This article summarized worldwide history of PAN-based carbon fiber development, analyzed and discussed developing process of the carbon fiber in the past four decades in China. With the breaking key technologies in AN/DMSO solution polymerization and in wet-spinning of carbon fiber precursor preparation, development strategies of high performance carbon fiber in China has been determined. The transformation and updating of the high performance carbon fiber production in China has been achieved due to the breakthrough of PAN-based carbon fiber technology using organic solvents system. The progress has not only provided powerful technology platforms for rapid development of the carbon fiber in the last decades, but also supported sustainable development of the high performance carbon fiber products and technologies. Based on above development, a technology system in which DMSO system is taken as technology majority has been established. This article also described the localization of carbon fiber products and related technologies as well as current status were introduced in detail, challenges and obstacles that are still standing on the way of carbon fiber localization were also analyzed, with suggestions were proposed.
