摘要:
Flexible ballistic resistant composite materials are described, having any of a number of important properties, or a combination of properties, including flexibility, comfort, weight, and/or ballistic performance. Representative composite materials comprise a plurality of fibrous layers, such as non-woven fibrous layers, with these fibrous layers comprises fibers (e.g., a network of fibers) having a tenacity of at least about 35 g/d and a tensile modulus of at least about 1200 g/d. Representative fibers include, for example, high tenacity poly(alpha-olefin) fibers. The fibrous layers also comprise a polymeric matrix deposited on the fibers. Advantageously, such composite materials may have an average total areal density per fibrous layer from about 16 g/m2 to about 350 g/m2, and often from about 16 g/m2 to about 300 g/m2, in addition to meeting flexural rigidity and/or stiffness criteria as described herein.

摘要:
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.
摘要:
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.
