Abstract
This article have reviewed the preparation processes, flow path and methods of today's high-performance mesophase asphalt-based carbon fiber, and illustrated the advantages of preparation of high performance asphalt-based carbon fiber. Besides, today's main methods of preparation of asphalt-based carbon fiber have been found, and the key problems of preparation of high performance carbon fiber have been figured out.It is very complex and difficult to control accurately. Preparation of mesophase asphalt-based carbon fiber is mainly reflected in the following points: (1) The selection of asphalt; (2) The quality of the spinning; (3) The effect of oxidation treatment; (4) The temperature during carbonization and graphitization process.
