Abstract: Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

Abstract: A non-lethal, sabot-deployed blast shield mitigates a suicide bomber by wrapping around the bomber and positioning a plurality of protective layers over an explosive device to absorb emitted heat, shock waves, and projectiles if the device is detonated. Stand-offs such as inflatable beams or pillows provide break-away zones between the protective layers, allowing some layers to expand to a point of failure and absorb the maximum possible energy. Inner layers absorb shock waves and heat. One or more outer layers resist projectile penetration. Protective layers can be positioned on opposing sides of a suspect in case two explosive devices are present. Shields can deploy with sufficient energy to knock down a bomber. In embodiments, a plurality of shields can be applied without interference therebetween. In some embodiments, a round shield includes bolas which spread the shield in flight in a cast-net dynamic and wrap around the suspect for shield attachment.

Abstract: This invention is a novel system for blast protection. It consists of lightweight, sectional or continuous barriers made of a novel blast resistant fiber reinforced polymer resin matrix composite, which may be fabricated on site. The barriers are lightweight and thin enough that they may be used in many spaces where barriers made from conventional construction materials are impossible, impractical, or undesirable. The novel barriers of this invention have the additional advantage of allowing for aesthetically appealing and architecturally harmonious designs. In order to minimize weight, the barriers may be designed such that the cross section varies with height, providing adequate resistance in areas of high blast loading, but allowing for thinner cross sections in regions of lowering load.
