POLY-ACRYLONITRILE BASED POLYMER SOLUTION, MANUFACTURING METHOD THEREOF, CARBON FIBER PRECURSOR FIBER, CARBON FIBER PRECURSOR FIBER MANUFACTURING METHOD, AND CARBON FIBER MANUFACTURING METHOD

摘要

Disclosed is a method for manufacturing carbon fiber which comprises the use of un-reacted raw material monomers in solution to prepare the precursor fiber for making the carbon fiber, and a relatively short passage period through hydrogen, which reduce production costs and increase returns. The present invention further comprises the carbon fiber precursors made thereby.
