ENVIRONMENTAL EXPOSURE OF ADHESIVE-BONDED METAL LAP JOINTS
Abstract
An investigation was started on the relative durability of metal-bonding adhesives when exposed at two sites, Miami, Fla., and the Panama Canal Zone. Twelve sets of lap-joint panels of clad 2024-T3 aluminum alloy respectively bonded with 12 different adhesives, and 1 set of 17-7PH corrosion-resisting steel bonded with another adhesive were prepared for exposures at these two sites and for laboratory-controlled exposure tests. Panels were exposed while stressed in bending and while unstressed. Partial sets of panels are to be removed and tested periodically through 3 years of exposure. This intial report summarizes the preparation of the test panels, data from the laboratory-controlled exposures and, for some of the adhesives, data after 1 year of natural environmental exposures.
