In a disclosed example, at least two rigid layers have at least one ballistic material layer between them to provide a rigid armor material composition.Type: GrantFiled: July 14, 2004Date of Patent: April 29, 2008Assignee: Hamilton Sundstrand CorporationInventors: W.

Publication number: 20080087161Abstract: A body armor assembly includes a plurality of rigid tiles that are supported in a manner to provide movement and flexibility while still providing the protection of rigid armor. In a disclosed example, a tile holder maintains a plurality of tiles in a selected alignment. The tile holder maintains a minimum overlap dimension between adjacent tiles. Some of the tiles are maintained by the tile holder in a manner that allows for the overlap dimension to increase beyond the minimum overlap dimension. In a disclosed example, at least two rigid layers have at least one ballistic material layer between them to provide a rigid armor material composition.Type: ApplicationFiled: July 14, 2004Publication date: April 17, 2008Inventors: W.

Patent number: 7340779Abstract: An article is disclosed to protect a wearer from spike and ballistic threats that is made from a spike resistant panel and a ballistic resistant panel. Each panel is made from flexible fabric layers. The fabrics in the spike resistant panel are made from first yarns having a linear density of from 50 to 600, with a plurality of filaments. There are 40 to 100 first yarns per inch in both the warp and fill directions. The fabrics in the ballistic resistant panel are made from second yarns having a linear density of from 100 to no more than 840 denier with a plurality of filaments, which provide from 20,000,000 to no more than 90,000,000 filament crossovers per square inch.Type: GrantFiled: July 1, 2003Date of Patent: March 11, 2008Assignee: E.I. du Pont de Nemours and CompanyInventor: Minshon J.
