Description
This project focused on pyrolytic recycling of carbon fibres from composite materials. A non-woven made of cut-off fibres was used as reinforcing agent for the production of hot pressed panels with three different matrices: epoxy, PA66/6I, and PA66/6I with flame retardant. the matrices were compared both for their mechanical properties and for their influence on recycling. It was demonstrated in this work that carbon fibres from both thermoset and thermoplastic matrices can be successfully recycled through a common process, yielding fibres with similar properties. Importantly, PA66/6I shows potential qualitative advantages in re-manufactured properties, likely due to a stronger interaction with the recycled carbon fibre surface. The addition of an organic aluminum phosphinate helps with the retention of fibre properties and yield more consistent mechanical performance over the whole recycling process.| Period | 2025 |
