“…[10][11][12][13] Among several approaches investigated, the addition of nanoparticles (such as carbon nanofibre, carbon nanotubes and montmorillonite nanoclay) in the epoxy matrix has been proven to be the most promising in improving the fracture toughness as well as the interfacial bonding to delay the onset and propagation of cracks. [14][15][16][17][18] Addition of very small amount (0.1-to 0.5-wt% loading) of graphene nanoparticles (GnPs) has shown a significant improvement in mechanical properties of polymer-based composites. [19][20][21] GnPs can facilitate effective load transfer through the interfacial region of the composites.…”

Three‐point flexural fatigue behaviour and mode I interlaminar fracture toughness of the carbon fibre reinforced polymer composites (CFRPCs) modified by the addition of graphene nanoplatelet (GnP) were investigated. CFRPCs without any addition of nanoparticles were also tested as control samples. Fatigue life was characterized by the two parameter Weibull distribution function and predicted using the combined Weibull and Sigmoidal model. It was found that incorporation of very small amount (0.1%) of GnP in the epoxy polymer matrix improved mean and predicted fatigue life up to 155% and 190% (0.5 failure probability), respectively. The critical mode I interlaminar fracture toughness of the GnP reinforced composites was found up to 40% higher than the control samples. The improvement achieved by incorporating GnP is discussed in terms of crack deflection mechanism by nanoparticles and scanning electron micrograph images of the fracture specimens that revealed strong interfacial bonding in the nanoreinforced specimens.

“…MMT/carbon samples showed increments of 49.7% and 16.9% in specific strength and modulus, respectively, compared to the neat carbon samples. The GNP/carbon and binary MMT/GNP/carbon also showed a significant improvement in specific strength and modulus compared to the unmodified carbon samples (figures 8,9,10). Nanoparticles improve the interfacial bonding between fiber and matrix.…”

“…However, the cost of graphene is higher than other nanomaterials that are being used commonly for FRPC materials. Less expensive organic materials like nanoclay is also popular as secondary reinforcement for FRPC materials [8][9][10]. Optimum enhancement in thermal and mechanical properties was achieved in case of 2 wt% of nanoclay addition [11].…”

Fiber reinforced polymer composite (FRPC) materials are superior to other conventional materials because of their high strength to weight ratio, corrosion resistance, and moisture resistance. FRPC materials are preferred in many high-end applications such as marine, automobile, aerospace, and advanced sporting goods. The aim of this study was to investigate the in-plane quasi-static compressive and durability studies of nanophased FRPC materials. Composite samples were fabricated using unmodified epoxy and epoxy modified with montmorillonite nanoclay (MMT), graphene nanoplatelets (GNP), and a combination of the two as a binary reinforcement with carbon fibers. Quasi-static compression tests were conducted for mechanical property evaluation. Seawater conditioning was performed for a six-month period both at room and arctic cold temperatures. The results indicated that addition of GNP and MMT improved the compressive properties of carbon/epoxy composites compared to unmodified carbon samples. Specific compressive strength and modulus of GNP infused samples improved by 30 and 41% respectively; the samples showed a relatively higher strain to failure than the unmodified samples. Specific compressive strength and modulus increased by 32 and 47%, respectively, for carbon/epoxy samples with MMT reinforcement. Performance of hybrid carbon/ glass/epoxy composites was lower compared to other FRPC materials considered in the study. The mode of failure of fractured samples investigated using scanning electron microscopy (SEM) showed a rough morphology after incorporation of nanoparticles into the polymer matrix. This is indicative of enhanced interfacial bonding between carbon/epoxy and the nanoparticles.

“…Even a small percentage of nanoparticle addition significantly influences mechanical properties of FRPC materials [5]. The degradation of FRPC materials depends on the nature of the environment and the unique responses of the constituents [6]. A great deal of research has been focused on the durability of FRPC materials that are subjected to extreme environmental conditions such as ultraviolet radiation (UV), seawater, salt-fog spray, or a combination of both.…”
