Environmentally Benign Stab Detonators
Abstract
This work details the stab ignition, small-scale sensitivity, and energy release characteristics of bimetallic Al/Ni(V) and Al/Monel energetic nanolaminate free-standing films. The influence of the engineered nanostructural features of the multilayersiscorrelated with both stab initiation and small-scale energetic materials testing results. Structural parameters of the thin films found to be important include the bi-layer period, total thickness of the film, and presence of coating Al layers. Live lead-free M55 stab detonators were prepared using energetic nanolaminate as the stab mix, cyanuric triazide as the transfer charge, and an Army formulation for the output charge. These lead-free detonators were demonstrated to have the acceptable stab sensitivity (21-35 mJ) as is required in current M55 detonators. There was evidence that the replacement of the current NOL-130 stab mix by compact powders of energetic multilayers does not affect the performance of the stab detonator.
