Record-Breaking 131-meter Carbon Fiber Onshore Wind Turbine Blade Successfully Launched
On January 21st, Sany Heavy Energy's 131-meter onshore wind turbine blade, fabricated at the Bayan Nur Zero Carbon Digital Industrial Park, was successfully commissioned. This blade, which employs dry-jet wet-spinning 48K large tow high-performance Carbon Fiber (CF) provided by ZF Godeagle, not only breaks the record for the world's longest onshore wind turbine blade but also indicates a significant advancement for domestic dry-jet wet-spinning 48K large tow CF in the supply of blades over 100 meters.
ZF Godeagle's dry-jet wet-spinning 48K large tow high-performance CF, launched in 2023, is the first large tow product globally to utilize the dry-jet wet-spinning technology. This material is characterized by minimal fuzz during pultrusion, good processability, and ease of maintenance. Integrated with ZF Carbon Core's proprietary resin impregnation system and preforming system, it confers exceptional mechanical properties to the CF pultruded plates, including higher modulus, strength, strain, and improved fatigue resistance. These characteristics are vital for ensuring the long-term stable operation of wind turbine blades, providing robust support for the world's longest onshore wind turbine blade.
The wind power industry, trending towards larger-scale models, has entered a "high-speed era" of model iteration. The industry is experiencing structural high growth as it continues to recover. Supporting longer blades inevitably requires the incorporation of CF materials, indicating a broadening horizon for CF applications in wind energy. The rapid expansion of domestic CF production capacity, coupled with multiple large-scale wind power projects, effectively absorbs this capacity and stimulates the economic development of the CF industry, offering stable support for the domestic CF cause.
