J191034 Experimental Study of Cutting and Breakup Performance by Linear Shaped Charge

Spall behavior of single and multi-layered hybrid composite structures behind armor was investigated by using shaped charge. Firstly, spall cone angles of Aluminum 5083-H116 and rolled homogeneous armor (RHA) steel as base armor materials were determined without any composite to select base armor. The single and multi-plates composite samples were produced by using S2 glass plain fabric, Kevlar plain fabric and hybrid Carbon-Kevlar twill fabric and epoxy resin system. After that, composite samples were placed behind the selected base armor plates with different distance in between them. The changes of spall cone angle, spall diameter, and penetrated area after shaped charge penetration were determined and analyzed in terms of both material configuration and distance behind the armor plates. As a result, increasing the behind armor distance reduces the jetting area and thus spall distribution decreases. In addition, it can be recommended to use hybrid 1 and 50 mm behind armor distance by evaluating both spall distribution and in-vehicle volume restriction.

In this paper, a novel linear shaped charge (LSC), called a bi-apex-angle linear shaped charge (BLSC), has been designed to investigate the improvement of penetration performance. Compared with a traditional single-apex-angle LSC, a BLSC, which consists of a small-apex-angle liner and a large-apex-angle liner, has been investigated by depth-of-penetration (DOP) test. The results show that the penetration depth of BLSC is 29.72% better than that of an ordinary LSC. An Eulerian method is applied to simulate the entire process of jet formation, as well as penetration on a #45 steel target. The effectiveness of the Eulerian model is demonstrated by the good agreement of the computational results with experimental observations. Furthermore, the numerical simulation is developed to investigate the influence of liner thickness, explosive type, combination of small and large apex angle, ratio of small to all apex angle liner, and standoff distance on the penetration performance of BLSCs. The suggested work and results can provide a guide and reference for the structural design of BLSC.
