Abstract

In this paper, static tensile experiments to clarify the joint strength for adhesive waved butt joints with dissimilar adherends were carried out, using epoxy structural adhesive. In addition, effects of adhesive thickness and combination of adherend material on joint strength were examined in the experiments, where the adhesive thickness was changed from 0.05 to 0.1, 0.2, 0.5 mm, with the three kinds of combination of adherend materials "aluminum alloy A5052-mild steel SS400, aluminum alloy A5052-brass C3604, mild steel SS400-brass C3604". It proved that the case of similar adherend shows tendency in opposite for strength characteristics, from the result that the joint strength increases as the adhesive thickness increases in case of dissimilar adherend. The joint strength of specimen using brass C3604 as material of one side adherend proved to be the highest in the three kinds of combination of the adherend materials.
