Abstract

Increasing interest is being shown in the use of adhesive bonding as an alternative, or complementary assembly technique to spot welding for the fabrication of sheet metal structures in the automotive, household appliance and building industries. The current research work programme was aimed at developing an understanding of the mechanisms controlling durability of the adhesive bond, and the changes which occur both within the adhesive itself and at the adhesive/steel interface during exposure to a range of both accelerated and natural environments. Determination of the important surface characteristics, both physical and chemical, which contribute to bond development and stability for uncoated mild steel, zinc/zinc alloy and organic coated steels were also examined. Since the selection of adhesive can also have a significant effect on durability, the effect of adhesive type relative to the substrates selected was also investigated. In addition, the potential of various pretreatments in enhancing the durability of adhesive bonded joints in uncoated/metallic coated steels were studied. Finally, the static and dynamic properties (ie torsion/impact performance of bonded structures before and after exposure to a hostile environment) were examined.
