Progress In Dry Spinning Wet Spinning Of Carbon Fibers In China

Shanxi Coal Chemistry Research Institute announced that Zhang Shouchun, a researcher of the Shanxi Coal Chemistry Research Institute of the Chinese Academy of Sciences, was responsible for the preparation of the T1000 super high strength carbon fiber, and assumed the key deployment project of the Chinese Academy of Sciences, and was recently accepted by experts from the Chinese Academy of Sciences.

Polyacrylonitrile based carbon fiber is an indispensable key material in the industrial field.

Polyacrylonitrile carbon fiber production technology mainly has two technical routes: wet spinning and dry jet wet spinning. Dry jet wet spinning technology has the advantages of high production efficiency, good carbon fiber quality and low production cost. At present, the world's high-end brand carbon fiber is mainly produced by dry spray wet spinning technology.

The technology used dry spray wet spinning route, carried out the optimization design of precursor chain structure, rheological control of spinning fluid, fiber micro nano structure control and key equipment technology system, and achieved a breakthrough in the key technology of dry jet wet spinning.

The T1000 grade super high strength carbon fiber has the characteristics of high tensile strength and high elastic modulus. After testing by the third party mechanism, the performance indexes reach the advanced level in the industry.
