Method for the multimaterial construction of shaped-charge liners

A shaped charge device having vertical layering comprising:

• a cylindrical housing having a closed end, an open end and a vertical axis;
• an explosive charge contained within said housing, said charge having a cavity formed at the open end of said housing, said cavity symmetric about said vertical axis;
• a vertically layered liner lining said cavity and contacting said charge;
• said liner comprising a plurality of segments;
• said plurality of segments each having a first, second and third surface, said first surface contacting said charge, said second surface and opposed to said first surface and facing said cavity, and said third surface only contacting an adjacent segment, said third surface being flat in any cross section taken parallel with said vertical axis;
• wherein a plane passing through said liner and parallel to said liner's axis of symmetry intersects only one of said liner segments;
• means located at the closed end of said housing for detonating said explosive charge whereby detonation of said explosive charge causes said liner to form a jet comprised of a plurality of said segments.
