Abstract:
Although many problems in aluminium matrix composites have been solved, there are still many difficulties and challenges that need to be solved. In this work, graphene reinforced aluminum matrix composites are prepared by hot isostatic pressing and vacuum sintering. The microstructures of composite powders and composites were studied by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effects of different ball milling parameters on the microstructures of composite powders were analyzed. The particle size of graphene coated aluminium composite powder increases with the increase of ball-to-material ratio. With the increase of milling time, graphene was gradually dispersed and coated on the aluminium powder particles, and the aluminium powder particles could be completely coated. with the increase of the speed, the large particles are extruded, sheared and the particles become smaller. The internal micro-deformation characteristics of graphene reinforced aluminium matrix composites were analyzed in detail.

Abstract:
Recently, many studies on the production of graphite/graphene reinforced aluminum-matrix composites using different fabrication methods, such as powder or semi-powder method, have been performed. However, cast aluminum/graphite or aluminum/graphene composites have not been widely investigated and the research on this production method mainly focuses on 3D graphite particle reinforcements. In this study, the use of a 2D graphene structure, i.e. graphene nanoplatelets (GNPs), in the production of cast Al/GNP composites is investigated. Graphene nanoplatelets reinforced cast aluminum matrix composites were produced using aluminum alloy as matrix material and different graphene nanoplatelets contents. Specimens were cast into a heated rectangular steel mold, the temperature of which was 100°C. All specimens underwent tensile and bending tests as well as hardness measurements and microstructural investigation. Ultimate Tensile Strength (UTS) was considerably increased, simultaneously with a slight decrease of elongation at break, in the case of 0.1 wt% graphene nanoplatelets addition. Regarding bending performance, a slight increase was observed as well. The flexural behavior for 0.1 wt% graphene nanoplatelets addition was exactly the same with the matrix material. The graphene nanoplatelets content found to affect both the surface and the chemical composition of the interdendritic region. After 0.1 wt%, further increase of the wt% graphene nanoplatelets content lead to formation of aluminum carbides (Al4C3) at the grain boundaries, with a consequent drop on the mechanical performance of the Al/GNPs composite.

Abstract:
Graphene-reinforced aluminium composites have been widely studied due to their excellent mechanical properties. However, only a few studies have reported their dynamic compression properties. The purpose of this study is to investigate the quasi-static and dynamic compression properties of graphene-reinforced aluminium composites. The addition of graphene improved the compressive stress resistance and energy absorption capacity of the aluminium matrix. An aluminium-0.5 wt.% graphene composite exhibited good compressive properties due to the different interfacial wave impedance generated by the additional grain boundaries or Aluminium-Graphene interfaces.

Graphene has been proved to be an excellent enhancer in metal matrix composites. Core-shell structured SiC nanoparticles and graphene nanosheets (GNSs) were fabricated and incorporated into aluminum matrix using ball milling in the current study. Graphite powder was exfoliated into thin GNSs, which are flexible to wrap SiC nanoparticles. The ductile aluminum particles were firstly flattened and then repeatedly welded and fractured into equalized particles during the ball milling of Al alloy-SiC-GNSs composite powder, which were observed using scanning electron microscopy and X-Ray diffraction. SiC-GNSs were embedded and dispersed into the aluminum matrix during the milling process.

Abstract:
The application of Aluminium alloys becomes significant and most wide in the field of aviation industry. Aluminium 6061, because of its pro mechanical characteristics. Graphene is one of the allotropic forms of Carbon which is abundantly available in nature. The high tensile strength and low density of graphene is the added advantage as it is used as a reinforced material with Aluminium 6061. Graphene was found to be a more suitable reinforcing material that improves tribological properties of metal. Composite materials are mixtures of various parent materials resulting in the formation of materials having a mix of varied desired properties like low weight, larger stiffness, higher specific strength etc. The composite materials so obtained invariably have superior properties to their parental ones. So these materials become a really enticing notice for higher strengthened material for industrial sector. This paper primarily focuses on distinctive effects of utilizing Graphene as reinforcement for Al-6061in the view of tribological characteristics. Graphene has outstanding mechanical and physical properties, creating it a perfect reinforcement material for lightweight weight and high strength metal matrix composites (MMC) like Al-6061. Fabrication, being a important step, because it controls the microstructure, that successively determines the properties of the material, was conducted by stir casting. Stir casting additionally helped within the dispersion of Graphene uniformly within the metal matrix composite. To analyze the effect of tribological parameters damage resistance of the metal matrix composite, linear reciprocating tribometer was used.

Abstract:
From the aspect of exploring the alternative lightweight composite material for the aerospace launch vehicle external fuel tank structural components, the current research work studies three different grades of Aluminium alloy reinforced with varying graphene weight percentages that are processed through powder metallurgy (P/M) route. The prepared green compacts composite ingots are subjected to microwave processing (Sintering), hot extruded, and solution treated (T6). The developed Nano-graphene reinforced composite is studied further for the strength–microstructural integrity. The nature of the graphene reinforcement and its chemical existence within the composite is further studied, and it is found that hot extruded solution treated (HEST) composite exhibited low levels of carbide (Al4C3) formations, as composites processed by microwaves. Further, the samples of different grades reinforced with varying graphene percentages are subjected to mechanical characterisation tests such as the tensile test and hardness. It is found that 2 wt% graphene reinforced composites exhibited enhanced yield strength and ultimate tensile strength. Microstructural studies and fracture morphology are studied, and it is proven that composite processed via the microwave method has exhibited good ductile behaviour and promising failure mechanisms at higher load levels.

Abstract:
Hybridization of aluminium matrix composite is with a view to offset the properties deficient in one composite reinforcement. The present investigation involves a comparative study of AA6063 matrix composites with single reinforcement of Al2O3, SiC, graphene respectively and various hybridized proportions of the same reinforcements. Physical (density and %porosity) and mechanical (tensile strength, fracture toughness, %elongation, elastic modulus, etc.) properties of composites developed via solidification processing technique were evaluated. The porosity of all the composites falls below the maximum acceptable limit for cast metal matrix composite. Maximum values for UTS, %elongation and absorbed energy at maximum stress was obtained by hybrid composite with 4wt% Al2O3, SiC and 2wt% graphene, while the composite with the highest single reinforcement of graphene have the highest value for elastic modulus and fracture toughness. Numerical optimization results show that a matrix and hybrid reinforcements contents of AA6063 (91.413wt.%), SiC (3.679wt.%), Al2O3 (0.277wt.%), and graphene (4.632wt.%) respectively, will result in optimal values for the evaluated properties.

Recently, carbonaceous materials, such as graphene, have proven to be promising additives that show considerable improvements in mechanical and tribological properties of aluminium-based composites. In this present investigation, novel aluminium based hybrid composite specimens of various RGO and Al2O3 contents are prepared using powder metallurgy technique. The composite specimens have been tested in wear and microhardness. The results show that the hybrid composite containing 0.3 wt.% RGO-5 wt.% Al2O3 experiences the highest wear resistance with a hardness of about 76 HV among the tested composite specimens.

Abstract:
In this study, the composite of aluminum metal-organic framework MIL-68(Al) and reduced graphene oxide (MA/RG) was synthesized via a one-step solvothermal method, and their performances for pnitrophenol (PNP) adsorption from aqueous solution were systematically investigated. The introduction of reduced graphene oxide (RG) into MIL-68(Al) (MA) significantly changes the morphologies of the MA and increases the surface area. The MA/RG-15% prepared at RG-to-MA mass ratio of 15% shows a PNP uptake rate 64% and 123% higher than MIL-68(Al) and reduced graphene oxide (RG), respectively. The hydrogen bond and pi-pi dispersion were considered to be the major driving force for the spontaneous and endothermic adsorption process for PNP removal. The adsorption kinetics, which was controlled by film-diffusion and intra-particle diffusion, was greatly influenced by solution pH, ionic strength, temperature and initial PNP concentration. The adsorption kinetics and isotherms can be well delineated using pseudo-second-order and Langmuir equations, respectively. The presence of phenol or isomeric nitrophenols in the solution had minimal influence on PNP adsorption by reusable MA/RG composite.

Abstract:
O aumento das preocupações com o meio ambiente tem trazido à indústria de tratamento de superfícies novos desafios quanto ao desenvolvimento de revestimentos com maior desempenho quanto à resistência à corrosão e ao desgaste, observando a redução do impacto ambiental. Neste contexto, o objetivo do presente trabalho é obter um filme compósito à base de silano com incorporação de partículas de óxido de grafeno visando o aumento da resistência à corrosão e ao desgaste da liga de alumínio AA 2024-T3. A liga de alumínio AA 2024-T3 é um material bastante usado na indústria aeronáutica devido às propriedades mecânicas e à baixa densidade. Contudo, essa liga não oferece a resistência à corrosão e ao desgaste exigidos para aplicação na indústria aeronáutica, sendo necessário o emprego de revestimentos protetores. Dentre os revestimentos propostos para essa aplicação os revestimentos híbridos têm sido estudados, e mais recentemente a incorporação de partículas à essa matriz tem sido proposta visando melhorar as propriedades desses filmes. Nesse trabalho os revestimentos compósitos de matriz híbrida com incorporação de óxido de grafeno foram obtidos pelo processo de sol-gel a partir de um sol contendo os precursores alcoóxidos tetraetoxisilano (TEOS) e 3-trimetoxisilil-propil-metacrilato (MAP) com dispersão de partículas de óxido de grafeno em diferentes concentrações (1 g.L-1, 0,5 g.L-1, 0,25 g.L-1 e 0 g.L-1). Os filmes foram obtidos empregando-se o método de dip-coating à temperatura ambiente, com velocidade de retirada de 10 cm.min-1. O óxido de grafeno utilizado foi caracterizado quanto à estrutura utilizando as análises de FTIR, Raman, TGA e microscopia eletrônica de varredura de alta resolução. Para avaliar a estrutura do filme compósito obtido foram utilizadas as análises de FTIR, Raman e TGA. Microscopia eletrônica de varredura de alta resolução foi usada a fim de verificar a uniformidade do filme e avaliar a dispersão das partículas no filme. Os ensaios de polarização potenciodinâmica e impedância eletroquímica foram utilizados para analisar o comportamento referente à corrosão. Avaliou-se também a molhabilidade dos filmes, pelo método da gota séssil. As propriedades mecânicas do filme foram avaliadas empregando-se o ensaio de desgaste pela técnica de esfera sobre plano e teste de adesão. Nas condições estudas, a adição das partículas de óxido de grafeno não alterou a resistência à corrosão, contudo evidenciou-se uma contribuição positiva quanto ao aumento da resistência ao desgaste do filme.
The growing concern with the environment has created new challenges to the surface treatment industry, encouraging the development of coatings with a better performance in regards to the mechanical resistance and corrosion properties, observing the reduction of the environmental impact. In this context, this work aims to make a composite coating with graphene oxide charge to improve the corrosion and wear resistance in aluminum alloy AA 2024-T3. The aluminum alloy AA 2024-T3 is a material used in the aeronautics industry due to its low density and good mechanical proprieties. However, this alloy does not have the corrosion and wear resistance required by the aeronautics industry, requiring the use of protective coatings. Among the protective coatings proposed for this application, the hybrid films have been studied and more recently the incorporation of particles has been proposed to improve the proprieties of this film. In this work the hybrid matrix composite coating with incorporation of graphene oxide was obtained by sol-gel process from a sol containing alkoxide precursors Tetraetoxisilano (TEOS) and 3-(trimetoxisililpropil) metacrylate (MAP) with graphene oxide dispersion in different concentrations (1 g.L-1, 0,5 g.L-1, 0,25 g.L-1 e 0 g.L-1). The films were obtained using the dip-coating method in room temperature with 10 cm.min-1 of removal rate. For the characterization of the graphene oxide structure FTIR, Raman, TGA and scanning electron microscope were used. To measure the structure of composite films proprieties FTIR, Raman and TGA were used. In addition, the scanning electron microscope was used on composite film on aluminum alloy in order to verify the uniformity of film and to assess the behavior of the particles on film. The potentiodynamic polarization and the electrochemical impedance were used to analyze the behavior against corrosion. To measure the wettability contact angles measured by the sessile drop method were used. The film was examined for mechanical proprieties with the ball-on-plate and with the adhesion test. In the studied conditions, the adding of the particles of graphene oxide did not change the corrosion resistance, but it showed a positive contribution to the wear resistance.

Abstract:
The thermo-mechanical response of unidirectional P100 graphite fiber/6061 aluminum matrix composites (vf = 0.47) was investigated at four temperatures: -150°F, +75°F, +250°F and +500°F, using test methods developed at Virginia Tech. Two types of tests, off-axis tension and Iosipescu shear, were used to obtain the desired properties. Good experimental-theoretical correlation was obtained for Exx, vxy and G₁₂. It is shown that E₁₁ is temperature independent, but E₂₂, v₁₂ and G₁₂ generally decrease with increasing temperature. Compared with rather high longitudinal strength, very low transverse strength was obtained for the graphite/aluminum. The poor transverse strength is believed to be due to the low interfacial bond strength in this material. The strength decreases significantly with increasing temperature. The tensile response at various temperatures is greatly affected by the residual stresses caused by the mismatch in the coefficients of thermal expansion of fibers and matrix. The degradation of the aluminum matrix properties at higher temperatures has a deleterious effect on composite properties. The composite has a very low coefficient of thermal expansion in the fiber direction.

Abstract:

A test fixture for combined tension-compression cyclic testing of unidirectional composites was designed and characterized using 606l-O aluminum specimens. The elastoplastic response of graphite/aluminum l5° off-axis and 90° specimens under tension-compression cyclic loading was subsequently investigated at three temperatures, -l50°F, room temperature and 250°F. The test results showed that the tensile response was predominantly elastoplastic, whereas the compressive response could not be characterized exclusively on the basis of the classical plasticity theory. Secondary dissipative mechanisms caused by inherent voids in the materialâ s microstmcture had an apparent influence on the elastoplastic behavior in compression. At different test temperatures, the initial yield stress in tension and compression were translated in the tension direction with increasing temperature. This is believed to be caused by residual stresses induced inieach phase of the composite. The micromechanics model proposed by Aboudi was subsequently employed to correlate the experimental and analytical results at room temperature. A semi-inverse methodology was incorporated to determine the in-situ properties of the constituents. Comparison between the analytical and experimental results showed good agreement for monotonic tensile response. For tension-compression cyclic loading, fairly good correlation was obtained for l5° specimens, but poor for 90° specimens. The major cause of the discrepancy is suggested to be caused by the secondary dissipative mechanisms.

Abstract:
Abstract Aluminium metal matrix composites exhibiting superior mechanical and tribological properties have gained immense interest in recent years. These comosites are finding broad applications in the fields of automotive, aerospace, military and marine. Graphene Nanoplatelets (GNPs), as reinforcement in composites, have become a prime focus because of its exceptional characteristic properties. In the present study, GNPs are dispersed into the aluminium alloy as reinforcements by using stir casting method. To ensure proper dispersion, sintered pellets of aluminium mixed with GNPs are added to the molten metal. The dispersion of the GNPs and the microstructural changes due to the addition of GNPs are observed using Scanning Electron Microscopy (SEM) and elemental mapping. Vickers hardness tester is used to measure hardness of these samples. To compare the tribological properties of Al/GNP composite as well as pure alumimum samples, pin-on-disc experiments are conducted for a specific combination of sliding speed and sliding distance at different loading conditions. The weight loss, wear rate and coefficient of friction are measured and favourable effects of GNPs on tribological properties of Al/GNP composite are discussed. In addition, the wear mechanism has been understood in detail by conducting microstructural studies of the worn surfaces using SEM and Energy Dispersive Spectroscopy. It is observed that the Vickers hardness of the composite increased to a maximum of 25% while coefficient of friction decreased to a minimum of 26% for Al/GNP composite.

Abstract:
Abstract Metal-Matrix Composites (MMC) are being developed for high wear resistance applications. A new MMC, a graphitic aluminum metal matrix composite consisting of an aluminum matrix reinforced with SiC particles and nickel-coated graphite particles, GrA-Ni™, has been developed by INCO Limited. The addition of nickel-coated graphite to SiC particulate reinforced aluminum plays a similar role to flake graphite in grey cast iron. However, like other MMCs, this composite is demanding in terms of requirements for cutting conditions and cutting tool materials. This paper assesses the machining data for this new composite, in regards to tool life, surface finish and cutting forces. The tests included milling, turning, and drilling conducted with carbide and diamond tools. The test results showed that GrA-Ni™ with 10 vol% SiC – 5 vol% Gr, is easier to machine than existing aluminum composites reinforced with SiC particles, such as 20 vol% SiC reinforced aluminum composite.

Abstract:
A composite made of graphene and aluminum is a promising material for many engineering applications due to its lightweight and relatively high strength properties. Unfortunately, the uniform dispersion of the graphene is considered one of the big challenges since the graphene clusters tend to deteriorate the mechanical properties of the composite. In this study, a graphene reinforced Al6061 composite has been investigated. The composites are fabricated by ball milling the graphene flakes and the Al6061 powder, followed by hot compaction in the semi-solid regime of the Al6061. In addition, a graphene reinforced composite with localized reinforced zones within the composite was also investigated The mechanical properties of the composites are measured by conducting a bend test, and microstructural analysis of the composite and fracture surfaces are performed. According to the bending test results, an enhancement in the strength is clearly observed.

Abstract:
The objectives of this research work are to determine the influence of effect of spark electric discharge machine on the recast layer and indeed the strength properties of the AA 6061-Graphene composites. The green compacts were subjected to microwave sintering at 550 °C for 30 minutes. The sintered samples are then hot extruded at 300 °C to flat plates and air cooled later. The extruded samples are subjected to mechanical characterization for density, hardness and tensile strength. Further, spark EDM process is used to machine the extruded samples. The SEDM processed samples with the aluminium alloys 6061-Gr composites compared with the as extruded condition. The hardness studies on the samples are carried out using Rockwell hardness testing machine with B scale as per standards, Tensile strength studies are carried out in Instron Universal Testing Machine with a standard strain rate of 0.75 mm/min. Recast layer of the SEDM samples is studied using HR-SEM and the thickness of the recast layer is recorded. The influence of the recast layer thickness on the tensile strength the extruded composite is studied. The surface roughness and material removal rate (MRR) of the extruded composites after the SEDM process also studied in correlation with the strength properties.

Abstract:
It is necessary to enhance the mechanical properties of adhesives to replace conventional joint methods with adhesive bonding. Epoxy in its pure state often suffers catastrophic damage due to its obvious brittleness and low fracture toughness. In this study, the double cantilever beam (DCB - Mode I) was used to characterize the fracture toughness of graphene/DGEBA-epoxy nanocomposite adhesive in bonded aluminium alloy joints and bonded composite joints. Adhesives based on an epoxy adhesive DGEBA (Bisphenol A diglycidyl ether) reinforced with two percentages (1wt.% and 2wt.%) of graphene nanoplatelets (GNP) were prepared. In this study, one shows that the fracture toughness of adhesive nanocomposites was significantly better than neat epoxy-bonded adhesives. Both types of joints contain graphene resulting in increased fracture toughness. Therefore, the maximum fracture toughness was observed until the GNP reached 1wt.%, and then it began to decrease, but it is still higher than that of the pure adhesive joint. On the other hand, this work aims to determine the influence of interfacial interactions on the behavior of enhanced bonded joints and how graphene nanoplatelets can enhance the rigidity of the interface between the substrate and the adhesive. In addition, a numerical study using ABAQUS was performed and compared with the experiments performed on DCB. For the modeling of the damage in an assembly joint, the Cohesive Zone Model (CZM) was used for the fracture behavior of the adhesive.

Abstract:
Abstract Acousto-ultrasonic (AU) is a nondestructive testing technique for evaluating composites and composite like materials. The name is based on the fact that advantages of the acoustic emission and ultrasonic testing techniques are combined in this NDE technique. In previous research, AU has been used to evaluate carbon/carbon and GFRP composite materials. The work reported in this paper uses Au to examine the adhesive bond strength of lap-jointed graphite/aluminum composite structures. The Stress Wave Factor (SWF), an AU parameter, was used to quantify the strengths of the two types of adhesives used in this research. Also, AU was used to identify delaminations present in the bond area. AU was used to see if the transverse tensile strength of these composites could be determined and to see if this NDE technique was sensitive to progressive damage. The results indicate that AU can be used to effectively identify the bond strength, the transverse tensile strength, and progression of damage in transverse specimens.
