摘要： This disclosure describes fabric and a method for making fabric, for use in a flexible pressure vessel or other fabric structures, which has an unbalanced woven construction and has a balanced or nearly balanced modulus of elasticity for the end-use conditions of this fabric. Unbalanced woven fabrics that do not have balanced properties produce unequal stretching and are susceptible to premature failure. The present invention of unbalanced woven fabric construction with balanced mechanical properties such as modulus of elasticity can be used to optimize fabric strength, mass, volume, and performance characteristics and also reduce manufacturing costs for various fabric structure applications. Balanced mechanical properties for the fabric structure are achieved by altering the force of the fabric by increasing or decreasing the number of yarns in a particular direction of the fabric, by changing the strain during stretch of the fabric, or by alternative weaves of the fabric.

摘要： An apparatus and method for making a low cost, self-venting, inflatable protective cushion of simple and structurally efficient design with a shape and construction that optimizes the cushion's ability to withstand inflation pressures and impact when deployed which includes a sheet (20) of material woven of less than 420 denier yarn defined by at least one fold line (22) and a plurality of flap portions (23), each flap portion having a base edge (24) corresponding to a fold line (22) and at least two side edges (25) each extending outwardly from the base edge (24) and ultimately converging to meet each other, the flap portions (23) being folded at the fold lines (22) and being joined at corresponding side edges (25) to define an inflatable chamber. The inflatable protective cushion and method for making same may further include a lightweight, low permeability, fabric that optimizes the cushion's ability to whithstand inflation pressures and impact when deployed and minimizes the packed volume of the cushion when stored.
