Dissimilar material joining is widely used for many applications such as automobiles, electric devices, and so on. Adhesive strength is one of the most important factors in joining. There are various theories for adhesion of dissimilar materials such as anchor effect, molecular interaction and chemical bonding, however, adhesive mechanism is difficult to understand, because some theories working at same time, and make complex interaction each other.
In this study, the influence of interface property (effect of micro groove) on adhesive strength of SUS 304 / epoxy resin bonded body was investigated. Higher adhesive strength was indicated on specimen with higher angle interface grooves to the shear loading direction. Delamination crack path analysis was also carried out in this study. The crack path was strongly dependent on the angle of the interface grooves, and specimen that, indicated higher adhesive strength shown crack propagation near the interface.
