Abstract
A composite flexible fabric is employed as a covering for an opening of a building, such as a window or door. The composite fabric protects the opening from hurricane force winds and associated flying objects. The composite fabric is formed from at least one layer of a fabric comprised of high tenacity polyolefin fibers and at least one layer of a plastic film. The film is attached to at least one surface of the high tenacity polyolefin fiber fabric. Each of the fabric layer and the film layer are sufficient translucent so as to permit light to enter the opening of the building. The fabric layer provides protection against high wind and impact from projectiles, and the film layer provides an impervious barrier to water, such as wind driven rain. An adhesive layer may be used to enhance bonding between the fabric layer and the film layer.
