This study examines the impact of through-the-thickness tufted natural Woven Pineapple leaf fibres on the tensile and flexural characteristics of sandwich structures. The tufting process seeks to improve the performance of a sandwich structure by ignoring the delamination between the skin and core. Strengthen sandwich structure interlaminations and make them more resistant to damage. This project focuses on creating and implementing an efficient through-the-thickness reinforcing technique based on hand tufting reinforcement. Totally seven specimens were fabricated six tufted and one untufted specimen. Samples that were tufted had three distinct tufting distances (10, 20, and 30 mm, respectively) and two different angle orientations (450,900). An empirical study was developed that comprised tensile and flexural testing of the tufted and untufted sandwich panels formulate of natural pineapple leaf fiber reinforced with Polylactic acid in order to evaluate the impact of tufting on sandwich structure. The outcome displays the fabrication-specific mechanical characteristics of composite laminates. In the tensile mechanical test, the strength of the tufted specimen (450,900) increased by 17% and 34%, respectively, in comparison to the untufted specimen. According to the results of the flexural test, the highest flexural strength for a tufted specimen is between 35% and 67% when compared to an untufted specimen. This indicates that the tufting was successful in enhancing both the in-plane and out-of-plane mechanical properties of composites. Finally, the fracture surface of the tested specimens is examined using scanning electron microscopy (SEM).

In the current research, investigation of natural rubber (NR)/styrene butadiene rubber (SBR) blend reinforced with carbon black (CB)/silica (SiO2) and with and without silane coupling agent (SCA) was analyzed. The total hybrid filler (CB/SiO2) concentration in the composite was fixed at 50 phr. Cure characteristics, mechanical properties and surface morphology were examined. The results revealed that as the SiO2 content increase, the optimum cure time, scorch time, minimum torque, and maximum torque of NR/SBR-CB/SiO2 composites with and without SCA increased. Except for maximum torque, the optimal cure time and minimum torque of NR/SBR-CB/SiO2 composites with SCA were lower than those without SCA. Compared with NR/SBR composites with SCA, addition of 0/50 CB/SiO2 resulted in 53% decrease of tensile strength and 81% increase of elongation at break, superior to that of NR/SBR composites without SCA. The results revealed that as the SiO2 content increase, the optimum cure time, scorch time, minimal torque, and maximum torque of NR/SBR-CB/SiO2 composites with and without SCA increased. Except for maximum torque, the optimal cure time and minimum torque of NR/SBR-CB/SiO2 composites with SCA were lower than those without SCA.

Aluminum alloys are widely used in the production of aerospace, aircraft, and automotive components. The die casting components are subjected to post-processing operations, such as milling and turning operations to get final shape, surface finish, and dimensional tolerances. During machining operations large quantities of material are removed from the cast components in the form of chips to achieve final shape and size. The chips that are produced during machining operations are mixed with oils, lubricants. This article discusses how effectively the aluminum can be recovered from the chips with maximum metal recovery and minimum melting loss without compromising quality and chemical composition. The different types of techniques are employed, and their results are discussed in this paper. Al-Si8Cu3Fe (LM24) alloy is selected for investigation purposes. The recovery techniques, such as with flux, without flux, with different melting furnaces, with different melting temperatures, with or without compacting, are studied.

The main objective of the current research work is to explore the effect of nanosilica particles on the compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). The composite EPDM/SBR with and without silane coupling agent was processed using an open mill mixer. The nanosilica particles are prepared in the laboratory and were used as the reinforcing material in EPDM/SBR rubber composites. The cure characteristics, mechanical properties, hardness, rebound resilience, swelling resistance, abrasion resistance and compression set of the composites are completely analyzed and studied. Nanosilica particles are produced in the laboratory and used as reinforcement material in EPDM/SBR rubber compounds. Fully analyzed and examined are the cure characteristics, mechanical properties, hardness, rebound resilience, swelling resistance, abrasion resistance and compression collection of the composites. It was also evident from the result that with the inclusion of nanosilica particles in the EPDM/SBR rubber composites, the mechanical properties, swelling resistance, hardness, abrasion resistance and compression set properties improved.

The ethylene-propylene-diene monomer/styrene-butadiene rubber (EPDM/SBR)-nanosilica (SiO2) nanocomposite was prepared. The 0–10 parts per hundred rubber (phr) of SiO2 with EPDM/SBR was mixed on a two-roll mill. The effect of nanosilica (0–10 phr), crosslinking system (sulphur, dicumyl peroxide and mixed) and silane coupling agent (bis(triethoxysilylpropyl)-tetrasulphide) on the curing characteristics, mechanical properties, rebound resilience, compression characteristics, abrasion, swelling property and morphological characteristics of the EPDM/SBR-SiO2 nanocomposites was investigated and studied. From the results, it was clear that the mechanical, wear and swelling properties steps-up with increase in the content of nanosilica particles in it. The sulphur cured rubber composite exhibits an overall improved properties as compared with other crosslinking agents such as peroxide and mixed systems. The addition of silane coupling agent (SCA) enhances the properties of the nanocomposites to a greater extent. From the analysis, it was clear that the effect of nanosilica concentration in the rubber composite with SCA was found to be superior compared to nanocomposites without it.

AbstractHighly dense yttria-stabilized zirconia (YSZ) nano-ceramics reinforced with TC-CVD-synthesized multiwall carbon nanotubes (MWCNTs) were fabricated using spark plasma sintering at a temperature of 1350°C, the heating rate of 100 °C/min and pressure of 50MPa with a dwell time of 10 minutes. The identical parameters were utilized for fabricating composites with a varying weight ratio of YSZ and MWNCTs. The samples were characterized for their phase transformation, microstructure and elemental composition using x-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The physical and mechanical properties such as density, porosity, hardness, fracture toughness and wear were also investigated. The increase in the MWCNTs concentration has resulted in the deterioration of the hardness due to CNT agglomerations. The wear resistance of the composites revealed MWNCTs enhanced wear resistance of YSZ nanocomposite by undergoing MWNCTs pull-out and crack branching mechanisms. Further indentation method and single-beam V-notch beam (SEVNB) methods were utilized to study the effect of MWCNTs on the fracture toughness of the nanocomposites. The fracture toughness of YC1 (6.58 ± 0.3 MPa m1/2) was 21% higher than the YSZ (5.21 ± 0.2 MPa m1/2) due to the toughening mechanisms attributable to crack deflection, branching and bridging of MWCNTs.

In this research work, ethylene-propylene-diene monomer (EPDM)/styrene butadiene rubber (SBR) hybrid composites reinforced with nanoclay (NC) and nanosilica (NS) were prepared and investigated. The synergistic effect of NC and NS on the mechanical properties of the EPDM/SBR hybrid composites was examined. Three different crosslinking systems were used, namely: sulphur, dicumyl peroxide and the mixed system consisting of sulphur and peroxide in this research work. The tensile strength, elongation at break, 100% modulus, tear strength, hardness, rebound resilience, abrasion resistance, compression set, swelling resistance and microstructure of the EPDM/SBR hybrid composites were evaluated. The concentration nanosilica along with nanoclay plays a most vital role in the micro-structural, mechanical and other properties of the nanocomposites. From the study, it was clear that the nanocomposites containing 7.5 parts per hundred rubber (phr) of nanoclay and 4 phr of nanosilica shows a maximum mechanical properties along with its abrasion and swelling resistance characteristics. In particular, the sulphur cured EPDM/SBR hybrid composites containing nanoclay and nanosilica results in best mechanical properties and abrasion resistance.

The intention of surface coating is to improve the lifespan of the hazardous liquid storage tank to avoid the catastrophic failure by corrosion or leakage. Water or oxygen present inside the storage tanks tends to permeate through the substrate because of the poor adhesive properties, leading to corrosion, leakage, etc. Recently, polyurea (PU) has been widely used as a surface coating to protect the material under various harsh loads and climatic conditions. However, ultimate variation in the efficiency of PU coating is with respect to various coating process parameters. Herein, the plural spray coating process parameters, namely mixing ratio, temperature, coating pressure, and stand-off distance on the bonding strength of PU coating with steel and aluminium, were optimized. Furthermore, with the help of the Taguchi method, the optimum process parameters and their corresponding levels were identified, and it was found that each response has a different best process parameter. To circumvent this, Grey relational analysis (GRA) was carried out, and it has improved the overall efficiency of both the substrates by nearly 10 %.

Abstract This experimental investigation aims to optimize wire electrical discharge machining (WEDM) process parameters of Al-Al3Fe in-situ composites prepared by reactive stir casting route. Following a robust design lay-out of Taguchi L27 array, WEDM tests have been carried out by varying one material parameter namely, volume percent of reinforcement (VR), and three machining parameters namely, pulse-on time (Ton), servo voltage (Sv) and peak current (Ip); whereas, the material removal rate (MRR) and surface roughness (SR) are considered as output responses. The influences of input parameters on MRR and SR are statistically quantified by ANOVA. Significant process parameters are identified as Ton (69%), Sv (19%) and Ip (7.74%) on MRR; while only Ton (39%) on SR. MRR and SR values are found to be minimum for 20 vol% Al3Fe reinforced composite. Predictive models are generated considering full quadratic response surface equations and validated through several confirmatory tests. Besides, the desirability approach has been adopted for multi-response optimization of MRR and SR; the obtained solutions are affirmed by conducting new tests, and the related error is estimated at less than ±10%. Considering the robustness of the generated models, these models could be used for predicting WEDM performance of in-situ transitional metal tri-aluminides reinforced Al-matrix composites.

ABSTRACT In the modern world, the use of hybrid composite becomes unavoidable. They have their unique and tailor-made properties which makes them suitable for many engineering and industrial applications. But the restriction on the use of composites arises during machining of these composites. Unlike conventional materials, machining of composites is a tedious process due to their anisotropic nature. In the current research work, the prepared high strength hybrid composite is subjected to one of the important machining process say drilling and the process parameters are optimized for the multiple output characteristics namely delamination, torque and thrust force. Taguchi technique aided with grey relational analysis is used for optimization purpose. From the experimental outcome, it is clear that the machining characteristics can be improved at optimum machining conditions. And it is also found that the diameter of the drill has the major effect on the output characteristics.

Abstract Hybrid polymer composites nowadays are increasingly used in many engineering products which are subjected to wear, dynamic mechanical and thermal applications. So in the present study, we have investigated the evaluation of dynamic mechanical, thermal and wear properties of vinyl ester hybrid composite strengthened with Ni-P coated E-glass fiber and Al₂O₃ nanowires as reinforcement at different concentrations. Nickel-Phosphorus is plated over the glass fiber substrate by means of the electroless plating method. The best optimum bath composition was determined after many trials and used for the proper plating process. From the outcome of the result, it is clear that the storage modulus has a trend to increase with increase in the concentration of Ni-P coated glass fiber (GF) and further increases when Al₂O₃ nanowires are used as the reinforcement. The glass transition temperature is also shifted to the higher temperature in the process. From the thermogravimetric analysis, it is clear that the thermal stability of the composite steps up with the addition of Al₂O₃ nanowires as fillers and Ni-P/GF as reinforcement. The wear properties are analyzed and the morphology of the coated and worn-out surfaces are studied by means of scanning electron micrographs and optical microscope images.

Among many machining operations, drilling has become one of the important machining operations performed in polymer composites. The quality of the drilled hole is closely associated with the drilling parameters and conditions. The current work focuses on the optimization of multiple response characteristics during drilling of hybrid glass fiber reinforced polymeric nanocomposites. Taguchi’s L25, orthogonal array is used to conduct the experiments and for optimization of the process parameters. The machining parameters such as spindle speed, feed rate, and drill diameter are optimized for the response which includes delamination, thrust force and torque via grey relational analysis technique. From the grey relational grade analysis, it is clear that the drill diameter is the most influencing factor followed by the feed rate and the spindle speed. The optimized process parameter settings were found as spindle speed of 2700 rpm, the feed rate of 30 mm/min and drill diameter of 4 mm, respectively, for lower delamination, torque and thrust force. Among the various modeling techniques used, ANN is found to be suitable for the process with minimum error percentage of 0.526.

Abstract Optimization is one of the techniques used in manufacturing sectors to arrive for the best optimum conditions, which is an essential need to manufacture quality products at lower cost. Grey relational analysis is one of the efficient solutions to the uncertainty, multi-input and discrete data problems. This method is applied to determine the optimal selection of machining parameters such as peak current (I), pulse duration (Ton), voltage (V), Servo reference voltage (Sv) in Electrical Discharge Machining (EDM) process to identify the variations in two performance characteristics of the work material HCHCr i.e. DIN 17350-1.2080 using copper electrode. Thus machining parameters for EDM were optimized to achieve combined performance characteristics objectives of higher metal removal rate and lower surface roughness value with EDM in magnetic effect and standard EDM on work piece during machining process. The metal removal rate and surface finish is improved with assistance of magnetic field.
