Abstract:

The purpose of this research was to develop new and improved polymeric coatings for electrical wires which are stable to temperatures above 500 degrees F up to 800 degrees F for use on future high speed aircraft and missile systems. Pyrrone, perfluoroalkylenetriazine, silicone carborane, BBB, polyphenylene, polyimide, polyphenylsilane, carborane modified PBI, and polyxylylene were investigated. Pyrrone and polyimide were found to be excellent adhesives for Kapton polyimide film. Pyrrone, perfluoroalkylenetriazine and silicone carborane had very good dielectric properties. A new cure process for perfluoroalkylenetriazine elastomer was discovered which functions at ambient temperature or higher.
