© 2016 Walter de Gruyter GmbH, Berlin/Boston. Joining ofmaterials in structuraldesign has alwaysbeen a challenge for engineers.Boltingand riveting has been used formany years, until the emergence of fusion welding which revolutionised construction in areas such as shipbuilding, automotive, infrastructure and consumer goods. Extensive research in the past 50years has resulted in better understanding of the process andminimised the occurrence of failures associated with fusion welding such as, residual stress cracking, stress corrosion and corrosion fatigue cracking, localised reduction in mechanical properties due to microstructural changes (heat affected zone) etc. Bonding has been a technique that has been proposed as an alternative because it eliminates several of the problems associated with fusion welding. But, despite some applications it has not seen wide use. There is however a renewed interest in adhesively bonded joints, as designers look for ever more efficient structureswhich inevitably leads to the use and consequently joining of combinations of lightweight materials, oftenwith fundamentally different mechanical and physical properties. This chapter provides a reviewof adhesively bonded joints and reports on improvements to bonded joint strength through the introduction of carbon nanotubes at the bond interface. Results from various workers in the field are reported aswell as the findings of the authors in this area of research. It is obvious that there are several challenges that need to be addressed to further enhance the strength of bonded joints and worldwide research is currently underway to address those shortcomings and build confidence in the implementation of these new techniques
