The project is devoted to the development of novel active corrosion protection systems for multi-material combinations used in the aircraft design. The development of such new approaches is only possible via deep mechanistic investigation of the degradation processes in confined environments formed at multi-material joints. The second essential objective is finding the synergistic inhibiting combinations which can provide effective suppression of corrosion processes in the case of galvanically coupled dissimilar materials. The ultimate goal is the introduction of inhibiting compounds to the protective layers, adhesives and sealants used in multi-material design of aircrafts. PROAIR is an “industry-academia partnerships and pathways” FP7 project aiming at the creation of stimulating and interdisciplinary R&D and training partnership among actors from the academia and private sector, promoting the exchange of ideas, methods, techniques as well as enabling an accelerated technology transfer from science to industrial scale and of course a continuous collaborations between the stakeholders. The topic demands strongly innovation and interdisciplinary skills, since there is a lot of pressure from the private sector to develop more sustainable solutions for light-weight design of green aircrafts. The developed protection solutions must be compliant with environmental regulations, must present reduced thickness/weight, and must promote energy savings, with longer lifetime. Moreover it has to be considered that the related processing and assembly steps have to be economically competitive.
