Abstract

This paper examines the effects of accelerated weathering on samples of aircraft covering prepared using the Grade-A cotton with Randolph dope, Ceconite with Randolph dope, Cooper Superflite 11, Air-Tech Coatings, and Stits Poly- Fiber processes. The results indicate that although Air-Tech and Superflite processes were the heaviest, both maintained excellent gloss retention over the accelerated weathering cycle. Ceconite with Randolph dope was the least stable in yellowing degradation while Stits was the best performer. Strength degradation was most pronounced in the Superflite process. Thermal stress testing showed all processes exhibited heat and flame resistance loss due to weathering.
