SAFEJOINT “Enhancing structural efficiency through novel dissimilar material joining techniques?
Development of new technologies for the design and manufacture of metal-to-metal and metal-to-composite joints that allow for the generation of solutions lightened structural structures combining different materials. Improvement of conventional adhesive bonding and soldering techniques by means of the incorporation of new materials and surface treatments, and to through optimized processes and designs.
As an example of the current activity in this field, the ITA is currently participating in the European project SAFEJOINT ? Enhancing structural efficiency through novel dissimilar material joining techniques?, financed by the European Commission, and in which it leads some of the main lines of work of the project.
ITA’s work is providing a much better understanding of how they work. adhesives and how joints should be designed to achieve the best results. better results from a functional point of view. This will allow This technique can be used in more and more demanding applications.
As a bonding technology, adhesives are becoming more and more widely used for used in many sectors such as the automotive, railway and aeronautics. Other sectors in which they are also used in the form of is notorious is in the construction and manufacture of windmill blades wind farms. This is because the adhesives provide a number of advantages. advantages that, in many cases, clearly position them as the best option when resolving a joint: they are characterized by the following characteristics high resistance to corrosion or degradation even in harsh environments. aggressive, they allow to obtain continuous and “unseen” bond lines. from the outside, they provide the possibility of achieving watertight connections and, by means of a correct selection of materials, they make it possible to achieve high energy and vibration absorption capacities.
Finally, there is a multitude of application examples where the evidence that the lightest solutions often result from the combination of different materials, through the integration of and using them in such a way as to make the best possible use of their properties. From this point of view, given that adhesives are The use of these technologies makes it possible to join dissimilar materials (plastics, metals, etc.), composites, etc.) where welding cannot be used, it is one of the most important techniques that offer the greatest potential for weight savings.
