Abstract: A method of manufacturing a fuel resistant material for use in collapsible fuel tanks that includes preparing a spreadable rubber mixture; spread coating the rubber mixture onto a fabric substrate; drying the rubber and fabric to create a primed fabric; applying a first rubber film on a first surface and a second rubber film on a second surface of the primed fabric, the first rubber film being applied at a thickness greater than a thickness on the second rubber film on the second surface to create an off balanced fabric; applying a third rubber film to the second surface to a produce a thickness substantially equal to that of the first surface to create a final coated product; and curing the final coated product.
