Abstract
Various copper-tungsten shaped charge compacted powder liners have been studied and discussed in this paper based on the produced liner density. Different powder compositions yield different jet characteristics when these liners are used in shaped charge penetration test. Autodyn hydrocode has been implemented to study the effect of the metal powder liner density on the produced jet characteristics. Liners have been produced by both uniaxial pressing and cold isostatic pressing techniques. Liners produced experimentally using uniaxial pressing technique exhibited density variation along the liner height, while those manufactured using cold isostatic pressing are featured by relative uniform density. The former technique with non-uniform density distribution along the liner height has shown efficiency when compared to the latter one of uniform density. The difference in the performance of the two studied liners was confirmed experimentally using static filed testing against rolled homogeneous armour (RHA) targets.
