Abstract:

We have evaluated seven candidate nitrile-coated fabrics for use in collapsible fuel storage containers that we received from four suppliers, Bulk Liquid Storage Systems BLSS, Avon Engineered Fabrications AEF, Berg Inflatable Systems BIS and Dunlop Corporation. Four of the materials BLSS, BergReeves, AEFReeves, and AEFArcher met the MIL-PRF-32233 JP-8 fuel diffusion requirement of 0.06 ozftexpn 224h. The JP-8 diffusion rates for the remaining three materials did not meet the military specification. All materials performed well in peel adhesion testing when conditioned with fuels however, when conditioned with water at elevated temperatures a major decrease in strengths are observed. The Dunlop fabric seam performed poorly retaining only 20 of its original peel strength. The reduction was only 50 when extraction with JP-8 was performed before water conditioning.
