  • Patent number: 10365070
    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 exhibits a first surface, a second surface opposite to the first surface, and a 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.

  • Patent number: 9869534
    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.
