Patent ID: 8256019

Claim:
A ballistic resistant composite material useful in rigid armor applications, said composite material comprising at least one consolidated network of high tenacity fibers in a thermoplastic matrix material, said thermoplastic matrix material comprising a thermoplastic polyurethane resin that is semi-crystalline at room temperature, said high tenacity fibers having a tenacity of at least about 7 g/d, wherein prior to consolidation said matrix material comprises said polyurethane resin in an aqueous medium, said polyurethane matrix material when dry having a tensile modulus (at 100% elongation) of at is least about 500 psi (3.45 MPa), a tensile modulus (at 300% elongation) of at least about 500 psi (3.45 MPa), and, an ultimate tensile strength of at least about 2000 psi (13.78 MPa).
