This study investigates the mechanisms governing the degradation of co-consolidated titanium-C/PEKK interfaces. Atomic force microscopy was used to demonstrate that the titanium-oxide surface adsorbs moisture. Combined with the diffusion of water molecules through the composite tape material, this causes a severe deterioration of the co-consolidated titanium-C/PEKK interfacial toughness, as measured by means of a mandrel peel test on conditioned specimen. A partial recovery of the interfacial toughness after drying of the specimens indicates that the degradation is reversible, providing evidence that the interaction between titanium and C/PEKK is predominantly characterized by secondary bonds.
