Recently, Zhang Shouchun, a researcher at the Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences, and the polyacrylonitrile-based ultra-high-strength carbon fiber prepared by the key deployment project of the Chinese Academy of Sciences around the preparation of T-1000-grade ultra-high-strength carbon fiber successfully passed the acceptance and successfully developed a new hollow carbon fiber
based on polyacrylonitrile.
Zhang Shouchun's team adopted the dry spray wet spinning route to carry out the optimization design of the precursor chain structure, the rheology control of spinning fluid, the control of fiber micro-nano structure and the key equipment technology system, and achieved a breakthrough in
the key core technologies of dry spray wet spinning.
The prepared T-1000 grade ultra-high strength carbon fiber has both high tensile strength and high elastic modulus characteristics, and the performance indicators have reached the advanced level
in the industry after testing by third-party institutions.
This research will help the development of multiple varieties and series of high-performance carbon fiber in China, and has positive significance
for structural lightweight and multi-functional applications.
