Evaluation of Electroformed Copper for Shaped Charge Applications.

摘要

In this paper, we present our observations of the behavior of conical shaped charge liners electroformed in a proprietary acid copper sulfate solution and compare these to the dynamic failure observed in rapidly expanding ring experiments with the same material. Although the electroforms performed poorly in both tests, exhibiting low ductility at the high strain rates encountered, results from the two tests agreed quite favorably. This suggests that the electromagnetic ring test, which is considerably less expensive to perform than explosive tests on full size liners, can be used as a screening test for evaluating materials for shaped charge liner applications. Reasons for the poor performance of the copper are hypothesized and plans for future work outlined. 11 refs., 9 figs., 4 tabs.
