Circularity studies on high performance thermoplastic demonstrators for the aircraft industry – End-of-Life concepts for PEKK/carbon fiber

Abstract In this study, the circularity of different end-of-life concepts for PEKK reinforced with high performance carbon fiber composite parts were investigated. For this, two thermoplastic demonstrators from Clean Sky 2’s ecoTECH Project used. Recycling and components demonstrated by scraping continues fuselage panel into small flakes, which then to be re-used as short particles produce compression molded Window Frames. scraping, technologies compared means quality, efficiency environmental impacts. Based on recycling re-use options both Frame demonstrators, Linear Flow Index (LFI) Material Circularity Indicator (MCI) parameters calculated used showcase alternative levels each scenario
