Its fuselage is constructed entirely from carbon fibre, but also has a greater strength to weight ratio than traditional aircraft materials such as aluminum (the structure of the Eurofighter Typhoon and Boeing 787 Dreamliner are also made significantly out of it). The only significant metal component is the wing spar, running through the middle and reinforcing the wings.
