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 \u2014 and carbon fiber composites have become an indispensable material, driven by their unparalleled lightweighting advantages.<\/p>\n
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 \u2014 the industry consensus holds that every kilogram saved adds approximately 3 kilometers of flight range.<\/p>\n
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 \u2014 a critical factor in commercial operational economics.<\/p>\n
Carbon Fiber Applications Across Leading eVTOL Models:<\/strong><\/p>\n \u00a0\u00a0<\/strong>AutoFlight “Prosperity”<\/strong>: T1100-grade carbon fiber + epoxy resin composite fuselage reduces airframe weight from 350kg to 245kg \u2014 a 30% weight cut that extends range from 120km to 150km (+25%).<\/p>\n \u00a0\u00a0<\/strong>EHang EH216-S<\/strong>: Upgraded T1100-grade carbon fiber arms deliver 40% higher fatigue strength and significantly extended service life.<\/p>\n AE200<\/strong>: Over 85% composite content by weight, achieving more than 40% weight reduction versus traditional metal structures, with 2,000+ test flights completed.<\/p>\n 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\u00a0driver alongside wind energy and hydrogen storage.<\/p>","protected":false},"excerpt":{"rendered":" Alors que le secteur chinois des vols \u00e0 basse altitude passe des vols d\u2019essai \u00e0 l\u2019exploitation commerciale en 2026, les a\u00e9ronefs \u00e9lectriques \u00e0 d\u00e9collage et atterrissage verticaux (eVTOL) sont entr\u00e9s dans une phase cruciale de commercialisation \u2014 et les composites en fibre de carbone sont devenus un mat\u00e9riau indispensable, gr\u00e2ce \u00e0 leurs avantages in\u00e9gal\u00e9s en mati\u00e8re de l\u00e9g\u00e8ret\u00e9.
