Many fiber-reinforced composite structures are made up of a number of modules for ease of manufacturing and handling. Modular construction requires some form of joining system that will transmit the applied loading between the different modules and give adequate performance over the service life of the component. This paper reviews the different analytical approaches used to study bonded joints and presents a simple analysis to predict failure loads for a specific type of bonded joints, namely the lap joint. The present analysis is compared with two more rigorous analyses and found to give good results. Experiments were also carried out on glass fiber specimens and it is concluded that the present approach compares well with test results.
