Abstract

The Dripless Bubbler technique [1–4] has demonstrated in both laboratory and field trials the ability to identify adhesive disbonds and quantify the metal loss due to corrosion in aircraft fuselage structures. In the latest round of field trials, this technique was successfully applied to aid in characterizing exfoliation corrosion around fasteners in thick wing skins (0.190 – 0.500 inches). In two Beta-site tests, the technique was used to identify delaminations, verify ply drop-offs and evaluate repairs in aircraft composite structures such as rudders, spoilers and flaps.
