Optimal Selection for Dissimilar Materials using Adhesive Bonding and Mechanical Joining

© Published under licence by IOP Publishing Ltd. In the present study, an investigation of double lap joints using two different joining methods was carried out. Carbon fiber and glass fiber reinforced materials were the composite materials that joined with the conventional steel and aluminium. Adhesive bonding joint and a combination of adhesive and mechanical fastener joints were used as a joining approach. It is found that adhesive bonding joint provided a better performance compared to the hybrid joint, where the holes created in the specimens for inserting mechanical fasteners caused a lower strength. It is observed that the adhesive joining of the glass fiber and steel obtained a maximum load of 35.5 KN, which is the highest strength among all other combinations examined in this study, while the similar combination joined using adhesive bonding and mechanical fastener showed a maximum load less than the adhesive joining by 21.4 %.
