Adhesives are alternative joining techniques which can be used instead of different connecting methods such as bolt, rivet, weld, and solder. Especially the use of adhesives in aviation, space, automotive, building and marine industrials, for which the security of the joints needed, increases gradually. By using adhesively bonded joints, adherents which had different properties and thickness, acquiring regular stress distribution, can be joined more economically and slightly.
The aim of the study is to repair the bonding parts having different notch geometries with adhesives. For this purpose, Aluminum alloy plates have the thickness of 2 mm , the width of 25, 30 and 35 mm, the height of 112,5 mm, and notch geometries with the height of 2, 4, 6 mm and the width of 8 mm on these plates were used, and then these notched samples were fixed with aluminium with the dimensions of 40-25,40-30,40-35. Finally, mechanical behaviour of these samples were examined with experimantal . As a result, it has been observed that failure loads of aluminum alloy plates repaired with patches are higher than unpatched aluminum alloy plates
