Abstract

Adhesively bonded joints are increasingly being used in aerospace and automotive industries. The use of adhesive bonding rather than mechanical fasteners offers the potential for reduced weight and cost. Since the joint strength is influenced by many factors such as the type of adhesive, the type of adherent, the overlap length, roughness of adherent surface and the bond line thickness, therefore, there is scope to improve the joint strength. The main objective of this work is to study the influence of the macroscopic state of the adherent surface on the strength of adhesive joints. To study the same, different types of texture are drawn on the adherent surface in CAD software. In addition to the surface texture the influence of the thickness of adhesive on the strength of single lap joints has been studied using FEA software for several adhesives. To analyse the effect of each parameter on the strength of adhesive joint a Taguchi method is applied. All the models of single lap joints will be drawn using CAD software and analysis is done in Ansys 16.0. The results coming out from numerical analysis are compared with the computerized UTM test taken under static loading.
