Abstract

The aim of this study was to investigate the effect of fillers content on mechanical strength and failure mode of aluminium bonded with epoxy-based adhesive. Fillers used are iron ore, aluminium powder and silica with mean diameter of 100 µm. The mechanical strength and failure mode of the adhesive joints was determined by utilizing T-peel and single lap-shear tests and by using macro photo and scanning electron microscope, respectively. The effect of three different ?llers on mechanical strength of adhesive was investigated with choosing the highest peel strength and shear strength. The highest value in peel and shear tests were attained with silica and aluminium powder, respectively. The joints fail in mixed failure mode (cohesive and adhesive mode). This is shown that the joint strength depended on the adhesive properties and the bond adhesion between the adhesive and adherent.
