Proportion of Carbon Fiber Usage in the Aviation Industry

     The proportion of carbon fiber usage in the aviation industry varies depending on the type of aircraft. Below are the approximate proportions:

1. 1. Commercial Airliners:

      • In large commercial aircraft, the usage of carbon fiber composites is steadily increasing.
        • Boeing 787 and Airbus A350XWB: Over 50% of the fuselage structure consists of carbon fiber composites.
        • China’s C919: About 12% of the medium-sized jet uses carbon fiber composites.
        • China’s C929 (future model): Expected to reach 51%.

   2. Military Aircraft:

      • Fighter jets and helicopters also show significant and growing use of carbon fiber.
        • F-22 Raptor: 24% of the structure is made of carbon fiber composites.
        • F-35 Lightning II: 36%.
        • China’s J-20: Over 27% of its fuselage components use carbon fiber.
        • OH-1 Ninja Helicopter (Japan): 40% of the fuselage, with rotor blades also made of carbon fiber.

   3. Small Business Jets and Helicopters:

      • The usage of carbon fiber in these aircraft is particularly high, ranging between 70%-80% of their structures
