FAIRPRENE INTEGRAL FUEL TANK SEALING MATERIAL - SWELLING CHARACTERISTICS OF,
Abstract
The swelling characteristics of Fairprene 5570, a Neoprene G. N. synthetic rubber immersed in ten aviation fuels, and ten toluol (aromatic hydrocarbon) - aviation fuel mixtures were measured by volume displacement, weight gain and length increase methods. A relationship was established between these methods. Analine points of the aviation fuels were obtained, and a relationship between the analine point and swelling was established. A field test using the length increase of a ten inch strip of material as a measure of swelling was devised. Equilibrium swelling and the rate of swelling were found to increase with increasing aromatic content of temperature of fuels. Swelling increased as the analine point of the fuel was lowered, and in general the logarithm of the equilibrium swelling varied inversely with the analine point of the aviation fuel. (Author)
