Abstract

The tensile and fatigue experiments were conducted with tensile-peel specimens for investigating on strength of adhesively bonded and mechanical press joints of aluminum sheet used in the field of the automobile industry. The combining epoxy adhesive bonding and mechanical press joining exhibits an increase in joining force as a result of interaction between static forces of the two joining methods. The fatigue strength of pure adhesive joint was measured as 91% of that of the combination of adhesive bond and mechanical press joint, suggesting that the interaction between the bonding and mechanical joining was about 9%.
