Standard Bonded Repairs for Corrosion Damage

Abstract

This report details experiments done to evaluate the effects of intense corrosive action on an area with a bonded repair over corrosion damage. Panels were pre-corroded and repaired using a variety of repair materials. The repaired specimens were then re-exposed to a corrosive environment to determine the effectiveness of the bonded repair in preventing additional corrosion. After re-exposure, evaluation of repaired specimens showed that the bonded repairs provided good protection from the corrosive environment provided the edges were effectively sealed. In addition, Boeing Wedge Test coupons and Single Lap Shear coupons were similarly exposed and re-exposed to a corrosive environment. All samples were well within acceptable tolerances for the adhesive. Effects of corrosion damage on fatigue life will be examined in future work.
