Abstract: In this report, we compare seven candidate materials for use in collapsible fuel storage tanks. The nitrile composites all consisted of a nylon-woven fabric coated with nitrile rubber on both sides. We evaluated the permeation behavior of these fabrics when challenged with three military different fuels: Jet Propellant 8 (JP-8), diesel fuel, and the American Society for Testing and Materials (ASTM) Reference Fuel B. It was found that the permeation rates for both the JP-8 and diesel fuels were very similar for all nitrile-coated fabrics. When the ASTM Ref Fuel B is used, a significant increase in the permeation rate is observed for five of the candidate fabrics: the Bell Avon, Dunlop, Eng Fabrics, AmFuel, and Reeves fabrics. However, the Zodiac and Pronal nitrile-coated fabrics exhibited only a small increase in permeation rates. This was attributed to a Teflon-like membrane located on the interior side of the coated fabric. When the temperature is raised to 160 °F, the permeation rates increase by over an order of magnitude for JP-8 and diesel fuels, and by a factor of six for the ASTM Ref Fuel B.
