As China’s low-altitude economy transitions from pilot flights to commercial operations in 2026, electric Vertical Takeoff and Landing (eVTOL) aircraft have entered a critical commercialization phase — and carbon fiber composites have become an indispensable material, driven by their unparalleled lightweighting advantages.

Industry estimates indicate that a single eVTOL requires 100 to 400 kilograms of carbon fiber, with composites typically accounting for over 70% of the airframe structure, and in some models as much as 85%. Lightweighting directly determines range and payload capacity — the industry consensus holds that every kilogram saved adds approximately 3 kilometers of flight range.

With domestic T1200-grade ultra-high-strength carbon fiber now in mass production, this performance leap is reshaping eVTOL design boundaries. Compared to T1100-grade fiber, T1200 delivers a 14% higher tensile strength, meaning engineers can achieve equivalent structural rigidity with thinner wall thickness. Every gram saved translates directly into additional battery capacity or passenger payload — a critical factor in commercial operational economics.

Carbon Fiber Applications Across Leading eVTOL Models:

  AutoFlight “Prosperity”: T1100-grade carbon fiber + epoxy resin composite fuselage reduces airframe weight from 350kg to 245kg — a 30% weight cut that extends range from 120km to 150km (+25%).

  EHang EH216-S: Upgraded T1100-grade carbon fiber arms deliver 40% higher fatigue strength and significantly extended service life.

AE200: Over 85% composite content by weight, achieving more than 40% weight reduction versus traditional metal structures, with 2,000+ test flights completed.

CCID Research forecasts that China’s low-altitude economy will surpass 1.2 trillion yuan in scale by 2026. As eVTOLs move from prototype validation to volume delivery, carbon fiber demand is set for large-scale growth, becoming the next major growth driver alongside wind energy and hydrogen storage.
