Adhesive bonding of stainless steel : strength and durability
type: CreativeWork
description: Adhesive bonding as an alternative method of joining materials together has many advantages over the more conventional joining methods such as fusion and spot welding, bolting and riveting. For example, adhesives can be used to bond dissimilar materials, adhesive joints have a high stiffness to weight ratio and the stress distribution within the joint is much improved. Stainless steels are commonly used in applications that would clearly benefit from adhesive bonding; architectural cladding, because of the large bond areas involved, and in the railway industry, due to improved acoustic insulation and greater fatigue resistance. The work presented in this thesis is concerned with adhesive bonding of stainless steels intended for structural applications. As a starting point to the investigation, a review of the literature was conducted, covering the intrinsic mechanisms of adhesion, the significance of the chemical and physical nature of the adherend surface, the types of structural adhesives, the methods of testing adhesive joints and surface characterisation techniques. The first experimental stage, involved a screening programme to evaluate a number of candidate adhesive systems and adherend surface pre-treatments. Standard single overlap shear and floating roller peel tests conducted in ambient conditions were employed in the discrimination and the degree of compatibility between adhesive and adherend, as measured by the proportion of cohesive failure on the post-fracture face, was also considered. In the second stage of the experimental work, lap shear tests were used to evaluate the affects of surface contamination on joint strength. In addition, lap shear and peel tests were considered to assess the significance of the adhesive bondline and primer thickness. In order to assess the environmental durability of adhesive joints, lap shear and peel tests were conducted after ageing in ambient and high humidity environments. To compliment the data, Boeing wedge crack…
