TL;DR: Carbon fibers are surface oxidized by contacting the fiber with an aqueous solution comprising 5 - 20 weight percent sodium dichromate and 15 - 45 percent sulfuric acid for from one to sixty minutes at about the boiling point of the mixture as discussed by the authors.
Abstract: Carbon fibers are surface oxidized by contacting the fiber with an aqueous solution comprising 5 - 20 weight percent sodium dichromate and 15 - 45 percent sulfuric acid for from one to sixty minutes at about the boiling point of the mixture. These fibers are useful in making resin-based composites by improving the adhesion between the fibers and the resin.
