The main objective of ELECTRICAL was the development of novel multifunctional composite structures with bulk electrical conductivity and self-sensing capabilities for rapid non-destructive quality assessment. The project properly exploited the excellent properties of CNTs as polymeric resin doping for the development of novel multifunctional composite structures with bulk electrical conductivity and self-sensing capabilities. ELECTRICAL investigated and developed alternative emerging methods to manufacture nanoreinforced carbon based composites compatible with current industrial manufacturing processes of composites: incorporation of nanofillers into toughening thermoplastic fibres, non-woven veils, incorporation of nanofillers into nanostructured preforms called buckypapers, incorporation of nanofillers in injection resin and carbon fibre prepregs.

Development of a melt-blown process for the production of non-woven thermoplastic veils with up to a 5,5% CNT content. Structural characterization of non-woven veils with different CNT content and different surface functionalization, as well as assessment of their functionality. Mathematical modelling of the conductivity of the composites as a function of spatial distribution of CNT and functionalization of their surfaces. Development of FEM parametric models of conductivity taking into account the percolation threshold for specific dispersion/architecture of CNT. Manufacturing of the engineered structures.
