It is estimated that the technique of bonding CFRP plates to concrete beams and slabs can save 135 million, over other methods, if used for the strengthening of 2000 concrete bridges in the UK to meet European directive requirement in 1999. However, previous research has shown that plated concrete beams can suffer a form of failure involving peeling-off of the cover concrete in the region of plate curtailment. Although it is recognised that the problem may be eliminated by the provision of external anchorage to the ends of the plates, the detailed peeling failure mechanism is itself not well understood, and the means by which the anchorage methods prevent peeling requires further investigation. This lack of understanding of the essential aspects of peeling threatens to obliterate the cost-effectiveness of the plate-bonding technique. The research proposed here seeks to perform experiments and analyses to investigate the peeling phenomenon, with the ultimate aim of equipping designers with methods of recognising when peeling is imminent, and with means of economically guarding against peeling. This would increase the UK's competitiveness in the composite plate-bonding field, as the technique has considerable potential applications to the rehabilitation of bridges and buildings throughout Europe.
