Abstract:

The treatment of carbon fiber surfaces by oxidation, vapor deposition, and solution- reduction is described. The surfaces of treated and untreated fibers are characterized by various techniques. The solution-reduction treatments were the most effective, producing carbonepoxy composite shear strengths up to 12,000 psi. The method is extremely fast, requiring less than one minute of residence time. This approach has commercial significance when compared with currently used oxidation treatments requiring several hours. P.S.-PL
