Fibre reinforced polymers are important materials used in aviation due to their excellent specific properties enabling the reduction of fuel consumption. For example, carbon fibre reinforced epoxy resins are used in fuselage and wing structures. Glass fibre reinforced phenolic resins are mainly used for the interior panels due to their low weight and favourable fire properties. All these composite materials used 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 for composites but they did not made it into modern aircraft in high amounts yet. The project ECO-COMPASS under Horizon 2020 aims to bundle the knowledge of 19 partners from China and Europe to develop ecological improved composites for the use in aircraft interior and secondary structures. Bio-based reinforcements, epoxy resin and sandwich cores are developed and improved for their application in aviation. Furthermore the use of recycled carbon fibres to increase the mechanical strength and multifunctional aspects of bio-composites are evaluated. In order to withstand the special stresses in aviation environment, protection technologies to mitigate the risks of fire, lightning and moisture uptake are under investigation. An adapted modelling and simulation will enable the optimization of the composite design. Electrical conductive composites for electromagnetic interference shielding and lightning strike protection are under investigation in ECO-COMPASS as well. The cooperation includes the exchange of knowledge and materials in order to optimize the development of ecological friendly composites. The aim of the presentation at the ICSI2019 conference is to give an overview of the project objectives and its special background with the collaboration of Chinese and European partners. Selected topics and final results of the ECO-COMPASS project will be presented.

Fibre reinforced polymers (FRP) are important materials used in aviation due to their excellent mechanical properties combined with relatively low weight enabling the reduction of fuel consumption. For example, expensive carbon fibre reinforced epoxy resins are used in fuselage and wing structures.

Composites are important materials used in aviation due to their excellent mechanical properties combined with relatively low weight enabling the reduction of fuel consumption. Expensive carbon fibre reinforced epoxy resins are used in fuselage and wing structures and increasingly compete with classic metals. Glass fibre reinforced phenolic resins are mainly used for the interior panels due to their low weight and favourable fire properties. All these composite materials used 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 for composites but they did not made it into modern aircraft in high amounts yet.

To assess the environmental impacts a Life Cycle Assessment will be carried out to compare the new eco-composites with the state-of-the-art materials. The aim of the presentation at the Greener Aviation 2016 conference is to give a short overview of the project objetives and it's special background with the collaboration of Chinese and European partners. Selected topics of the ECO-COMPASS project will be presented in more detail with first results from the technical work-packages on different types of fibre-reinforcements, bio-sourced resins, core-materials and possible application in aviation interior and secondary structures with their different challenges for ecological improved materials.

Introduction of bio-composites into aircraft interior and airframe secondary structures is subjected to major technical challenges such as the enhancement of mechanical, thermal, electrical and electromagnetic shielding properties of bio-sourced materials. In this paper, electrical conductivity and electromagnetic shielding effectiveness of two bio-composites have been studied by tests and numerical models. Two monolithic composites with partly bio-based content were manufactured. The first bio-composite is made of a carbon fibre fabric prepreg and a partly bio-based (rosin) epoxy resin (CF/Rosin). The second bio-composite is a combination of prepregs of carbon fibre fabric / epoxy resin and flax fibre fabric / epoxy resin (CF-Flax/Epoxy). A single line infusion process has been used prior to the curing step in the autoclave. Both variants are exemplary for the possibility of introducing bio-based materials in high performance CFRP. In-plane and out-of-plane electrical conductivity tests have been conducted according to Airbus standards AITM2 0064 and AITM2 0065, respectively. Electromagnetic shielding effectiveness tests have been conducted based on the standard ASTM D 4935-10. Materials were prepared at the German Aerospace Center (DLR) while characterization tests were conducted at the University of Patras. In addition to the tests, numerical models of representative volume elements have been developed using the DIGIMAT software to predict the electrical conductivity of the two bio-composites. The preliminary numerical results show a good agreement with the experimental results.
