ABSTRACT:
A method for detecting the surface characteristic of a carbon fiber, which comprises making the carbon fiber travel through an electrolyte solution, applying an electric potential in said solution between the carbon fiber serving as a working electrode and a counter electrode provided in the solution, said potential being varied continuously within a range of potential not higher than the standard electrode potential, and detecting continuously the resulting charnge of intensity of electric current, and a process for producing a carbon fiber giving a high interfacial bond strength between the fiber and matrix resin, which comprises making the carbon fiber have a constant surface characteristic by application of the above-mentioned detection method.
