Experimental Study on the Effect of Buffer Layer on the Explosive Drive of Reactive Fragment

Abstract In order to study the influence of buffer layer on explosive drive reactive fragment, for fragment warhead same structure, static explosion test and break-through target method were used integrity with several different thickness silicone rubber layers. The initial velocity was measured, its variation law analyzed. results show that increase layer, fragments increases. When is 2 mm, rate zero, when greater than 8 0.85. difference in small, mainly because decreases loading ratio decreases; has a significant effect reducing k=0.83 can be modified Gurney formula estimate layer.
