“…This is evident from the earlier research studies, the tensile load exerted on the composite transferred to the carbon nanotube thereby pulling leads to bending in nanotubes and break in the form of telescopic sheath [33,34]. The effective dispersion and better interfacial bonding between the matrix and the varied fraction of MWCNTs enhanced the UTS as reported by the others [35,36].…”

In this research paper, Multiwalled carbon nanotubes (MWCNTs) reinforced with Al2024 were ball milled for homogenization of powder. Nanocomposite was developed using MWCNT reinforcement having 0.5%, 1.5%, and 2.5% weight percentage mixed with Al2024 by powder metallurgy technique. Samples were compacted using a hydraulic press and sintered. Further, sintered samples were solutionized by heating at 560º C followed by quenching and ageing, to

“…But the combination of graphene/MWCNT processed through ball milling leads to breaking of MWCNT clustering, flattening, and embedding on the aluminum particulate through plastic deformation. In addition, during ball milling, graphene flakes get flattened and become a monolayer, and interatomic distance between carbon atoms will increase and get packed by matrix atoms [50,51]. It is inferred that upon addition of graphene on aluminum and aluminum-graphene/MWCNT (flattened) combinations will give the least wear loss compared to monolithic, MWCNT, and aluminum-graphene/MWCNT (tubular) composites.…”

Graphene Materials - Structure, Properties and Modifications

Graphene is a new class of material in carbon group with strong sp 2 -hybridized 2D-sheet like nanomaterial. In order to make an effective utilization of their astounding properties, they are currently used in the form of reinforcements in various proportions in metals and its alloys to fabricate the nanocomposites. Graphene is incorporated in oil and grease at nano range that results in higher load-carrying capacity compared with that of raw grease and oils without additives, which shows that graphene possesses self-lubricating capacity. Graphene is a planar sheet-like structure (2D), with more contact surface area in the developed composites that can make them suitable for industrial applications with well-established tribological performance. The novelty of this work focuses on the role of graphene addition in enhancing the wear performance aluminum composites to replace the conventional materials by graphene composite combinations. The current chapter explains the processing and tribological performance of graphene-aluminum composites and its effect with various hybrid combinations of MWCNT/SiC/Al 2 O 3 . Dispersion of graphene is carried out through ultrasonic liquid processor followed by ball-milling aluminum powder. Thus prepared precursors are vacuum-pressed and microwave-sintered. Graphene in the nanocomposites has resulted in significantly improving the tribological properties, where it gives the wear resistance by creating a solid, lubricant layer between the sliding surfaces.

“…The authors from the study [45][46][47][48][49][50][51] indicate that the following methods are in use: hot rolling [45], sintering [46], plasma spray forming [47], stir casting [48], semisolid powder processing (SPP) [49], spark plasma sintering (SPS) [50] and spark plasma extrusion (SPE) [51]. The methods of intensive plastic deformation, equal channel angular pressing (ECAP) [52] and friction stir processing were also employed to manufacture such nanocomposite materials [53].…”

In this chapter, the characterisation of the halloysite nanotubes (HNTs) and multiwalled carbon nanotubes (MWCNTs) as the reinforcement in the composite materials was described. The original and author technology of production of the aluminium AlMg1SiCu matrix composite materials reinforced with halloysite or carbon nanotubes using powder metallurgy techniques, including mechanical alloying and hot extrusion and the range of own research in the case to determine microstructure, as well as mechanical properties of those materials was present. It was investigated that the addition of carbon and halloysite nanotubes causes a significant improvement in mechanical properties of the obtained nanocomposites. The investigation results show that the technology used in manufacturing nanocomposite materials can find the practical application in the production of new light metal matrix nanocomposites.
