Nowadays the interest of surface preparation in order to manufacture lighter bonded assemblies is well recognized. However only few study dealing with ageing of bonded composite assembly is described in the literature. The present paper mainly aims to compare the influence of the polymer surface thickness of carbon/epoxy composites on the adhesion behaviour at the initial state and after thermo‐oxydative ageing. Conclusions show that contrary to the initial state, the reduction of the polymer surface layer thickness does not improve ageing behaviour. Indeed, the increase of polymer thickness provides a good protection of the degradation coming from micro/macro voids from the adhesive layer.
