抄録	This study proposes the novel manufacturing method of adhesively bonded joint with double-sided tapes by following the concept of bi-adhesive bondline. The stress concentration at the ends of the bondline for a single-lap joint can be suppressed by utilizing flexibility of the double-sided tapes. The double-sided tapes also make it easy to control the bondline thickness and to hold the adherends with their stickiness until complete cure. A tensile-shear test of the aluminum/acrylic joint verified that replacing both ends of the 30 mm bondline by the 3 mm double-sided tape improved the maximum load by more than 20%. The observation on the bonded area through the transparent acrylic plate revealed the suppression of the debonding initiation. On the other hand, the aluminum/aluminum joint did not show the significant increase in the maximum load, but suppressed the unstable interfacial debonding. The strain distribution obtained by digital image correlation method proved that the double-sided tape has the same effect of compressive strain generated in the flexible adhesive in bi-adhesive bondline.
