This program investigated state-of-the-art adhesives, adhesive primers, surface treatments, and coatings to determlne, through durability testing, a system that could be used to adhesively bond a primary aircraft structure. Test methods were also evaluated. Previous work indicated cyclic-stressed testing in hostile environments and, specifically, high moisture environments reduced the life and durability of a given adhesive system over the same system load to the same level at constant stress. Conclusions include: Stressed durability testing is required to determine if a given surface treatment is durable; Normal industry accepted processing tolerances on surface treatments are too wide to produce consistently durable bonded joints; Handling of surface treated details must be designed to prevent mechanical damage and contamination; Phosphoric acid anodize process was the surface treatment most tolerant to processing variations and inspectable; Adhesive primers from different suppliers demonstrated a large variation in environment resistance and corrosion protection capabilities; The type of carrier used in adhesive films has a large effect on the moisture resistance of the adhesives; and Cyclic stressed testing ln a hostile environment is necessary to determine the optimum adhesive durability.
