培育新质生产力在行动｜“新材料之王”从实验室迈上生产线

Core Viewpoint - The production of T1000-grade carbon fiber in Shanxi, China, marks a significant breakthrough in high-performance materials, previously dominated by foreign countries, enabling advancements in various strategic sectors [1][2]. Group 1: Production and Technology - The T1000-grade carbon fiber, known for its strength exceeding that of steel by 5 to 7 times, is produced using a unique process that includes a proprietary raw material formula and dry-wet spinning technology, addressing the issue of brittleness [2][3]. - The production line, established by the Shanxi Coal Chemical Research Institute and Shanxi Huayang Carbon Material Technology Co., has achieved stable mass production, transitioning from laboratory success to industrial-scale output [1][4]. Group 2: Performance Characteristics - The newly developed T1000-grade carbon fiber exhibits exceptional properties, including corrosion resistance and stability at extreme temperatures, capable of withstanding up to 1000 degrees Celsius and maintaining performance at -180 degrees Celsius [3]. - In tensile strength tests, the carbon fiber can endure approximately 200 kilograms of force per meter, equivalent to the weight of three adult males, showcasing its superior strength [2]. Group 3: Challenges and Solutions - The transition from pilot production to stable mass production posed significant engineering challenges, particularly in maintaining production stability, as even minor fluctuations could lead to product defects [4][5]. - A critical issue was identified during the production process related to a poorly selected flow control valve, which was resolved, leading to improved stability in production [4]. Group 4: Future Prospects - The successful mass production of T1000-grade carbon fiber signifies a shift from "catching up" to "keeping pace" in the high-performance materials sector, with applications anticipated in defense, aerospace, rail transportation, and renewable energy [5]. - The research team aims to develop even higher strength T1200-grade carbon fiber and expand its industrial applications, further enhancing the material's impact in various fields [5].
