Abstract:
A ballistic fabric (20) having unidirectional ballistic resistant yarns (22, 24) in at least two layers. The layers are at 90° ± 5° with respect to each other. The ballistic resistant yarns are stabilized by being woven in a second fabric formed of yarns (26, 28) having a substantially lower tenacity and tensile modulus than the ballistic resistant yarns.
Abstract:
A multi-layer woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The cover factor of at least one of the layers is selected so as to inhibit penetration by non-ballistic threats
Abstract:
A fiber processing system includes a fiber spreader that has a spreader bar that extends in a lengthwise direction between first and second ends. The spreader bar carries at least one radiused surface between the first and second ends. At least one mechanical vibration device is operable to vibrate the spreader bar. The at least one mechanical vibration device is connected to input mechanical vibration into the spreader bar at a location between the first and second ends. A method for spreading at least one fiber bundle includes moving at least one tensioned fiber bundle over a radiused surface of the spreader bar. During the moving, mechanical vibration is input into the spreader bar at a location between the first and second ends, to transversely spread and flatten the at least one tensioned fiber bundle.

Abstract:
Described are protective and/or ballistic resistant composites wherein the resin matrix comprises between 15% and 20% of the total weight of the composite. Also described are protective and/or ballistic resistant composites comprising one or more layers of fabric bound to one or more layers of a machine-direction oriented film that exhibit excellent abrasion resistance. The articles include those made using woven and/or non-woven fabrics such as unidirectional fabrics and gradient resin matrices. Methods for producing ballistic-resistant articles using woven and/or non-woven fabrics and machine direction oriented film are also provided.
Abstract:
A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yams is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.
