Description of the project offered Exponential growth of carbon fibre reinforced plastics (CFRP) consumption and new EU Waste Framework Directive push the problem of CFRP recycling to the forefront. Today 3 appropriate competitive technologies for carbon fibres recovery during CFRP recycling are available at EU market at the different TRL: • low-temperature pyrolysis (Recycled Carbon Fibre Ltd.) • wet-chemical treatment (Adherent Technologies Inc.) • solvolysis in supercritical fluids (AFRECAR and EURECOMP projects) Currently all these processes use grinded CFRP waste to generate short carbon fibres for further usage in non-critical low-loaded structures. Mentioned processes specific disadvantages are recovered fibres characteristics degradation + non-uniformity, low productivity, toxic chemical agents application, and equipment complexity. Project basic idea is application of high-temperature pyrolysis in the salt melts as an alternative approach for carbon fibres recovery. Project goal is to save maximum possible fibre length and reach ≈100% recovered fibres performances to ensure their reuse in secondary (medium loaded) aeronautic/automotive structures. National Aerospace University "KhAI" preliminary research results have demonstrated potential benefits of prospective carbon fibres recovery technology based on the high-temperature pyrolysis in the salt melts: • high process productivity ( 99% fibre cleaning after 20-60 second treatment) • minimal fibre characteristics degradation; • process flexibility (short/continuous fibres, large fabric pieces recovery) • applicability for out-of-life prepreg rolls direct recovery • energy efficiency As a result of CEFIR project high-competitive technology can be created for growing market.
