The ECO-COMPASS project is developing ecological improved composite materials for aircraft interior and secondary structures in a cooperation of Chinese and European partners.
Nowadays, composites are important materials used in aircrafts due to their excellent mechanical performance combined with relatively low weight to enable the reduction of fuel consumption. Carbon fibre reinforced plastics are used in fuselage and wing structures and increasingly replace classic metals. Glass fibre reinforced plastics are mainly used for the interior panels. All these composite materials applied in aviation have one thing in common: they are man-made. Renewable materials like bio-fibres and bio-resins are under investigation for a long time but they have not made it into modern aircraft in noticeable amounts yet.
ECO-COMPASS brings together Chinese and European partners to develop these organic materials.
During the project bio-based and recycled materials will be assessed for their application in aviation. To fulfil the safety requirements and to withstand the special stress in aviation environment, protection technologies to mitigate risks like fire, lightning and moisture uptake will be investigated. An adapted modelling and simulation will enable the optimization of the composite design. Electrical conductive composites for electromagnetic interference shielding and lightning strike protection will be investigated as well. In parallel, a life cycle assessment will be carried out to compare the eco-composites with the state-of-the-art materials.
