Patent ID: 7919418

Claim:
A flexible ballistic resistant composite material having improved flexibility, said composite material comprising a plurality of non-woven fibrous layers, said fibrous layers comprising a network of high tenacity poly(alpha-olefin) fibers having a tenacity of at least about 35 g/d and a tensile modulus of at least about 1200 g/d, said fibers being in a matrix comprising a block copolymer of a conjugated diene and a vinyl aromatic monomer deposited on said fibers as an aqueous composition, said composite having a total areal density equal to or less than about 100 g/m 2 and a stiffness of less than about 2.5 pounds (1.14 kg) for a two layer structure of said composite, and a total areal density equal to or less than about 190 g/m 2 and a stiffness of less than about 3.0 pounds (1.36 kg) for a four layer structure of said composite.
