OBHE is committed to basic research of new materials, new technologies and new equipments, and development of engineering technologies, a whole set of high-performance carbon fiber has been launched successfully which can realize stable production of carbon fiber HT300 and HT700.

It can provide the technology of carbon fiber precursors based on acrylonitrile which production capacity can reach 5,000t/year.

This technology based on one-step production of round fiber from dimethyl sulfoxide which named as green solvent medium.

It is adopted solution polymerization and one-step dry-wet spinning in which DMSO is used as solvent.

The current technical route and key technologies of high-performance carbon fiber which based on PAN have some advancement and renovation.
