Patent ID: 6945155

Claim:
An armor system comprising a first pliable, cut resistant fibrous ayer and a second pliable layer substantially coextensive with said first layer, the first layer being arranged to receive an impact from a projectile prior to the second layer and engaging the projectile to slow its velocity, the second layer dissipating the incoming energy of the impact to resist complete penetration of the second layer by the projectile, both of said first and second layers comprising networks of fibers having a tensile modulus of at least about 200 g/d, and an energy-to-break of at least about 8 J/g and a tenacity equal to or greater than about 10 g/d, the networks of the first layer having a different structure from the networks of the second layer, wherein the first layer comprises a plurality of nonwoven networks of oriented fibers and the second layer comprises an uncoated nonwoven network of randomly oriented fibers, and wherein said fibers are selected from the group consisting of polyolefin fiber, polyvinyl alcohol fibers, aramid fibers, polyacrylonitrile fibers, liquid crystalline fibers and mixtures thereof.
