Effects of Surface Interactions and Mechanical Properties of PBXs (Plastic Bonded Explosives) on Explosive Sensitivity

摘要

Much of the first year's effort was spent on materials acquisition, preparation, and characterization. For this study, four binders were selected as the baseline materials. The surface properties of these binders were determined and the results were used to predict the bonding behavior between each binder and RDX. A fracture free energy model was used to predict the bond stability of each RDX-binder system. Model formulations are being made using the baseline binders. Experimental samples from one mix were sent to evaluators at NWC. The samples were used to determine ignition characteristics, mechanical properties, thermal properties and sensitivity characteristics.
