科学与健康|从“无米下炊”到“高端迭代”：我国高性能碳纤维的创新跨越

Core Viewpoint - The successful production of T1000-grade high-performance carbon fiber in Shanxi represents a significant advancement in China's material industry, marking a transition from reliance on foreign technology to self-sufficiency and innovation in high-end materials [2][5]. Group 1: Technological Development - The development of carbon fiber in China began in the 1970s, with significant advancements made over the decades, including the production of T700 and T800 grades, leading to a rapid increase in domestic demand and production [3]. - The research team aimed to tackle higher technical challenges starting in 2016, focusing on the development of dry-spinning wet-method carbon fiber technology, which involved extensive research and collaboration over eight years [3]. - The T1000-grade carbon fiber has a single filament diameter less than one-tenth that of a human hair, with a tensile strength exceeding 6600 MPa, capable of lifting approximately 200 kilograms [3]. Group 2: Industrial Impact - The first phase of the thousand-ton high-performance carbon fiber project was completed in just one and a half years, showcasing effective collaboration between researchers and engineers to align laboratory results with industrial needs [5]. - The successful production of T1000-grade carbon fiber signifies a crucial leap for China from "catching up" to "keeping pace" in the high-performance carbon fiber sector, filling a gap in domestic high-end production capacity [5]. - This innovation provides a foundational material for critical sectors such as aerospace, new energy, and low-altitude economy, reinforcing China's commitment to maintaining control over key technological developments [5].
