Abstract: One or more aspects of the present disclosure relate to a method of at least partly manufacturing a liner for a linear shaped charge. The method can include coating each of a plurality of metal particles with a non-metal, to form a plurality of coated spherical particles; mixing, without a solvent, the plurality of coated spherical particles with a polymer binder and at least one of: a filler, a dry lubricant, or a wet lubricant, until a flexible material is formed with the plurality of coated spherical particles dispersed homogeneously in the polymer binder and the flexible material has a mass of at least 5,700 kg per cubic meter volume of the flexible material; and at least partly forming a liner for the linear shaped charge from the flexible material.

Abstract: One or more aspects of the present invention relate to a linear shaped charge comprising an explosive element, a liner, a face for application to a target object and a space between the liner and the face, the liner being arranged for projection through the space, towards the face, when the explosive element is detonated, and the explosive element and the liner having a V-shaped cross section, the liner lying in a groove of the V-shaped cross section of the explosive element, the liner having a length L of a side furthest from the face and the liner having a thickness T taken perpendicular to said length L, wherein an angle ? of an apex of the liner nearest the face is 101.5 to 106.5 degrees, and a stand-off distance SD between the face and a point of the liner nearest the face is 0.99 S to 1.21 S, S being a distance, parallel the stand-off distance SD, between the point of the liner nearest the face and the apex of the liner nearest the face.

Abstract: One or more aspects of the present invention relate to a shaped charge, including a linear shaped charge comprising an explosive element, a liner, a face for application to a target object and a space between the liner and the face, the liner being arranged for projection through the space, towards the face, when the explosive element is detonated, wherein the linear shaped charge comprises at least one film between the liner and the face. The invention further relates to an element for a shaped charge and a method of modifying a shaped charge.
