Abstract
A puncture and abrasion resistant, air and water impervious laminated fabric is provided. The laminated fabric includes a woven fabric base layer having warp and weft yarns, with at least 50 percent of the fibers in the warp yarns being formed of high performance material. A first thermoplastic film is bonded by heat and pressure to at least one of the sides of the fabric base layer. The first thermoplastic film is formed of ethylene vinyl acetate. A second thermoplastic film is bonded by heat and pressure to the first thermoplastic film on at least one of sides of the fabric. The second thermoplastic film is formed from either high density polyethylene or low density polyethylene.
