Which section of the Airbus A350 is made completely from carbon-fiber-reinforced polymer?

The fuselage and wings of the Airbus A350 are made completely from carbon-fiber-reinforced polymer (CFRP), which is a key feature of this aircraft's design. The use of CFRP in these sections contributes significantly to weight reduction, which in turn enhances fuel efficiency and overall performance. By utilizing advanced composite materials, the A350 achieves a lower overall aircraft weight compared to traditional aluminum structures, allowing for improved aerodynamics and greater payload capacity.

CFRP provides excellent strength-to-weight ratios, corrosion resistance, and the ability to be molded into complex shapes, which suits the design requirements of both the fuselage and the wings exceptionally well. This innovative approach is part of Airbus's commitment to building more efficient and eco-friendly airplanes, making the A350 one of the first long-haul aircraft to extensively use composite materials in its structure.

The other sections mentioned do not utilize CFRP entirely. For instance, the tail section may have composite elements, but it is not made entirely of CFRP. The engine nacelles consist of various materials including metal composites, and the landing gear is primarily made from traditional metals for their strength and safety in supporting heavy loads during takeoff and landing.
