Abstract : The current programme has focussed on the adhesive bonding ot fibre-composites, based upon thermoplastic polymeric matrices, and the adhesive bonding of aluminium alloys. In both cases a structural epoxy-film adhesive has been employed. The thermoplastic-composite substrates consisted of (i) carbon-fibre/PEEK and (ii) glass-fibre/PPS materials. For all the substrates a range of surface pretreatments has been studied. A fracture mechanics approach has been adopted, and both monotonically-loaded and cyclic-fatigue loaded tests have been undertaken. Also, tests have been conducted in both 'dry' and 'wet' environments. Finally, a model has been proposed which predicts the long-term failure of bonded lap joints from the short-term fracture mechanics data.
