Abstract
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.
Claims20
A ballistic resistant material comprising:
- a first panel and a second panel, each comprising a plurality of fibrous layers, said plurality of fibrous layers being consolidated;
- each of the fibrous layers comprising a plurality of fibers, said fibers in each of said fibrous layers being the same in each panel and having a tenacity of 7 g/denier or more and a tensile modulus of 150 g/denier or more;
- each of said fibers having a surface, wherein the surfaces of the fibers of said first panel are coated with a polymeric matrix composition;
- and wherein the second panel comprises fibers that are not coated with a polymeric matrix composition.

A ballistic resistant material comprising, in order:
- a) a first panel comprising a plurality of fibrous layers, said plurality of fibrous layers being consolidated;
- each of the fibrous layers comprising a plurality of fibers, said fibers having a tenacity of 7 g/denier or more and a tensile modulus of 150 g/denier or more;
- each of said fibers having a surface, and the surfaces of said fibers being coated with a polymeric matrix composition;
- and
- b) a second panel attached to the first panel, which second panel is different than the first panel, and which second panel comprises a plurality of fibrous layers, said plurality of fibrous layers being consolidated;
- each of the fibrous layers comprising a plurality of fibers, said fibers having a tenacity of 7 g/denier or more and a tensile modulus of 150 g/denier or more;
- each of said fibers having a surface, and the surfaces of said fibers being coated with a polymeric matrix composition;
- and
- said first panel containing a greater percentage by weight of the polymeric matrix composition in the first panel, based on the total weight of the first panel, than a percentage by weight of the polymeric matrix composition in said second panel, based on the total weight of the second panel;
- and
- c) one or more additional panels attached to said second panel, wherein at least one of said additional panels comprises fibers that are not coated with a polymeric matrix composition;
- wherein said one or more additional panels comprises a plurality of fibers having a tenacity of 7 g/denier or more and a tensile modulus of 150 g/denier or more;
- wherein said first panel is positioned closer to a potential ballistic threat relative to the second panel.

A ballistic resistant material comprising:
- a first panel comprising a plurality of fibrous layers, said plurality of fibrous layers being consolidated;
- each of the fibrous layers comprising a plurality of fibers, said fibers having a tenacity of about 7 g/denier or more and a tensile modulus of about 150 g/denier or more;
- each of said fibers having a surface, and the surfaces of said fibers being coated with a polymeric composition;
- and
- a second panel attached to the first panel, which second panel is different than the first panel, and which second panel comprises a plurality of fibrous layers, said plurality of fibrous layers being consolidated;
- each of the fibrous layers comprising a plurality of fibers, said fibers having a tenacity of about 7 g/denier or more and a tensile modulus of about 150 g/denier or more;
- each of said fibers having a surface, and the surfaces of said fibers optionally being coated with a polymeric composition;
- wherein the first panel and the second panel are juxtaposed with each other in a non-bonded array;
- and
- wherein when the surfaces of the fibers of the second panel are coated with a polymeric composition, said first panel contains a greater percentage by weight of the polymeric composition in the first panel, based on the total weight of the first panel, than a percentage by weight of the polymeric composition in said second panel, based on the total weight of the second panel.
