Surya, and Naresh, K., “Development and experimental evaluation of titanium diboride particulate reinforcements on the Al6061 alloy composites properties”, Advances in Materials and Processing Technologies, pp. 1-17, 2020.[Abstract]


In recent times, industries are focusing to develop newer materials with superior properties compared to the materials available at present. In this regard, the present investigation is aimed at the fabrication and evaluation of the physical, mechanical and tribological properties of Al6061 alloy reinforced with Titanium Diboride particulates. The Al6061-titanium diboride composites were fabricated via liquid metallurgy route. The amount of reinforcement addition in the Al6061 was varied from 0 to 6 wt% in the steps of 2. The physical, mechanical & tribological experiments were conducted on the Al6061 alloy and its titanium diboride composites as per ASTM Standards. As per the obtained results, it can be understood that with the increase in weight percentage of titanium diboride reinforcement, the properties like density, hardness and strength increased with the decreasing elongation. The wear experiments were carried out on pin-on-disc tribometer and results indicate that the fabricated Al6061-TiB2 composites showed higher wear resistance. Out-off all the compositions considered in the current work, the Al6061-6 wt% TiB2 composite material displayed improved properties. The optical, scanning electron, and energy dispersive microscopy images were used to study the composites before and after the casting, fractured and worn-out surfaces.

Aluminum matrix composites are often preferred in automotive, aerospace, and ship building owing to their enhanced properties over conventional engineering aluminum alloys. In this article, the results of the investigations on the mechanical properties and sliding wear behavior of aluminum–tungsten carbide (WC) composites are presented and discussed. Metal matrix composites of Al6061 containing different percentages of WC were prepared by powder metallurgy techniques. All testing was conducted according to ASTM standards. The dry sliding wear tests were conducted at a constant velocity and load varying from 10 to 40 N. The composite density was found to increase with greater filler contents and is further in agreement with the values of theoretical density. The Brinell hardness and ultimate tensile strength of the composites increased with a greater ceramic phase and decreased filler size, with a decrease of percentage elongation. The dry sliding wear of the composites with WC reinforcement displayed the greater resistance to wear.

The present investigation mainly concentrates on work done in order to explore physical, mechanical & tribological characteristics of Al6061 alloy reinforced with nano-sized zirconium dioxide particulates. Four casts of different percentages of reinforcement from 0 to 6 wt% in the steps of 2 are fabricated using liquid metallurgy technique (stir casting). The prepared composites later subjected to various physical, mechanical & wear tests and results were studied. The tests were carried out in accordance with the ASTM standards on the alloy and nano-composites. In the present investigation the physical and mechanical properties like density, hardness and tensile strength increased significantly with the increase in percentage of reinforcement in the matrix alloy, while the percentage elongation found to be decreased. The sliding wear tests were performed by using pin-on-disc the tribometer and results indicated that wear resistance of composites was higher. Off the four compositions, there were improved properties of composites with higher weight percent of reinforcement. Scanning Electron Microscope (SEM) micrographs was used after tensile testing to study fractured surfaces of specimens and wear morphology after wear testing. Overall the investigational outcomes are very interesting and motivates to do further more research.The present investigation mainly concentrates on work done in order to explore physical, mechanical & tribological characteristics of Al6061 alloy reinforced with nano-sized zirconium dioxide particulates.

The present paper focuses on the investigation of physical, mechanical and tribological characteristics of Al6063 alloy reinforced with Silicon Nitride powder. The Al6063-Silicon Nitride Metal Matrix Composites were fabricated by following stir casting method of liquid metallurgy technique. The amount of reinforcement incorporation in matrix material was from 0 to 10 wt% varied in intervals of 2. The obtained composites were used in the investigative studies related to physical, mechanical & tribological experimentations. The tests were performed on the Al6063 alloy and its composites as per in harmony with the ASTM Standards. The test results it can be observed and appreciated that increasing the reinforcement percentage, the characteristics like hardness and density increased monolithically and significantly. The dry sliding wear test is performed using pin on disc configuration tribometer and the results state that the composite has higher wear resistance. Basically the Al6063 is relatively soft and as per dry sliding wear concern at the applications of stringers, upper and lower wings of aircraft, floor breams, seat tracks, fuselage of an aircraft's, the wear resistance plays a crucial role in relative movement at contact surfaces, hence the present work focused on developing Al6063-Silicon Nitride Metal Matrix Composites with enhanced mechanical and tribological properties. Off all the compositions, the composite material having the highest percentage of reinforcement showed better properties. Scanning Electron Microscope, Energy Dispersive Microscopy images were used to study the fabricated composites before and after the wear morphology during wear test. © 2019

Composite materials are better and are used than other conventional structural materials because they offer superior performance, high specific strength and stiffness, excellent fatigue resistance, low weight and design flexibility. These above-mentioned properties have become the winning alliance that impels fibrous composite materials into new arenas. Glass Fiber/Epoxy Polymer Reinforced Plastic composites are widely used over other orthodox engineering materials in the Automobile and Aerospace industry owing to the improved properties. In the present work, an attempt has been made to study the properties of combination of unidirectional E-glass Fibers and carbon reinforced matrix (Bituminous coal tar + Epoxy) with an increase in weight proportions (wt%) of coal tar from 0 wt% till 10 wt%. The properties of cryogenically exposed Glass - Fiber Bituminous carbon coal polymer composites (GBCPC) are studied and compared with that of unexposed. The composites density was found to increase with bituminous coal tar in matrix. The Hardness, Ultimate Tensile Strength and Inter-Laminar Shear Strength of the composites witnessed an increase with greater matrix reinforcement wt% and after cryogenically exposure hardness and ultimate strength have witnessed an increase but Inter-Laminar Shear Strength shows phenomenological behavior, it can be due to micro cracks as well as delamination in the composites due to thermal residual stresses. The sliding wear test was conducted using Taguchi L16 method. The dry sliding wear of the cryogenically exposed specimen displayed higher resistance to wear.

The whole idea is to produce eco-friendly plates from the sheaths of the Areca palm tree leaves. The technology developed for and employed in the project has negated the issues of production challenges that occurred due to humid weather conditions, high cost machines and low quality and fungus prone products. We have ergonomically designed the press machine. The dried sheaths are placed inside the machine using the required die size to manufacture plates and bowls of different sizes. The upper die plate made of aluminium is heated using electricity. Then the sheath is placed on the lower die and will be pressed against the upper die to create plate. In order to remove moisture content, we have designed an indirect forced convection Solar dryer. With integrated cutters in die, a separate cutter mechanism is avoided to prevent reduction of sheath waste. The most distinguished achievement of the project lies in its ability to develop entrepreneurial spirit among the rural unemployed youth, by providing them a dignified livelihood generation activity. Further the current technology will ensure to produce plates at a cost of 1 rupee which is way less than banana leaf. Most of the existing machines are costly in nature and they range from 1.5 lakhs to 3 lakh rupees. Further most of these machines lack a drying chamber. The initiative boosts the growth of palm trees ensuring year round employment and women empowerment leading towards creation of a self-sustained rural economic model.

In this paper we try to obtain the numerical integration formulas to evaluate volume integrals over an ellipsoid by transforming into a 10-noded standard tetrahedral element. We first transform the ellipsoid to a sphere of radius one. A sphere of radius one in the first octant is divided into six tetrahedral elements (with three straight edges and three curved edges) by choosing a point P on the surface of the sphere. Later we consider each curved tetrahedral element to be 10-noded elements and transform them to standard tetrahedral elements (10-noded) with straight edges. Then we evaluate numerical integral values of some integrands by applying these transformations over the ellipsoid using MATHEMATICA-software. The performance of the proposed method with that of the generated meshes over ellipsoid is analyzed using some example problems. We observe that the ellipsoid has been discretized into 48 standard 10-noded tetrahedral elements and the results are converging to the exact integral values with minimum computational time.

This article presents the investigative work carried out to study the relationship between the physical, mechanical and tribological characteristics of aluminum matrix composites reinforced with Titanium dioxide (TiO2). The powder metallurgy route of production was followed to produce the composites (Al6061 containing 3 wt% TiO2). The composites were subjected to sequences of physical, mechanical and tribological investigations. The outputs of the experiments done indicate that the increase in TiO2 fillers increase the density of the composite and the values accepted by the rule of mixtures. The result of mechanical characterisation of Al6061-TiO2 composites was noticed to increase significantly with higher TiO2 content in the matrix, with loss in ductility. The dry sliding wear studies of Al6061-TiO2 composite showed greater wear resistance than Al6061 matrix and the composite containing higher filler content displayed the superior physical, mechanical and tribological characteristics. © 2017, Adcotec Ltd.

The research community has acknowledged the superiority of composite material properties in comparison to conventional materials. Aluminum Metal Matrix Composites (MMCs) sought over other conventional materials in the fields of automotive, sports, aerospace and marine applications due to their admirable improved properties. These materials are of much interest to the researchers from few decades. In this paper, the investigational results of the sliding and mechanical properties of Al6061–WC metal matrix composites are presented. The Al6061 composites containing 0–3 wt% WC were dispersed in the base matrix in steps of 1 and fabricated by powder metallurgy technique. The experimental results revealed that with an increase in WC content there was an increase in the density of the composites and these values are in sync with the theoretical values determined by the rule of mixtures. The tensile strength and hardness of the Al6061–WC composites are directly related to weight percentage of WC and an increase was observed with a decrease in ductility was observed.Wear properties increased, compared to as-cast Al6061 with an increase in WC content in the matrix.

Composite materials are better and are used more than the other metallic materials because of their properties such as light weight, high stiffness and strength, design flexibility and high corrosion and crack resistance. Aluminium Metal Matrix Composites pursued over other orthodox engineering materials in the field of automobile, aerospace and marine applications owing to their excellent improved properties. In the present work, an attempt has been made to enhance the mechanical properties of Aluminium Hybrid Metal Matrix Composites with Titanium Diboride and Graphite reinforcements with increase in weight proportions from 0% to 6%. The composites density was found to increase with higher filler contents and is further in agreement with the values of theoretical density. The Brinell's hardness and ultimate tensile strength of the composites witnessed an increase with greater ceramic phase and decreased filler size at the price of percentage elongation. The microscopic studies also indicate the change in hardness and tensile strength with an increase in grain boundaries and a coarse grain structure. Superior properties were found at 6% weight fractions of Titanium Diboride and Graphite. The sliding wear test was conducted at a constant velocity and different load. The dry sliding wear of the composites with Titanium Diboride and Graphite reinforcements displayed higher resistance to wear.

The exceptional performance of composite materials in comparison with the monolithic materials have been extensively studied by researchers. Among the metal matrix composites Aluminium matrix based composites have displayed superior mechanical properties. The aluminium 6061 alloy has been used in aeronautical and automotive components, but their resistance against the wear is poor. To enhance the wear properties, Aluminium Oxide (Al203) particulates have been used as reinforcements. In the present investigation Back propagation (BP) technique has been adopted for Artificial Neural Network (ANN) modelling. The wear experimentations were carried out on a pin-on-disc wear monitoring apparatus. For conduction of wear tests ASTM G99 was adopted. Experimental design was carried out using Taguchi L27 orthogonal array. The sliding distance, weight percentage of the reinforcement material and applied load have a substantial influence on the height damage due to wear of the Al6061 and Al6061-Al2O3 filled composites. The Al6061 with 6 wt% Al2O3 composite displayed an excellent wear resistance in comparison with other composites investigated. A non-linear relationship between density, applied load, weight percentage of reinforcement, sliding distance and height decrease due to wear has been established using an artificial neural network. A good agreement has been observed between experimental and ANN model predicted results. © 2017 Elsevier Ltd.

G. B. V. Kumar, R. Pramod, D., S. S., and S.G., M., “Investigation of mechanical properties of aluminium reinforced glass fibre polymer composites”, in AIP Conference Proceedings, 2017, vol. 1859.[Abstract]


This paper presents the recent work about reinforcing E-glass into Aluminium foil to attain high strength to weight ratio. Aluminium is corrosion resistant, light in weight and ductile, also when alloyed through other metals deliver the greater strengths as desirable for high-tech applications. The density of pure Aluminium is 2.7 g/cm3. Electrical grade glass formally known as E-glass, is by far the most used fiber in reinforced plastic composites. It is a high strength material with light weight compared to steel and corrosive resistant. The matrix and reinforcement is bonded with a resin, named Araldite Ly556, which has density at 25°C, 1.15-1.20 g/cm3. Thus gives a good binding structure. In the present work, Aluminium, E-Glass and Epoxy are combined to fabricate a laminate by Hand-Lay process. Hand-lay is the oldest and simplest method used for producing reinforced plastic laminates. The fabricated metal matrix composites are tested for their mechanical properties. The metal laminate is found to render high strength, hardness, flexural strength and increased wear resistance. Further theoretical simulations was carried out to validate the experimental results.

Efforts have to be taken to ensure efficient waste management system in shop floors, with minimum utilization of space and energy when it comes to disposing metal chips formed during machining processes. The salvaging of junk metallic chips and the us e of scrap are important for the economic production of a steelworks. For this purpose, we have fabricated a metal chip compaction machine, which can compact the metal chips into small briquettes. The project started with the survey of chips formed in shop floors and the practices involved in waste management. Study was done on the requirements for a better compaction. The heating chamber was designed taking into consideration the temperature required for an easy compaction of the metal chips. The power source for compaction and the pneumatic design for mechanism was done following the appropriate calculations regarding the air pressure provided and thrust required. The processes were tested under different conditions and found effective. The fabrication of the machine has been explained in detail and the results have been discussed. © 2017 Author(s).

While fabricating Hybrid MMC's using stir casting technique several technical challenges exist like achieving a uniform distribution of reinforcement within the matrix during stir casting which affects material behavior. Aluminum (AA 443.0) and SiC + MgO has been chosen as matrix and reinforcement material respectively. Experiments have been conducted by varying weight fraction of SiC + MgO (2.5%, 5% and 7.5%) while keeping all other parameters constant. An increasing trend of hardness and tensile strength with increase in weight percentage of SiC+MgO has been observed. The results also reveal that the wear rate of the test specimen's increase with the increasing load and sliding distance. The coefficient of friction slightly decreased with increasing volume content of reinforcement. © 2017 Elsevier Ltd. All rights reserved.

Glass fibre-reinforced plastics (GFRP) composite materials are extending the application horizons of designers in all branches of engineering. The present work is focused on development and determination of mechanical and dielectric properties of hybrid polymer composites of Nomex and High Silica Glass fabricated through handlay process. Five laminates each were fabricated for four different stacking orders with an average of 55% matrix contents. The polymeric composite was tested for mechanical and dielectric properties. It is found that the hardness was boosted in the laminate with the presence of more layers of High Silica glass fibers, presence of higher number of Nomex contributed for an increase in the compression strength and High Silica glass fibers and Nomex had an equal effect in increasing flexural strength of the composite. The Nomex and E-glass fibers present in the core of the composite covered by High Silica glass on the outer layer of the composite offered very good dielectric strength and surface resistivity for the composite and the absence of E-glass fibers have enhanced the dissipation factor. Further all laminates showed a greater stability towards chemical attack and temperature stability was observed up to 300° C. © 2017 Elsevier Ltd. All rights reserved.

VIT, Vellore, TN, pp. 11376 - 11385, 2018.[Abstract]


The Aluminuim metal matrix composites [MMC’s] have been widely sought over conventional materials for marine, aerospace and automotive applications owing to their excellent wear resistance and mechanical properties. Al7075 alloy though possess high strength and toughness, they exhibit poor resistance against wear and to enhance this property the matrix has been reinforced with ceramic particulates of Al2O3. The MMC was fabricated using vacuum assisted stir casting technique by reinforcing the matrix with Alumina particulates of average 150μm with weight percentage varying from 2%-6%. Wear results in damage of machine components and in order to analyze this complex phenomenon, experimentation was carried out using L27 orthogonal array technique according to ASTM G99 standards. The loss of material in terms of wear-height of the base alloy Al7075 and Al2O3 reinforced composites increased with load applied and sliding distance, similarly trend was observed to decline with an increase of the reinforcement Al2O3 in the matrix material. An Artificial Neural network[ANN] was established for the forecast of tribological properties of the Al7075-Al2O3 composites using Levenberg–Marquardt optimization technique to establish a nonlinear relationship between density, wear height loss, sliding distance and weight percentage of particulate reinforcement. A good agreement has been witnessed between experimental and ANN model results. After ANN prediction confirmation tests were carried out for experimental results for verification.

Machining of metals is the major stage of manufacturing system. This work is mainly concentrated on the vibration and thermal study during cutting process on lathe. Extreme vibration happens in the machining environment because of a dynamic movement between cutting apparatus and work piece. In all the cutting processes, vibrations and temperature impacts are prompted because of the disfigurement of the work piece and cutting apparatus wear, so the motivation behind this present work was to research the impact of the cutting parameters on the temperature at the edge of the cutting apparatus. The temperature has been measured utilizing a test setup with thermocouple and the vibrational characteristics using vibrometer. Finally, the experimental results were simulated using finite element software ANSYS work bench 15. The results and conclusion from this work help to analyze the cutting tool behavior, to get good surface finish and prevent us from the improper selection of the cutting parameter. © 2017 Elsevier Ltd.

People have harvested energy from the wind for quite a long time. Sails for boats, windmills for crushing grain or pumping water are a couple of illustrations. There is recharged intrigue now in energy harvesting from the wind, since it offers a contamination free method for producing power on a huge scale. The framework that fulfils the transformation of wind energy to power is known as a wind turbine. Presently a-days power is turning out to be rare. So in future, the renewable assets will be utilized to produce power. Indeed, even these days, 5% to 10% of the power is produced from wind and solar. In the meantime, every single work of the person is computerized by machines however the power generation is not up to the level. Above being the case, a hybrid wind and solar energy system was developed for the generation of power. The model is a combination of both horizontal axis wind turbine and solar panels where the blades of the wind turbine are being made by PVC pipes and the solar panel tiles are fitted along with the turbine blades. The project describes the modelling of two emerging electricity systems based on renewable energy: photovoltaic and wind power. The powers produced from both the sources were combined together using a Charge controller and then connected to an inverter. Finally, this power was fed to the residential load. The prototype exhibits an assessment of joined solar and wind system for house hold prerequisites, for example, lighting, fan, and so on. Moreover, wind turbine can be operated at lower wind speeds thus increasing the efficiency of the total system. The developed model of wind turbine was worked for the review to fulfill the vitality necessities on the houses. This model was tried alongside photovoltaic boards to check the power yield and the proficiency of the aggregate plan. A comparison between the suggested system and the proposed system proved that the proposed system had many advantages over the conversional system. The performance of the wind turbine was improved during the production process. At the point when the turbine is utilized with photovoltaic boards, the execution was enhanced fundamentally. © 2017 Elsevier Ltd.

In the past few decades, polymer based fiber reinforced composites havebeen the prime materials chosen over the conventional materials in many indus-tries, whereby drilling has been the secondary manufacturing process adopted forstructural integration. Many specific characteristics of composites such as markedanisotropy, structural non-homogeneity, abrasiveness and lack of plastic deformationdetermine the behavior of composites during machining; this has makes it differentthan machining conventional materials in many respects. The principal objective ofthis work is to present a detailed literature review on drilling polymer compositeswith a focus on delamination. Aspects such as delamination mechanisms, fabricationmethods, the type of drilling process adopted by various researchers, cutting parame-ters employed during drilling, mathematical delamination modelling, effect of thrustforce, spindle speed, thermal loads, tool wear, surface roughness, tool geometry andtool materials on delamination and hole quality are summarized. In addition, therole of digital image processing in delamination assessment was also studied. Con-siderable efforts have been made by various researchers to comprehend delaminationmechanisms, and there is still a demand for characterizing delamination with theimplementation of nano-filler materials, the use of blended epoxy resins, reducedwear on drill tools, real-time drilling monitoring, the effect of stack supports and fiberstacking order, higher quality hole production and avoiding de-burring.
