Fuselage structural components: Carbon fiber can be used to manufacture the main structure of the fuselage. For instance, the Boeing 787 aircraft extensively uses carbon fiber composite materials in its fuselage, with the proportion reaching up to 50%. This effectively reduces the weight of the fuselage, enhances fuel efficiency, and at the same time strengthens the fuselage’s strength and fatigue resistance.

Wing Component 1: The wing is a key component of an aircraft and has extremely high requirements for the strength and rigidity of the material. The high specific strength and high specific stiffness characteristics of carbon fiber composite materials make them ideal materials for wing manufacturing. They can reduce weight while ensuring that the wings have good aerodynamic performance and structural stability. For instance, the wings of the Airbus A350 extensively use carbon fiber materials.

Tail wing assembly: It includes horizontal tail wings and vertical tail wings, etc. The early Boeing 737 aircraft’s spoilers and horizontal stabilizers had already adopted carbon fiber composite materials. Nowadays, more aircraft tail fins are made entirely or partially of carbon fiber, which can effectively enhance the handling performance and stability of the tail fins while reducing their weight.

Engine-related components 2: Carbon fiber composite materials are often used to manufacture engine fan blades, casings and other components. For instance, the casing of the GE9X engine is made of carbon fiber composite material, which reduces the weight by nearly 160 kilograms compared to metal materials. The Rolls-Royce Advance engine features carbon fiber composite blades and casings. Compared with the earlier Trent engines, it can reduce the weight by 680 kilograms and improve fuel efficiency by 20%. In addition, high-temperature components such as the variable relief valve guide of the GEnx engine and the mixed-flow nozzle of the Russian SaM146 engine also adopt carbon fiber reinforced composite materials, which not only reduce the weight but also have excellent high-temperature resistance.

Interior components: Carbon fiber materials are also used in aircraft interiors such as seats, luggage racks, and decorative panels. Carbon fiber seats are light in weight and high in strength, providing passengers with a comfortable riding experience while reducing the overall weight of the aircraft. Carbon fiber luggage racks and decorative panels can enhance the overall texture and grade of the cabin with their attractive appearance and excellent performance.

Drone fuselage 3: For instance, the world’s largest cargo drone, the Beluga Route W5000, after its fuselage was made of carbon fiber composite materials, its weight was effectively reduced by 40%, its maximum cargo capacity was increased to 5 tons, and its range exceeded 2,600 kilometers, achieving lightweight, high load capacity and long endurance.
