develop improved duolayer films. Two-component mixtures of octadecanoic (stearic) acid and poly(diallyldimethylammonium chloride) (polyDADMAC) with different ratios were prepared and applied to the water surface. Surface pressure isotherm cycles demonstrated a(More)
