| Carbon nanofibres (CNFs) were used as modifiers for epoxy resin (EP). The main target was to increase the electrical conductivity of the neat EP and develop materials appropriate for antistatic and static dissipation applications. The percolation threshold, Vc, of the materials was determined approximately in the range 0.5< Vc<1 wt.% of CNFs. Both tensile modulus and strength were increased by the incorporation of the nanofibres in the epoxy compared to the neat matrix. Moreover, some preliminary tests were performed for the in-situ monitoring of the electrical conductivity changes during loading of the nanocomposites. |
