Influence of lignins on processing and surface features of bio-based carbon fibres from Melt-Spun Lignin/TPU precursors

Key Points

• Bio-based carbon fibres demonstrated improved surface features when processed with lignins, enhancing performance.
• Key evidence revealed that lignin incorporation increased the tensile strength of the resulting fibres by 15% over conventional methods.
• Analysis focuses on melt-spun lignin and thermoplastic polyurethane (TPU) precursors to assess processing techniques.
• Highlights the potential of lignins to optimize the properties of bio-based carbon fibres for industrial applications.
