Upon comparison between the mechanical properties of composites with EEG and EEA, we observed that the delamination was significantly reduced with the addition of the aminefunctionalized graphene. As the amine groups could react with the epoxy rings and form covalent bonds, and strengthen the interfacial properties. As a result, the tensile and flexural strength of EEA composites improved by 17.6% and 5.4% respectively compared with the control composites, with only 0.5 wt.% EEA flakes spray coated onto the carbon fibres.
