| 20080237911 | Method to apply multiple coatings to a fiber web - A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials. A first polymeric material is applied onto at least one fibrous substrate, and a second polymeric material is applied onto a support. The fibrous substrate and support are joined, contacting the first polymeric material with the second polymeric material, followed by separating the support from the fibrous substrate, such that at least a portion of the second polymeric material remains on the first polymeric material on the fibrous substrate. | 10-02-2008 |
| 20080241494 | Method to create an environmentally resistant soft armor composite - Fibrous substrates and articles that retain their superior ballistic resistance performance after exposure to liquids such as sea water and organic solvents, such as gasoline and other petroleum-based products. The fibrous substrates are coated with a multilayer polymeric coating including at least two different polymer layers wherein at least one of the layers is formed from a fluorine-containing polymer. | 10-02-2008 |
| 20090025111 | Flexible ballistic composites resistant to liquid pick-up method for manufacture and articles made therefrom - Flexible ballistic resistant composite material that has improved resistance to pick-up of water and other liquids, the composite material comprising a plurality of non-woven fibrous layers. The fibrous layers are formed from a network of high tenacity fibers (aramid fibers, extended chain polyethylene fibers and/or rigid rod fibers). The fibers are embedded in a matrix of a thermoplastic polyurethane resin. Preferably, at least two adjacent fiber layers are oriented in a cross-ply arrangement with respect to each other. Flexible armor, such as body vests, are provided which are formed at least in part from the flexible composite material. | 01-29-2009 |
| 20090053442 | Hybrid Fiber Constructions To Mitigate Creep In Composites - Hybrid fiber constructions having reduced creep tendency. More particularly, twisted, low creep yarns formed by twisting together one or more high strength polyolefin fibers and one or more low creep reinforcing fibers. | 02-26-2009 |
| 20090269583 | High tenacity polyolefin ropes having improved strength - A rope comprising a plurality of high tenacity polyolefin yarns aligned in a substantially uniaxial direction along the length of the rope. The rope yarns are substantially untwisted and are substantially parallel to each other. The yarns are formed from a plurality of fibers aligned in a substantially uniaxial direction along the length of the yarns, with the fibers being substantially untwisted and being substantially parallel to each other. The fibers comprise high tenacity polyolefin fibers. Adjacent yarns are connected together by contact of their respective resin surface coatings. | 10-29-2009 |
| 20090297816 | HIGH PERFORMANCE SAME FIBER COMPOSITE HYBRIDS BY VARYING RESIN CONTENT ONLY - Multi-panel ballistic resistant articles formed from woven and/or non-woven fibrous panels, each panel including varying quantities of a polymeric composition based on the total weight of the fibers and the polymeric composition. The hybrid structures provide excellent ballistic penetration resistance while maintaining a low weight. The ballistic resistant articles may be strategically positioned to dial in different levels of desired ballistic resistance for various applications. | 12-03-2009 |
| 20100015406 | Laminated felt articles - Laminated felt sheets, and assemblies thereof, having utility for impact absorption, ballistic resistance, penetration resistance per se, as well as in spall shields, structural composites and other applications. | 01-21-2010 |
| 20100170386 | SPACED LIGHTWEIGHT COMPOSITE ARMOR - Lightweight, ballistic resistant articles are provided. More particularly, armor structures incorporating two or more spaced apart, ballistic resistant panels, having superior impact and ballistic performance at a light weight. The panels are spaced by air or by an intermediate material. | 07-08-2010 |
| 20100275337 | Helmets for protection against rifle bullets - A helmet shell is formed having an outer section of fibrous layers, a middle section of fibrous layers and an inner section of fibrous layers. The outer section layers contain high tenacity abrasive fibers in a resin matrix. The middle section layers contain high strength polyolefin fibers and are in the form of woven or knitted fabrics with a resin matrix. The inner section layers contain high strength polyolefin fibers and are in the form of non-woven fabrics with a resin matrix. The helmet is lightweight and resists penetration of rifle bullets. | 11-04-2010 |
| 20110049753 | High molecular weight poly(alpha-olefin) solutions and articles made therefrom - A robust process for the continuous preparation of solutions of high molecular weight UHMW PO that is capable of producing strong materials at high production capacity, is conservative of capital and energy requirements, and the articles made therefrom. | 03-03-2011 |
| 20110143086 | ENVIRONMENTALLY RESISTANT BALLISTIC COMPOSITE BASED ON A NITRILE RUBBER BINDER - Ballistic resistant fabrics and articles that retain superior ballistic resistance performance after exposure to liquids such as sea water and organic solvents, such as gasoline and other petroleum-based products. The fabrics are formed from high performance fibers coated with a nitrile rubber binder polymer having an acrylonitrile content of from about 15 wt. % to about 50 wt. %, and are optionally coated with a binder that is a blend of a nitrile rubber and a fluorine-containing material. | 06-16-2011 |
