Graded property barriers for attenuation of shock

摘要

A barrier for reduction of a shock wave. The barrier has a spatially graded structure in which a density of the structure varies across a thickness thereof. The graded structure includes a polymer having hollow containers dispersed in the polymer to provide the density of the graded structure. The barrier can be included in at least one of 1) an explosive device, 2) a war head, 3) a demolition charge, and 4) an explosive containment. These devices have an exterior housing and at least one partitioned segment inside the housing with the partitioned segment including the barrier for reduction of the shock wave. Partitioned sections of the explosive devices are selectively or in total detonated.

1. An explosive device comprising:
an exterior housing; partitioned segments inside the housing, at least one of which is filled with an explosive material; and a partition wall separating the segments, wherein the partition wall comprises, a spatially graded structure in which a density of the structure varies across a thickness thereof, said structure including a polymer having hollow containers dispersed in the polymer to vary said density of said graded structure, and a selective fuzing scheme wherein the segments filled with the explosive material are selectively initiated.
