Paragraph starter

The manufacturing of thermoplastic fibre-metal laminates (TP-FML) is significantly influenced by the interfacial bonding between the metal and composite layers. Research by Mamalis et al. (2018) demonstrates that applying specific surface treatments to the metal components prior to vacuum resin infusion can dramatically enhance this interfacial adhesion. This improved bonding, often evidenced by increased shear strength and reduced delamination, is attributed to better wettability of the metal surface by the thermoplastic resin. Therefore, careful consideration and optimization of surface preparation techniques are critical for achieving the desired structural integrity and performance in TP-FML applications.
