Mechanical behaviour of hybrid welded-bonded joints of 3.7035 titanium alloy and CFRP in thin-walled tubular trusses (opens in new tab)

This study investigates mechanical behaviour and load-bearing capacity of welded, bonded, and hybrid welded-bonded joints made from thin-walled 3.7035 titanium alloy (Grade 2) and carbon fibre-reinforced polymer (CFRP) tubes under quasi-static loading at room temperature. The motivation lies in the aerospace industry, where significant weight savings can be achieved by replacing welded metal frames with bonded or hybrid configurations (by combining metals and composites). A comprehensive expe...
