The multifunctional enhancement of carbon fibre-reinforced polymers (CFRPs) is critical for their expanding applica tions in aerospace, automotive, and electronics industries. This study examines the combined effect of thermoplastic veils doped with multi-walled carbon nanotubes (MWCNTs) and a polymer matrix modified with single-walled carbon nanotubes (SWCNTs) on the mechanical, thermal, and electrical properties of CFRPs. Liquid thermoplastic acrylic resin Elium®, modi fied with 0.02 wt.% SWCNTs served as the matrix, while thermoplastic veils based on polyphenylene sulphide (PPS) and polybutylene terephthalate (PBT) doped with 1.0 wt.% MWCNTs were interleaved into the composite structure. Characteri sation revealed that the SWCNTs formed conductive networks in the polymer matrix, enhancing electrical conductivity in plane (X and Y directions) but not improving it through the thickness (Z direction) due to resin-rich regions introduced by the veils. The impact resistance improved across all the composites, particularly for the PPS-based veils, attributed to effective fi bre bridging mechanisms. The glass transition temperature (Tg) also increased due to strong adhesion at the veil-matrix inter face and molecular interactions between the nanofillers and the polymer matrix. The results highlight the potential of combin ing nanofiller-modified matrices with thermoplastic veils to achieve tailored multifunctional CFRPs. However, optimising the interlayer resin content remains crucial for further enhancing through-thickness conductivity. These findings contribute to advancing CFRPs for high-performance, multifunctional applications in diverse industries.
