“…15 are indicative of the pull-out of aggregated clay particles. When the nanocomposite samples were tested under flexural loading, cracks might have initiated at the aggregated clay particles and propagated throughout the samples [29,30]. Therefore, the flexural strength of the single-additive nanocomposites was lower at higher clay contents.…”

“…[6][7][8] These nano-scaled filler modifiers produce high-performance composite structures with enhanced properties as they offer increased surface area for loading volume fraction of nano-scale fillers and achieve improvements in the properties at a very small weight fraction. 9 Graphene-based materials, such as graphene nanoplatelet, graphene nanosheets, and graphene oxide, show a greater extent to improve the properties of polymers due to high aspect ratio, high mechanical, thermal, and electrical conductivity etc. 10,11 Recent research has stimulated considerable interest in the range of graphene oxide/polymer nanocomposites.…”

ABSTRACT:The present work has the objective of fabricating graphene oxide (GO) and amine-functionalized graphene oxide (F-GO) reinforced epoxy composites using the casting method. Epoxy resin was dispersed separately with GO (0.5 wt%) and F-GO (0.5 and 1 wt%), and then the epoxy resin mixture cured with triethylenetetraamine at room temperature. The synthesized GO and F-GO were characterized by FT-IR and Raman spectroscopy. The interfacial interaction of Si in the composite was studied by XPS. The formation of GO and F-GO was confirmed by XRD. The tensile and flexural strength composites were measured using the UTM. The thermal behavior and dynamic mechanical behavior were examined by TGA and DMA. The surface morphology and dielectrical properties were analyzed by SEM, TEM, and impedance analyses. The results obtained from epoxy/F-GO (0.5 wt%) composite revealed higher mechanical and thermal properties than neat epoxy and epoxy/GO composites.

“…Nano-phased matrix based on organic polymers and inorganic clay minerals consisting of silicate layers have attracted great interest because they frequently exhibit unexpected properties including reduced gas permeability, improved solvent resistance, superior mechanical, and enhanced flame-retardant properties [10][11][12][13][14][15]. Different polymer/clay nanocomposites have been successfully synthesized by incorporating clay in various polymer matrixes such as, polyamides [16], polyimides [17], epoxy [18], polyurethane [19], poly(ethylene terephthalate) [20], and polypropylene [21]. These polymerbased nanocomposites derive their high properties at low filler volume fractions due to the high aspect ratio and high surface area to volume ratio of nanoclay.…”

In this study, dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and flexural tests were performed on unfilled, 1, 2, 3, and 4 wt% clay filled SC-15 epoxy to identify the effect of clay weight fraction on thermal and mechanical properties of the epoxy matrix. The flexural results indicate that 2.0 wt% clay filled epoxy showed the highest improvement in flexural strength. DMA studies also revealed that 2.0 wt% system exhibit the highest storage modulus and T g as compared to neat and other weight fraction. However, TGA results show that thermal stability of composite is insensitive to the clay content. Based on these results, the nanophased epoxy with 2 wt% clay was then utilized in a vacuum assisted resin transfer molding set up with carbon fabric to fabricate laminated composites. The effectiveness of clay addition on thermal and mechanical properties of composites has been evaluated by TGA, DMA, tensile, flexural, and fatigue test. 5°C increase in glass transition temperature was found in nanocomposite, and the tensile and flexural strengths improved by 5.7 and 13.5 %, respectively as compared to the neat composite. The fatigue strength was also improved significantly. Based on the experimental result, a linear damage model combined with the Weibull distribution function has been established to describe static failure processing of neat and nanophased carbon/epoxy. The simulated stress-strain curves from the model are in good agreement with the test data. Simulated results show that damage processing of neat and nanophased carbon/ epoxy described by bimodal Weibull distribution function.
