    摘要： A ballistic resistant article and a method of its manufacture are provided. The article comprises at least one consolidated composite, wherein the at least one consolidated composite comprises 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, each layer A and each layer B comprises a network of fibers having a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07, and the fibers in each layer A and B are impregnated with a matrix material, characterized in that the matrix material is distributed along the cross-section of each layer in the shape of a concentration gradient, wherein the concentration starts with a maximum value on the first surface, so that the first surface is rich in matrix material, decreases along the cross-section and reaches a minimum value on the second surface, so that the second surface is poor in matrix material, and the matrix material comprises a mixture of 75 to 95 wt.% of a polychloroprene, and 5 to 25 wt.% of a random copolymer of vinyl chloride and an acrylic ester based on a weight of the mixture.

    摘要： A multi-layer ballistic woven fabric (10) , including an upper woven layer(11) having upper warp yarns (12) and upper weft yarns (14) that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer (13) having lower warp yarns (15) and lower weft yarns (17) that are interwoven together, and a plurality of securing yarns (22), each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns (10) is woven underneath a first lower weft yarn (17), then above a second upper weft yarn (14) adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric (10) is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.
