The objective of the proposed RTD is to develop innovative non thermal joining methods for the production of lightweight aluminum marine structures. Initial research indicates that production time of marine structures can be reduced significantly (20 30%) when non thermal joining techniques are made available for the efficient and reliable production of marine structures as welding distortions can be eliminated. In addition substantial weight savings (10 15%) can be realized as thinner materials can be considered for the construction of primary and secondary structural components. Further weight savings in highspeed marine structures will benefit the total operational economy as great reductions in fuel consumption and payload increases result. Improvements in production economy, operation eConOmv and environmental benefits due to the protection of resources form the principal impact of the intended RTD. The RTD programme will focus on the application of selected non thermal joining techniques. Structural panels will be built and tested. The technology will be expanded to larger scantlings. A comprehensive test programme involving static and dynamic tests and simultaneous FEM-Analysis will form the basis of the quantification of load bearing capacities and fatigue performance of the investigated panels. A classification of non thermal joining methods and tools versus the hierarchy of structural components of highspeed marine structures will form the principal result of the RTD.
