Globalization and the ability to travel all over the world within no time by aircraft were the decisive reasons why the Corona virus was able to spread so quick everywhere. Due to this risk air traffic decreased 2020 by 75% (in Germany). The DLR-projects germfree flying and FIONA are focused on the development of germ-free cabin surfaces to avoid disease via contact transmission. Anti-microbial materials such as zinc, copper, silver as well as carbon and chitosan are integrated into the lay-up of composites. The metals donate ions and therefore have germ-killing effects. Carbon and chitosan also feature anti-microbial properties but the driving mechanisms are still under research. However, all materials are available as powers, which can be either be incorporated into epoxy resins as part of a laminate, or in thermoplastics to be 3D printed. Alternatively, nano-scopic films of these materials can be coated on the surfaces to reduce mass, costs and improve efficiency. Additionally, electrothermal heating systems are also integrated to neutralize biofilms actively. To test the anti-microbial effect intensive contact killing tests are carried out. The aim is to find a highly effective, cheap, lightweight and durable material combination which can easily be applied on surfaces as a retrofit to reduce the risk of contact infection within an aircraft cabin.
