Three different types of hybrid composite laminates were prepared from untreated and GNP-coated glass and carbon fabrics, and epoxy resin. Two concentrations (1 and 5 wt.% ) of GNP dispersion were used to coat the fabric. Glass/epoxy and carbon/epoxy composites were also manufactured for baseline specimens. Tensile test results of different composites are presented in Table . Fig. shows the tensile stress-strain response of the neat carbon/epoxy and glass/epoxy composites laminates. Both carbon and glass fabric composites show a catastrophic failure. The tensile stress of the glass and carbon fibre composites was found to be ~454 and ~568 MPa, and the tensile strain was found to be ~3.26 and ~1.29%, respectively. Stress-strain responses of untreated glass-carbon/epoxy and GNP-coated glass-carbon/epoxy hybrid composites are shown in Fig. . Images at different strain levels during the tensile tests (recorded using a high-speed video camera) are also shown on the right side of the respective graphs (i-iv). All the hybrid composites demonstrate non-linearity in their stress-strain graph instead of a sudden catastrophic failure. There was no load drop after the initial failure of the carbon layer, and a smooth transition of stress after carbon fibre failure was observed. As carbon fibre has a lower strain to failure compared to that of glass, therefore carbon fibres failed initially. Once the carbon fibres failed, the stress was redistributed to the high-strain glass fibres that carried the load to ultimate failure. A significant variation of the pseudo-ductile properties of GNP-coated glass-carbon/epoxy hybrid composites was observed compared to untreated glasscarbon/epoxy hybrid composite.
