Abstract: 3-point flexural fatigue, interlaminar fracture and viscoelastic performance of graphene nanoplatelet (GnPs) reinforced carbon fiber reinforced epoxy composites were studied. An amount of 0.1 wt.% of GnPs were mixed with part A of an epoxy resin system using sonication method followed by magnetic stirring. Further, a 3-roll shear mixing was used to complete the dispersion process. GnPs included part A of the resin system was mechanically mixed with part B and then used to fabricate carbon fiber reinforced epoxy composites. Mode I fracture toughness interlaminar fracture test was performed per ASTM D5525-13 standard. Both static and fatigue flexural studied were carried out at stress ratios of 0.9, 0.8, 0.75 and 0.7 following ASTM D790-03 and ASTM D7774-17 standards, respectively. Dynamic mechanical analysis (DMA) was also performed following ASTM D4065-12 standard. It was found that incorporation of very small amount (0.1%) of GnP in the epoxy matrix improved mean flexural fatigue life up to 155%. The critical mode I interlaminar fracture toughness of the GnP reinforced composites was found up to 40% higher than the control samples. In DMA test, GnP reinforced samples demonstrated 11% and 17.8% higher storage and loss modulus, respectively. Scanning electron microscopy (SEM) of the fracture surfaces revealed strong interfacial bonding in the nano-reinforced specimens.
