Abstract

This work presents a parametric study of adhesively bonded scarf joints enriched with mechanical fasteners. Tensile tests of two different fastener positions along the load path were carried out and compared with bonded scarf joint. It was found that the hybridised joints could carry significant load post adhesive failure with minimal influence on the stiffness of the structure. On further investigation of fastener position in hybrid joints it was found that when fasteners were placed close to each other (equidistant from the centre), could carry a higher load than the joint with fastener placed near the joint edge. The failure modes for the bonded joints was a partial cohesive failure (special cohesive failure) whereas the failure mode of hybrid joints was a substrate failure (shear out) influenced by the fasteners along the load path and partial cohesive failure on the bonded surface.
