Increasing the electrical conductivity of the Carbon Fibre Reinforced Polymers (CFRP) is achieved by incorporation of highly conductive nanofillers such as carbon nanotubes, graphene oxide or graphene nanoplatelets by different technical approaches. Most of these methods require direct contact with the powdered nanoparticles and are appropriate only for the small production scale. An innovative way to improve the electrical conductivity of CFRP has been developed by introducing thermoplastic nonwovens containing multi-walled carbon nanotubes, called CNT-doped veils, into their structure. This nano-enabled product is manufactured by a half industrial pilot line from different types of low and high temperature thermoplastic polymers compatible with epoxy and polyester resins. CNT-doped veils are characterised by high flexibility, easy handling and eliminate working with the powder nanoparticles by the end-users. Incorporation of CNT-doped veils between CFRP layers or as surface finishing resulted in an increase of electrical conductivity, especially though the thickness, but also improved the mechanical performance due to the presence of a small amount of thermoplastic polymer. The funding for this research was provided by the European Union’s Horizon 2020 research and innovation program under GA 646307 “PLATFORM” and GA 814581 “OASIS”.
