ABSTRACT:
The surface of a carbon fiber is treated to improve the strength of its bond with a matrix. The fiber is made an anode by connecting it electrically with the anode current input terminal of an electrolytic treatment bath containing an electrolyte and having a cathode. The fiber is subjected to electrolysis in the bath. The relative distance between the fiber and the cathode in the bath decreases as the distance from the anode current input terminal along the fiber is increased.
