Abstract: A liner for a shaped charge including an inner layer made of a material having a density below 10.5 g/cm3, and an outer layer made of a material having a density below 2.0 g/cm3, wherein the outer layer is formed directly on the inner layer. In a first state, both the inner layer and the outer layer are compressed towards the symmetry axis (x) of the liner, thereby forming a projectile. In a second state, the inner layer forms a penetration jet of the projectile and the outer layer forms a slug of the projectile. The melting point of the outer layer is above 100° C. The invention also concerns a shaped charge including the liner, a method for manufacturing the liner and a method for detonation of the shaped charge.

Abstract: A shaped charge assembly, comprising a casing and a liner, is disclosed. The liner includes a first longitudinal section connected to the casing, a second longitudinal section having the shape of a truncated cone wherein the truncated end thereof is directly connected, or connected by means of an intermediate longitudinal section, to the first longitudinal section. The second longitudinal section is at its base end directly connected to a third longitudinal section. The third longitudinal section is in the shape of a cone, an ogival or a hemisphere.
