“…The development of Al carbide described the inferior mechanical characteristics of the composite during the consolidation and subsequent heating and extrusion phase. In 2012, Wang et al recorded aluminum composite strengthened with graphene Nano-layers using peel powder metallurgy [52]. The impact on tensile strength of aluminum composite was only 0.3 wt% GNS is 249 MPa.…”

Two-dimensional (2D) graphene and its outstanding properties such as, enormous conductivities, mechanical strength, optical and electrical properties brought it one of the most studied materials for the production of energy using renewable resources. The composites of graphene with the same morphological materials such as layered transition metal oxides will be the most aspiring combination to boost their conducting, optoelectronic and mechanical properties. Furthermore, the transition metal chalcogenides materials attracted significant attention due to their atomically thin layers and enormous optical, conducting and electrical properties. The layered materials offer mostly atomically thin 2D plane to the charge carrier with superior conducting properties. The thickness at atomic level, band gap, spin orbit coupling electronic and optoelectronics properties of transition metal dichalcogenides makes them one of the promising entities in energy harvesting technologies. The review suggests some strategies to improve the transition metals-composites stability conducting properties to be tailored in various applications.

“…Much research on graphene reinforced aluminum matrix composites (GRAMCs) has been conducted to improve the low mechanical strength and the thermal and electrical properties of raw Al. The uniform dispersion of fillers and good interfacial interaction between additives and the matrix materials are important factors influencing the enhancement of characteristics by combining with the Al matrix and carbon fillers [11][12][13].…”

Graphene Encapsulated Al Particles for Improvement of Thermal Conductivity in Composites

Graphene reinforced aluminum matrix composites (GRAMCs) with improved thermal conductivity were prepared via a pH-controlled self-assembly process that involved adjusting the concentration of dispersed graphene oxide (GO) solutions. Uniform dispersion was achieved using GO coating on the aluminum (Al) surfaces. Graphene encapsulated Al powders (Al/GO) were sintered through spark plasma sintering (SPS) to prepare bulk composites, these were then analyzed to determine the thermal and mechanical properties. The density of the Al/GO composites was determined to be 99% or more compared to the theoretical density of pure Al. The Vicker’s hardness and thermal conductivity increased by about 47% and 15% more than the pristine Al bulks. These processes can improve properties of the thermal interface between GO and Al, enabling uniform coating without a crosslinking agent. An Al/GO composite, fabricated through the pH-controlled self-assembly process, should be useful for various applications requiring to high thermal conductivity.

“…At present, there are still some problems in the fabrication of graphene-reinforced Al composites, such as how to disperse the graphene uniformly in the Al matrix [ 24 , 25 ], how to reduce the interfacial reaction between graphene and the Al matrix [ 26 ], and how to solve the wettability problem between graphene and the Al matrix [ 27 ]. Among these problems, achieving a uniform dispersal of graphene in the Al matrix without destroying the integrity of graphene nanoplate is the primary problem that can determine whether the enhancement effect of graphene can be fully utilized.…”

Aluminum composites reinforced by graphene nanoplates(GNP) with a mass fraction of 0.5% (0.5 wt.% GNP/Al) were fabricated using cold pressing and hot pressing. An orthogonal test was used to optimize the fabrication parameters. Ball milling time, ball milling speed, and ultrasonic time have the largest influence on the uniformity of the graphene in the composites. Afterwards, the microstructure, interfacial properties, and fracture morphology of the composites obtained with different parameters were further analyzed. The results show that ball milling time and ball milling speed have obvious influences on the mechanical properties of the composite. In this paper, when the ball milling speed is 300 r/min and the ball milling time is 6 h, the dispersion uniformity of graphene in the 0.5 wt.% GNP/Al composite is the best, the agglomeration is the lowest, and the mechanical properties of the composites are the best, among which the tensile strength is 156.8 MPa, 56.6% higher than that of pure aluminum fabricated by the same process (100.1 MPa), and the elongation is 19.9%, 39.8% lower than that of pure aluminum (33.1%).
