Abstract:
A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.
Abstract:
Woven multi-layer fabrics and/or rigid or semi-rigid composite panels incorporating one of more woven multi-layer fabrics all as generally and specifically described herein.

Abstract:
A ballistic resistant article includes at least one consolidated composite, wherein the at least one consolidated composite includes a layer A and a layer B bonded to one another. Each layer A and B exhibitsa first surface,a second surface opposite to the first surface, anda cross-section extending from the first surface to the second surface and includes a network of fibers having a strength of at least 800 mN/tex (1100 MPa), and the fibers in each layer A and B are impregnated with a matrix material. The matrix material is distributed along the cross-section of each layer in a concentration gradient in which the concentration starts with a maximum value on the first surface, decreases along the cross-section and reaches a minimum value on the second surface. The matrix material includes a mixture of a polychloroprene, and a random copolymer of vinyl chloride and an acrylic ester.
Abstract:
A ballistic resistant article is provided along with a process to manufacture the article. The ballistic resistant articles includes at least one consolidated composite, wherein the at least one consolidated composite includes at least two layers, each layer includes a network of fibers, the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07, the fibers in each layer are impregnated with a matrix material, and each consolidated composite has a front surface and a rear surface. In the ballistic article, at least the front surface of each consolidated composite is powder coated with partly molten and solidified powder particles to form a powder coated surface.

Abstract:
A fiber processing system includes a fiber spreader that has a spreader bar that extends in a lengthwise direction between first and second ends. The spreader bar carries at least one radiused surface between the first and second ends. At least one mechanical vibration device is operable to vibrate the spreader bar. The at least one mechanical vibration device is connected to input mechanical vibration into the spreader bar at a location between the first and second ends. A method for spreading at least one fiber bundle includes moving at least one tensioned fiber bundle over a radiused surface of the spreader bar. During the moving, mechanical vibration is input into the spreader bar at a location between the first and second ends, to transversely spread and flatten the at least one tensioned fiber bundle.
