Abstract : Various methods for improving the interlaminar shear strength of graphite fiber-resin matrix composites were developed which basically were found to be controlled surface oxidation phenomena. These include gaseous oxidation, liquid oxidation and solid oxidation. Of the processes studied, gaseous oxidation using oxygen and chlorine, and an electrolytic liquid oxidation porcess using sodium hydroxide as the electrolyte were developed to produce comprehensive physical property data in which all the physical properties of the composite were improved.
