ABSTRACT OF THE DISCLOSURE A flexible sheet material is disclosed for making air cushion vehicle skirts and the like. A molded seamless air cushion vehicle skirt and method of making same are also disclosed. In the method, an uncured, liquid polyurethane is sprayed onto a mold in the shape of a predetermined air cushion vehicle shirt. This forms a first continuous polyurethane layer on which is laid a foraminous substrate made of triaxially woven Kevlar filament material. The substrate is then coated with a second continuous layer of liquid, uncured polyurethane. The polyurethane layers penetrate the substrate and mix together so that when the polyurethane is cured, a continuous molded shirt is formed of material which cannot be delaminated. Parts of the mold may be masked to produce uncoated areas of the substrate. These areas may be later sprayed with liquid urethane to produce permeable sections in the air cushion vehicle skirt. The permeable sections reduce drag when the shirt is mounted on an air cushion vehicle and also prevent undesirable vibration or tramping problems in use.
