Airbus A350 made from material titanium
Design
Airbus expected 10% lower airframe maintenance compared with the original A350 design and 14% lower empty seat weight than the Boeing 777. Design freeze for the A350-900 was achieved in December 2008.
The airframe is made out of 53% composites: CFRP for the empennage (vertical and horizontal tailplanes), the wing (centre and outer box; including covers, stringers, and spars), and fuselage (keel beam, rear fuselage, skin, and frame); 19% aluminium and aluminium–lithium alloy for ribs, floor beams, and gear bays; 14% titanium for landing gears, pylons, and attachments; 6% steel; and 8% miscellaneous. The A350's competitor, the Boeing 787, is 50% composites, 20% aluminium, 15% titanium, 10% steel, and 5% other.
