“…For instance, tensile strength values ranging between 240 and 280 MPa have been reported in some studies where Gr‐reinforced metal matrix composites were prepared especially using Gr and aluminium, underlining the impressive mechanical reinforcement achieved through graphene incorporation [104,105] . On the other hand, alternative investigations have also observed tensile strength levels reaching up to 110 MPa, showcasing the versatility of Gr structures in manipulating the nanocomposite‘s mechanical behaviour [106,107] …”

The expansion of nanofiller‐based polymers has been rapidly increasing in contemporary society due to their wide range of applications owing to their diverse physicochemical characteristics. This review focuses on a polymer nanocomposite in which graphene is incorporated as a nanofiller and polyurethane is used as a polymer. As polyurethane is well known for its shape memory behaviour and the reinforcement of graphene‐based nanomaterial sparks the physicochemical properties of the fabricated nanocomposites which makes it more adaptable and useful for a wide array of applications. The review provides insights into the recent synthesis approaches to the fabrication of graphene‐based polyurethane nanocomposites. Further, efforts were also made to cover the recent studies done on the use of these nanocomposites as an advanced shape memory material. Rather than merely serving as descriptive content, this article is intended to serve as a comprehensive guide for researchers seeking to harness the potential of graphene‐based nanomaterial reinforcement in polyurethane for high‐performance applications. By providing a detailed overview of the latest research in this domain, the review aims to propel the development of novel and sophisticated materials, unlocking new horizons in smart shape memory technologies.

“…However, the atomic percentage is still large due to the low mass of the carbon atom. Many researchers believe that the optimal value of graphene is between 0.3-1.0 wt% [16], and it seems to be an interesting topic to further investigate the effect of content for graphene.…”

“…Second, BM process and the addition of 3DGN refined the aluminum grains, thus increasing the grain boundary, which can prevent the movement of the dislocations in the matrix material. Finally, as the sintering temperature increases, the thermal stress leads to the formation of dislocations at the matrix-reinforcement interface due to a thermal expansion mismatch between the aluminum matrix and the 3DGN reinforcement [16]. However, further addition of 3DGN is detrimental to the Vickers hardness.…”

Three-dimensional graphene networks (3DGN) have the potential to be used as a reinforcement for aluminum matrix composites due to their unique wrinkled structure and cost-effectiveness. In this work, the mechanical properties and corrosion resistance of 3DGN in Al matrix were systematically investigated. 3DGN/Al composites with weight ratios of 0, 0.075, 0.150, 0.225, and 0.300 3DGN were prepared by powder metallurgy following by ball mill and spark plasma sintering. Results revealed that the densification of 3DGN/Al composites slightly decreases with the increase of 3DGN content. Increased hardness without loss of ductility was recorded compared to the pure aluminum sample prepared under the same experimental conditions. 3DGN/Al composites exhibit higher corrosion currents density than that of pure aluminum, which shows that the addition of 3DGN reinforcement aggravates the corrosion of aluminum. This study can be used as a reference for future research on the effect of graphene on the various properties of graphene-reinforced aluminum matrix composites.

“…The addition of reinforcement such as silicon carbide (SiC) [ 5 , 6 ], boron carbide (B 4 C) [ 7 ] alumina oxide (Al 2 O 3 ) [ 8 ] are common in AMC while graphene [ 9 , 10 ] and carbon nanotubes (CNTs) [ 11 , 12 , 13 , 14 ] which are made up of carbon-based nanomaterials, have attracted tremendous attention for AMC. Graphene nanoplatelets (GNPs) have become an excellent reinforcement because of their superior mechanical, thermal and electrical properties [ 15 , 16 , 17 ] as compared with CNTs.…”

Thixoforming is a promising method that offers several advantages over both liquid and solid processing. This process utilizes semi-solid behaviour and reduces macrosegregation, porosity and forming forces during the shaping process. Microstructural and mechanical characterization of 0.3, 0.5 and 1.0 wt% graphene nanoplatelet (GNP) reinforced A356 aluminium alloy composite fabricated by thixoforming was investigated. Stir casting was employed to fabricate feedstocks before they were thixoformed at 50% liquid. The microstructure was characterized and evaluated by field emission scanning electron microscopy with an energy dispersive X-ray detector and X-ray diffraction. Mechanical testing, such as microhardness and tensile testing, was also performed to estimate the mechanical properties of the composites. The incorporation of 0.3 wt.% GNPs in Al alloy increased by about 27% in ultimate tensile strength and 29% in hardness. The enhancement in tensile strength is primarily attributed to load transfer strengthening due to the uniform dispersion of these GNPs within the Al matrix, which promotes effective load transfer during tensile deformation, and GNPs’ wrinkled surface structure. Simultaneously, the addition of GNPs enhances the grain refinement effect of the Al alloy matrix, resulting in a grain size strengthening mechanism of the GNPs/Al composites. The results reveal that thixoformed composite microstructure consists of uniformly distributed GNPs, α-Al globules and fine fibrous Si particles. The composites’ grains were refined and equiaxed, and the mechanical properties were improved significantly. This study creates a new method for incorporating GNPs into Al alloy for high-performance composites.
