en.Wedoany.com Reported - China TISCO Group's Steel Science Company recently successfully completed the engineering trial of T1100S-grade ultra-high strength carbon fiber in a single run on its existing 500-ton annual carbon fiber production line. The tensile strength of the product has consistently reached over 7.0 GPa, with all key performance indicators being excellent, achieving a domestic leading and internationally advanced level.
High-performance carbon fiber is a key strategic material supporting aerospace, high-end equipment manufacturing, and other sectors. T1100S-grade carbon fiber belongs to the industry's top-tier high-modulus, ultra-high strength product series, characterized by high technical barriers and stringent process control precision, and has long been a key focus of domestic new material research. As a mainstay in the domestic localization of carbon fiber, Steel Science Company, while achieving stable mass production of T300, T700, T800, and T1000-grade series products, continues to focus on the iterative upgrade of high-end products.
To overcome the core preparation technology for T1100S, Steel Science Company established a dedicated technical research team, delving deep into the optimization of the entire process chain including precursor polymerization, dry-jet wet spinning, pre-oxidation, and high-temperature carbonization. It continuously tackled industry challenges such as uneven precursor microstructure, carbonization defect control, and performance stability fluctuations. By scientifically coordinating production and R&D schedules, Steel Science Company fully utilized gaps in routine production supply to conduct trial production of high-end new products during off-peak times, maximizing the utilization of existing production line resources, ultimately achieving a successful single-batch trial production on the first attempt.
TISCO Group is a core enterprise under China's Baowu Steel Group Co., Ltd., headquartered in Taiyuan City, Shanxi Province, and is one of the world's largest stainless steel producers. Steel Science Company is a subsidiary of TISCO Group, specializing in the R&D and production of carbon fiber materials. The success of this T1100S-grade carbon fiber engineering trial fully validates the flexible manufacturing capability of Steel Science Company's 500-ton annual carbon fiber production line, as well as the stability and advancement of its localized processes. In the next phase, Steel Science Company will continue to advance the process solidification and stable mass production of T1100S-grade carbon fiber, persistently expanding its application scenarios in high-end fields.
