The pseudo-yield stress and initial modulus of these composites were higher compared to uncoated glass-carbon/epoxy hybrid composites. The pseudo-yield stress of 1 and 5 wt.% GNP-coated composites was increased by ∼22.89% and ∼13.90%, respectively, compared to uncoated glass-carbon/epoxy hybrid composites. The highest modulus and maximum stress values were achieved with 1 wt.% GNP-coated glass-carbon/epoxy hybrid composites. Young's modulus increased by ∼17.05% and ∼11.52%, and ultimate failure stress increased by ∼18.52% and ∼9.72%, respectively, for 1 and 5 wt.% GNP-coated composites compared to that of glass-carbon/epoxy hybrid composite.
