STUDIES OF ANODIC OXIDATIVE SURFACE TREATMENT OF GRAPHITE FIBERS

Anodic oxidative surface treatment of graphite fibers in four anolytes of ammonium was studied.Mechanical properties including tensile strength and modulus of anodic treated monofilament were determined and surficial morphology and chemical composition were characterized by SEM and XPS.The adhesion between graphite fibers and epoxy matrix was evaluated in terms of interlaminar shear strength(ILSS).
