关键性突破！“地表超强材料”来了

Core Viewpoint - The successful production of domestically manufactured T1000-grade high-performance carbon fiber in Shanxi marks a significant breakthrough in the large-scale production of high-performance carbon fiber in China, which is crucial for various strategic industries [1][5]. Group 1: Project Overview - The high-performance carbon fiber project in Datong, Shanxi, has completed its construction and is now in production, achieving a key milestone in the domestic production of T1000-grade carbon fiber [1]. - The first phase of the project includes a demonstration production line with a capacity of 200 tons per year, set to commence full construction in June 2024 and expected to be operational by November 30, 2025 [5]. Group 2: Product Characteristics - The T1000-grade carbon fiber produced has a single filament diameter of only 6 to 7 micrometers, which is less than one-tenth the thickness of a human hair, yet it boasts a tensile strength exceeding 6400 MPa [5]. - This carbon fiber has a density that is only one-fourth that of steel, while its strength is over five times greater than that of steel, demonstrating its exceptional lightweight and high-strength properties [5]. - A one-meter long bundle of this carbon fiber weighs only 0.5 grams but can support a load of over 200 kilograms, showcasing its remarkable load-bearing capacity [5]. Group 3: Applications and Significance - The T1000-grade carbon fiber integrates core advantages such as high strength, lightweight, high and low-temperature resistance, corrosion resistance, wear resistance, and good thermal and electrical conductivity, making it a "super material" [5]. - The production of this carbon fiber is expected to reduce China's reliance on imported high-end carbon fibers and has significant implications for national defense, aerospace, rail transportation, and low-altitude economy sectors, thereby ensuring the security of strategic materials [3][5].
