Development of Rain-Erosion-Resistant Coatings for High-Speed Aircraft
Abstract
This search for new, thermally stable, rain-erosion resistant coatings for the radomes and leading edges of high-speed aircraft was concerned mainly with developing tough elastomers that cure at room temperature and that resist heat, solvents, and weather. We have prepared two new types of elastomers that are promising: silphenylene-siloxanes, and hexafluoroacetone-alkylene-silphenylenes. Both cure at room temperature, and both have good thermal stability. In their present states of development, the silphenylene-siloxanes have better tensile properties, and the hexafluoroacetone-alkylene-silphenylenes have greater fuel resistance. Both require further development of the polymerization processes to achieve higher molecular weights and of the curing methods to improve tensile properties.
