Abstract
In this study, we have suggested the new joint configuration, which has a curved surface at a bonded part, and we have named it an "adhesively waved butt joint". Static tensile experiments to clarify the joint strength were carried out, using epoxy structural adhesive. While the adhesive layer in the longitudinal direction was examined on a basis of 0.1 mm in thickness, effects of adhesive thickness and adherend material on joint strength were examined in the experiments, where the adhesive thickness was changed from 0.1 to 0.05, 0.2 and 0.5mm, with the three kinds of adherend materials-aluminum alloy, mild steel and brass. As a result, load bearing property of "adhesively waved butt joint" proved to rise higher than the conventional butt joint. Furthermore, the joint strength increased as the adhesive thickness decreased. However, no regularity was recognized between the joint strength and rigidity by the adherend material.
