The armor assemblies may include multiple layer arrangements of the solid armor plates that provide substantially complete coverage of a surface when the multiple discontinuous layers are combined. Ropes or other coupling elements may be used to horizontally connect plates together within the same discontinuous layer of armor plates and ropes may also be used to vertically connect plates in different armor layers. In some example, the armor assembly may be highly flexible and breathable to provide body armor that may be comfortably worn. In some examples, armor assemblies may be adapted for use as vehicle armor or other armor applications.Type: ApplicationFiled: April 14, 2010Publication date: July 14, 2011Inventor: Young-Hwa Kim

Publication number: 20110107904Abstract: The armor system according to the present invention also exploits synergistic multi-layering to provide different properties as a function of depth within a sandwich panel. Various embodiments of the invention include a combination of composite sandwich topology concepts with hard, strong materials to provide structures that (i) efficiently support static and fatigue loads, (ii) mitigate the blast pressure transmitted to a system that they protect, (iii) provides very effective resistance to projectile penetration, and (iv) minimizes shock (stress wave) propagation within the multi-layered armor sandwich structure. By using small pieces of highly constrained ceramic, the concept has significant multi-hit potential.Type: ApplicationFiled: August 15, 2008Publication date: May 12, 2011Applicant: UNIVERSITY OF VIRGINIA PATENT FOUNDATIONInventors: Douglas T.

Publication number: 20110030543Abstract: An armor module for protecting a surface against an explosively formed projectile (EFP) threat is provided. The armor module is configured for mounting on the surface and comprises at least one armor assembly having a hard layer disposed facing the threat and being configured to fragment the EFP, thus forming residuals of the original EFP threat; a unidirectional fiber layer disposed behind the hard layer; and a catcher layer behind the unidirectional fiber layer, the catcher layer being made of a material exhibiting a level of ballistic protection such that a layer of the material being of the same thickness as the unidirectional fiber layer absorbs at least 20% more energy than is the unidirectional fiber layer for the same threat.Type: ApplicationFiled: December 31, 2009Publication date: February 10, 2011Applicant: PLASAN SASA LTD.Inventors: Moshe RAVID, Amit VIESEL

Publication number: 20100275767Abstract: A transparent armor laminate system includes a plurality of sub-stacks separated by an interlayer. The sub-stacks include a plurality of layers including a glass ceramic front strike-face layer, a backing layer comprising a spall-resistant material, and at least one glass layer laminated between the strike-face and backing layers. The interlayer isolates cracks between sub-stacks, and may include an isolating material such as a polymer, gas, or liquid. The laminate system offers improved performance with reduced weight over conventional all-glass or all-glass-ceramic transparent armors.Type: ApplicationFiled: August 27, 2008Publication date: November 4, 2010Inventors: Linda Ruth Pinckney, Huan-Hung Sheng, Steven Alvin Tietje, Jian-Zhi Jay Zhang
