Abstract
A research study on the fatigue performance of hybrid adhesive joints was carried out to investigate the fatigue performance of adhesive joint and hybrid adhesive joint using dissimilar material. A 3 mm thin plate of aluminium A7075 and stainless steel 304 are used as the adherend material for experimental test and the adhesive used was high performance Araldite epoxy adhesive. Maximum fatigue life was achieved for the hybrid adhesive joint with an optimum overlap length of 59 mm and the adhesive thickness of 0.2 mm. The fatigue damaged occurs on the adherend surface for adhesive joint and adherend crack for hybrid adhesive joint. Results showed an increment of fatigue life with shear stress reduction.
