AbstractIn this paper, the effect of Single Walled (SWNT) and Multi Walled Carbon Nanotubes (MWNT) as a toughening agent of laminated composites is experimentally investigated. Carbon fibre laminates were manufactured by resin film infusion and prepreg manufacturing techniques. A maximum of 140% improvement was achieved in the Mode I delamination properties of the CNT-modified epoxy composite compared with the baseline composite material. In contrast, this improvement was not observed for the nano-modified polymers used to manufacture the composite laminates. A qualitative analysis of the fractured surface using a Scanning Electron Microscope revealed a good dispersion in the composites samples, confirming the importance of processing to harness the full potential of carbon nanotubes for toughening polymer composites.
