“…Due to this, tensile and flexural properties are less for GFE-0 than other composites. From FESEM images, it is monitored that good dispersion and bonding of GNP nanofiller in carbon fiber, and epoxy matrix in the case of GFE-3 and GFE-5 samples enhance the mechanical strength of these hybrid nanocomposites [16]. Figure 7 shows the EDS mapping of all the composites.…”

In this research, carbon fiber and Graphene nanoplatelets (GNP) of different weight percentages of GNP (0, 0.1,0.3, and 0.5 wt.%) reinforced hybrid composites were fabricated via hand layup technique followed by compression molding. For wear analysis to understand the correlation between control parameters (wt.% of filler, normal load, velocity, and sliding distance) and response measurements (weight loss), the design of experiments and analysis of variance (ANOVA) is used. The control variables such as normal loads (5, 10, 15, and 20 N), velocity (1,2,3 and 4 m/s), and sliding distance (200, 300, 400, and 500 m) are selected for the research. It was observed that 0.5wt.% GNP-filled carbon fiber/epoxy composite shows higher tensile and flexural strength than another composite. It has been discovered that adding GNP reduces the wear in terms of weight loss. Scanning electron microscopy (SEM) was used to examine composites' worn surfaces. The analysis concluded that experimental results are closer to optimum results.

“…Other groups have also reported similar behaviors (Seretis et al, 2017;Wang et al, 2016b;Topkaya et al, 2020;Jena et al, 2020;Turaka et al, 2021); namely, the flexural properties got improved, followed by weakened with increasing GNP additions, as a small amount of GNPs could contribute to chemical bonding, mechanical anchoring, and interlocking between the interfaces (Pathak et al, 2016;Moaseri et al, 2014), which strengthened the composites under bending. However, the formation of GNP networks under high loadings (Figure 5D) accelerated the delamination and decreased the stress transfer efficiency (Kamar et al, 2015;Umer, 2018), thus weakening the composite performance.…”

“…To improve the bending properties of the composites, nanomaterials have been introduced to strengthen the matrix and interface. Graphene and its derivatives have been extensively studied since its first isolation in 2004 (Novoselov et al, 2004) and widely applied into fiberreinforced polymer composites (Kamar et al, 2015;Qin et al, 2015;Wang et al, 2016a;Wang et al, 2016b;Mahmood et al, 2016;Monfared Zanjani et al, 2016;Pathak et al, 2016;Du et al, 2017;Jiang et al, 2017;Kwon et al, 2017;Prusty et al, 2017;Wang et al, 2017;Zhang et al, 2017;Umer, 2018;Yao et al, 2018;Jena et al, 2020;Topkaya et al, 2020;Vigneshwaran et al, 2020;Turaka et al, 2021), owing to their outstanding mechanical, electrical, and thermal properties. In particular, graphene nanoplatelets (GNPs), which are comprised of 10s of graphene layers, can be mass-produced by various techniques, including ball-milling, chemical exfoliation, thermal exfoliation, etc.…”

Fabrication and Mechanical Performance of Graphene Nanoplatelet/Glass Fiber Reinforced Polymer Hybrid Composites

Glass fiber reinforced polymer (GFRP) composites are promising alternatives for the traditional carbon steel pipes used in the oil and gas industry due to their corrosion and chemical resistance. However, the out-of-plane mechanical properties of GFRPs still need further improvement to achieve this goal. Hence, in this work, two methods combining either vacuum mixing or spray coating with vacuum-assisted resin infusion were studied to fabricate graphene nanoplatelet (GNP)/GFRP hybrid composites. The former method resulted in a severe filtering effect, where the GNPs were not evenly distributed throughout the final composite, whereas the latter process resulted in a uniform GNP distribution on the glass fabrics. The addition of GNPs showed no modest contribution to the tensile performance of the GFRP composites due to the relatively high volume and in-plane alignment of the glass fibers. However, the GNPs did improve the flexural properties of GFRP with an optimal loading of 0.15 wt% GNPs, resulting in flexural strength and modulus increases of 6.8 and 1.6%, respectively. This work indicates how GNPs can be advantageous for out-of-plane mechanical reinforcement in fiber-reinforced composites.

“…Such materials can be called "hybrid" reinforced composites. [16][17][18][19] It was also investigated the ways to improve the electrical conductivity of CFRPs for aircraft applications where high functional properties are eligible. One approach is the addition of metal particles: silver, [20,21] copper, [22] tin, [23] spherical shaped, [22] in the shape of fibers.…”

Hybrid composite materials reinforced with unidirectional fibers and small-scale micro-or nanoparticles provide benefits compared to traditional composites. The present paper shows the experimental investigation of carbonfiber-reinforced polymers modified by the addition of 0.5-5 wt% of milled carbon fibers and 0.1-0.5 wt% of single-wall carbon nanotubes. Both fillers were analyzed from technological point of view. The impact on mechanical and physical properties was revealed and discussed. Main attention was paid to quasi-static tensile and flexural properties as well as fatigue behavior under tension-tension mode. The maximal improvement in static tensile strength by 8.6% (from 682 to 741 MPa) and flexural strength by 14% (from 649 to 740 MPa) was achieved by the addition of 0.3 wt% single-wall carbon nanotubes. Short beam shear strength increased by 18%. Fatigue durability was highly improved as well. The strengthening mechanisms are attributed to the improvement of shear interfacial properties. In contrast to single-wall carbon nanotubes, milled carbon fibers enhanced the properties by 3%-9% only at static loading, while fatigue properties are negatively affected.
