DT新材料·2025-09-21 23:07Core Viewpoint - Shanghai Petrochemical, a subsidiary of Sinopec, has launched a new 60K large tow carbon fiber product, filling a gap in the domestic market and achieving international leading performance, with broad application prospects in deep-sea offshore wind power and bridge construction [2][4]. Group 1: Product Development and Performance - The new 60K large tow carbon fiber has a 25% increase in single filament content compared to the 48K variant, with mechanical properties significantly enhanced, including a strength increase of 0.5 GPa and a modulus increase of 20 GPa, enabling a 25% efficiency improvement in production lines [4][6]. - The tensile strength of the 60K carbon fiber bundle exceeds 4.9 GPa, capable of lifting a 1-ton weight, and the elastic modulus can reach over 260 GPa, making it suitable for larger and more powerful deep-sea wind turbine blades [4][6]. Group 2: Technological Advancements - Shanghai Petrochemical has successfully overcome industrial preparation technology challenges for 60K and above large capacity single nozzle production, achieving full-process industrial trial production, marking a domestic first [6][7]. - The company now has production capabilities for nearly 20 different specifications of carbon fiber products, including 3K, 12K, 24K, 48K, and 60K, covering a full spectrum of "general + high performance" and "large tow + small tow" products [6][7]. Group 3: Market Applications and Collaborations - Shanghai Petrochemical is the first in China and the fourth globally to master large tow carbon fiber technology, actively expanding market applications in wind power and other fields [7]. - The company has successfully applied 48K large tow carbon fiber in 131-meter long onshore wind turbine blades, demonstrating its commitment to enhancing the carbon fiber industry chain and supporting "Made in China" initiatives [7][18].
