Recently, the adhesive bonding technique has become an important problem as FRP is now being applied to large structural constructions. In the past, the studies of structural adhesive bonding were usually made on the adhesive lap joints of aluminum adherents, and the fracture behaviors of these adhesive joints were simply followed by identifying the fracture type as the cohesion fracture of adhesive layers or the interfacial fracture. However, FRP lap joints usually show very complicated fracture. So, in this report, it was attempted to investigate the fracture behaviors and the configuration of the FRP adhesive lap joints. The correlation between deformation and fracture of the lap joints was examined based on the experimental results. The results showed that the deformation of the lap joint was directly related to the joint shapes (lap length and scarf angle). Furthermore, the fracture behaviors of FRP adhesive joints were discussed and clarified.
