The aim of this project is the replacement of traditional mineral oil based plastics with innovative bio-based resin systems for aeronautical applications. Due to the high quality requirements of this field this challenge is much larger than in other industrial segments, therefore the use of functionalized plant oils alone as bio-components of matrices in aeronautical composites is not enough. According to our concept flame retarded special hybrid thermosetting polymer system has to be prepared using bio-based components. Innovative combination of new ideas of resin synthesis including click chemistry and sol gel reactions (providing flexibility of organic component balanced with hardness and thermal stability of the inorganic component), patented environmentally friendly reactive flame retardant components and modification of natural fibre by (patented) organic chemical and/or enzymatic method will result in bio-based epoxy composites of highly enhanced performance. The knowledge of a recently patented idea will be adapted to improve the recyclability of thermosetting bio-composites. The robustness of the technology will be ensured by process controlled reactors equipped with unique spectrometric feedback. The team of proposers includes various research groups of Budapest University of Technology and Economics (BME), whose activities (preparative green chemistry, enzymatic reactions, reactive fire retardancy, hybrid bio-composites, and innovative structural and mechanical evaluation) complete each other. The experiences of the proposers acquired in realization of another current CleanSky project represent a good starting point for achieving the required scientific and technical quality.
