Weight-critical marine structures, such as high-speed craft, are often made of high-strength aluminium. To improve the performance of such structures, there is a tendency to seeking lighter weight materials, especially in parts of the structure where weight-saving is particularly beneficial, such as in the superstructure. Such leight-weight materials can be fibre-reinforced composites. When joining structures made of composites to components of steel or aluminium, welding, which is the traditional joining method in marine applications, is no longer an option. Instead, adhesive bonding becomes an attractive joining method. In the present work the strength of different bonded double-lap steel-composite joints, with a variety of overlap lengths and environmental conditions, has been measured experimentally. These experimental results have been compared with predictions using an elastic-plastic theory recently derived by the present authors, as well as linear models. It is demonstrated that predictions using the new nonlinear theory agree well with the experimentally obtained results, while linear analysis is inappropriate for modeling such joints when loaded to failure.
