  • Patent number: 9062954
    Abstract: 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.
    Type: Grant
    Filed: November 7, 2014
    Date of Patent: June 23, 2015
    Assignee: CORVID TECHNOLOGIES
