    摘要: A multilayered composite fabric which comprises (a) a first fabric comprising non-woven unidirectionally oriented fibers in a first resin matrix, the fibers comprising high tenacity fibers, the first fabric comprising first and second surfaces; and (b) a second fabric comprising multi-directionally oriented fibers optionally in a second resin matrix, the second fabric also comprising high tenacity fibers, the second fabric having first and second surfaces, the first surface of the second fabric being bonded to the second surface of the first fabric thereby forming the composite fabric. Also described is a method of making such fabric wherein the second fabric layer is used as a support during the manufacturing process and is thereafter consolidated into a single structure with the first fabric layer.

    摘要: A ballistic resistant composite material useful in rigid armor applications. The composite material includes at least one consolidated network of high tenacity fibers in a thermoplastic matrix material. The resin is a thermoplastic polyurethane resin that is semi-crystalline at room temperature. The high tenacity fibers have a tenacity of at least about 7 g/d. Prior to consolidation the polyurethane resin matrix material is in an aqueous medium. When dry, the polyurethane matrix material has a tensile modulus (at 100% elongation) of at 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). The ballistic resistant composite material has improved ballistic properties.
