从实验室到生产线：国产高性能碳纤维开启产业新篇章

Core Viewpoint - The production of domestically manufactured T1000-grade carbon fiber in Shanxi, China, marks a significant breakthrough in high-performance materials, previously dominated by foreign entities [1][3]. Group 1: Production Process - The T1000-grade carbon fiber is produced through a sophisticated process involving the polymerization of acrylonitrile into a gel-like solution, followed by extrusion and various processing stages, resulting in a high-quality final product [1]. - The production line, established by the Chinese Academy of Sciences and Huayang Carbon Material Technology Co., has achieved key milestones, with qualified products produced by September 2025 and official production commencing in November 2025 [1]. Group 2: Technical Advancements - T1000-grade carbon fiber boasts a carbon content exceeding 90%, with a strength 5 to 7 times that of steel, making it essential for high-end applications in aerospace and other strategic sectors [3]. - The new carbon fiber exhibits superior properties, including corrosion resistance and stability at extreme temperatures, capable of withstanding up to 1000 degrees Celsius and maintaining performance at -180 degrees Celsius [4]. Group 3: Challenges and Solutions - Transitioning from laboratory success to stable mass production posed significant engineering challenges, particularly in maintaining production stability, as the T1000's strength exceeds that of T800 by 10%-20% [6]. - A critical issue was identified during production stability tests, where a misselected flow control valve caused fluctuations in the production environment, which was resolved by replacing the faulty component [6]. Group 4: Future Prospects - The successful mass production of T1000-grade carbon fiber signifies a shift from "catching up" to "keeping pace" in the industry, with applications anticipated in national defense, aerospace, rail transportation, and renewable energy sectors [7]. - The research team aims to develop even higher strength T1200-grade carbon fiber and expand its industrial applications, enhancing the material's impact across various fields [7].
