Abstract
A flexible fragmentation sleeve for use with a non-fragmenting explosive device is provided. The flexible fragmentation sleeve comprises a flexible cylindrical wall extending between opposing first and second ends along a longitudinal axis. The cylindrical wall includes an inner liner and an outer liner concentric to the inner liner. A first set of coupling elements extend parallel to the longitudinal axis of the cylindrical wall, and couple the inner liner with the outer liner. A second set of coupling elements extend circumferentially along the cylindrical wall. The second set of coupling elements is substantially perpendicular to the first set of coupling elements, and couple the inner liner with the outer liner. A plurality of pockets is defined intermediate the inner liner and the outer liner, and intermediate the first set of coupling elements and the second set of coupling elements. The flexible fragmentation sleeve of the illustrative embodiment further includes a plurality of fragmentation members. At least one fragmentation member is illustratively received within each pocket.
