关键性突破！“地表超强材料”来了

Core Viewpoint - The successful completion and production of a high-performance carbon fiber project in Shanxi marks a significant breakthrough in the domestic mass production of T1000-grade carbon fiber, which is crucial for various high-tech and defense applications in China [1]. Group 1: Project Overview - The high-performance carbon fiber project in Datong City, Shanxi, has achieved the domestic mass production of 12K small tow 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 complete production by November 30, 2025 [1]. Group 2: Product Specifications - 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 [1]. - The density of this carbon fiber is only one-fourth that of steel, while its strength is over five times that of steel [1]. - A one-meter long bundle of this carbon fiber weighs just 0.5 grams but can support over 200 kilograms of load [1]. 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 an exceptional material [1]. - This development breaks China's reliance on imported high-end carbon fiber and has significant applications in national defense, aerospace, rail transportation, and low-altitude economy, playing a vital role in ensuring the security of national strategic materials [1].
