  • Publication number: 20110256789
    Abstract: A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials. A first polymeric material is applied onto at least one fibrous substrate, and a second polymeric material is applied onto a support. The fibrous substrate and support are joined, contacting the first polymeric material with the second polymeric material, followed by separating the support from the fibrous substrate, such that at least a portion of the second polymeric material remains on the first polymeric material on the fibrous substrate.

  • Publication number: 20110219943
    Abstract: A multilayered composite fabric, the composite fabric comprising a first fabric comprising first and second non-woven unidirectionally oriented fiber layers. Each of the fiber layers is in a resin matrix and the fibers comprise high tenacity fibers. The fibers in the two fiber layers are disposed at an angle with respect to each other. The composite fabric includes a second fabric comprising multi-directionally oriented fibers optionally in a resin matrix. The second fabric also comprises high tenacity fibers.
