Interfacial interactions developing in polycarbonate/carbon fiber composites were modified by the surface treatment of the anodically oxidized fibers. The treatment with coupling agents containing epoxy, anhydride and izocianate reactive groups led to the increase of interfacial adhesion in most cases. The reactive groups on the surface of the treated fiber react with the chain-end hydroxyl groups of polycarbonate. The number of active-OH groups is mall compared to the reactive groups of the treated fiber, thus the maximum value of interfacial shear stress was practically independent of the chemical structure of the coupling agent. The compound with the anhydride functional group formed a strong and rigid film on the fiber surface, which did not react with the polycarbonate matrix even at the high temperature of processing.
