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. The first and second fabrics are bonded together to form the composite fabric, which has improved ballistic resistant properties. Plastic films may be adhered to one or both outer surfaces of the first fabric and can serve as the bonding agent between the two fabrics. Also described is a method of making a composite fabric.
