Core Viewpoint - A significant breakthrough has been achieved in the field of high-performance large tow carbon fiber by a research team led by Wuhan University of Technology, establishing a self-controlled technology system and application ecosystem for the high-quality development of strategic new materials in China [2][3]. Group 1: Industry Development - The carbon fiber industry in China has primarily focused on small tows (1,000 to 12,000 filaments), which are costly and limit large-scale applications. In contrast, large tow carbon fibers (over 48,000 filaments) offer better cost-performance ratios and are becoming the mainstream trend in global demand [3]. - The global demand for large tow carbon fiber has surpassed that of small tows, indicating a shift towards more cost-effective and scalable applications [3]. Group 2: Technological Advancements - Wuhan University of Technology has successfully developed a dry-jet wet spinning preparation technology and complete equipment for stable mass production of 48K high-performance (T700 grade) large tow carbon fiber, achieving a significant increase in tensile strength and a cost reduction of approximately 20% [3]. - The previously restricted complete equipment for large tow carbon fiber production is now fully self-controlled, marking a significant advancement in domestic capabilities [3]. Group 3: Application and Future Prospects - The research team has also addressed the performance degradation of large tow carbon fiber composites during the molding process by developing a low-viscosity, high-wettability resin system, which can be tailored for various applications, including high-temperature and corrosion-resistant functionalities [6]. - This technology has been applied to five representative products, including aerospace rocket engine casings, unmanned drone compartments, unmanned boat hulls, freight vehicle tops in rail transport, and high-end machine tool carbon fiber drive shafts, all of which have passed key performance validations and are ready for mass production [6]. - Future efforts will focus on advancing the application of large tow carbon fiber in critical fields such as aerospace and enhancing downstream support to create an industrial cluster effect [6].
