Abstract:
1. A ballistic resistant article formed from a ballistic resistant material, the ballistic resistant material comprising: 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 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 composition; and c) said first panel containing 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; and d) at least one additional panel attached to the first panel, to the second panel, or to both the first panel and to the second panel, the at least one additional 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, the surfaces of said fibers being coated with a polymeric composition, and wherein the said second panel contains a greater percentage by weight of the polymeric composition, based on the total weight of the second panel, than a percentage by weight of the polymeric composition in said at least one additional panel, based on the total weight of the at least one additional panel.
