Abstract
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.
