Abstract

An investigation was made of the relative durability of metal-bonding adhesives in exterior exposure at two sites, Miami, Fla., and the Panama Canal Zone. Twelve sets of lap-joint panels of clad 2024-T3 aluminum alloy bonded with 12 different adhesives, and one set of 177PH corrosion-resisting steel bonded with another adhesive, were exposed at these two sites. Panels were exposed while stressed in bending and while unstressed. Sets of panels were removed and tested periodically through 3 years of exposure. In addition, several short-term laboratory exposure conditions were used to determine whether such tests might provide information similar to the long-term exposure. In general, stressed specimens decreased in strength more than the unstressed specimens, Florida exposure caused a greater loss in strength than the Panama exposure, and exposure to the weather was more severe than laboratory exposure cycles.
