摘要： PROBLEM TO BE SOLVED: To provide a method for treating a carbon fiber bundle, by which even a thick carbon fiber bundle such as a large tow can eliminate treatment irregularity at the level of single fibers in a surface-electrolyzing treatment process on the production of the carbon fiber bundle to give the carbon fiber bundle having excellent adhesiveness to matrix resins and excellent composite characteristics.
SOLUTION: This method for treating the carbon fiber bundle is characterized by preliminarily immersing the carbon fiber bundle in an electrolyte solution and then applying a surface electrolysis treatment to the carbon fiber bundle. The electrolyte solution includes an acidic or alkaline aqueous solution.
