Abstract

High strength/density ratio and toughness, ease of manufacture, long term performance, joinability by riveting and welding, and recyclability, justify the long period of preeminence of aluminum as the main material for structures of aircraft, Merati [1]. Facing competition from composite fiber reinforced plastics, aluminum producers are trying to reduce weight and improve performance developing new alloys. In parallel, joining techniques as laser beam welding (LBW) or friction stir welding (FSW) originate integral structures, with manufacturing weight and part count advantages vis a vis traditional riveting. The dominance of Al was challenged with the Boeing 787 with increased use of titanium alloys and almost 50% by weight of aircraft structure constructed from composites, and by Airbus with even more 53% of structure composites weight in the A350 XWB.
