Devanathan Recent Innovations in Sciences and Humanities Highlights the State of Art Developments and Innovations Which Impacts Science and Engineering, 2025 In the view of insinuating an enhanced material for binder jetting 3D printing, nano silicon carbide (SiC) particulate is synthesized and studied for its superior properties which is then bonded with polyester for its application in binder jet 3D printing. In order to predict the physical characteristics of the developed SiC particulate for application in binder jet products, physical investigations are carried out that includes tensile, compression, hardness, flexural and impact tests to superscribe the preponderance of this developed material. In the perspective of letting homogeneity of this product and to understand the morphology, Scanning electron microscopy (SEM) analysis, Transmission electron microscopy (TEM) analysis, FTIR, Energy dispersive X-ray analysis (EDAX) and XRD analysis are conducted. This experimental analysis proves that the developed product has good thermal stability by conducting Thermo gravimetric analysis (TGA) test and results proves the thermal degradation occurs in the beginning itself for initial mass change of 9.56% at 390 °C. Also, greater resistance to water absorption of 0.001%. This nano silicon carbide particulate is used to form polyester matrix composite nPMC, which is heat-resistant, lightweight and noteworthy compressive strength.
Optimization of energy absorption and vibration behaviour of TPMS Schwarz P and Schoen Gyroid lattice structures using Taguchi L9 orthogonal array N. Sathishkumar, K.M. Kumar, R. Selvam, A.S.M. Udayakumar Journal of Elastomers and Plastics, 2024 In this study, the optimization of printing parameters in fused deposition modeling (FDM) is addressed, focusing on their impact on energy absorption and vibration behaviour of triply periodic minimal surface (TPMS) lattice structures, specifically Pseudo-periodic-based Schwarz P and Schoen Gyroid designs. The experimental design employs a Taguchi L9 orthogonal array involving layer height (0.15 mm, 0.30 mm, 0.45 mm), build orientation (0°, 45°, 90°), and extruder temperature (190°C, 200°C, 210°C) as inputs. These lattice structures are generated through Math Mod and simulated using Blender, with Autodesk Mesh mixer refining the STL file. The lattice fabrication employs PLA (polylactic acid). Comparative analysis is conducted against a high-density solid structure lacking lattice design. Optimal parameters for Schwarz P lattice are found to be 0.45 mm layer height, 0° build orientation, and 200°C extruder temperature, while for Schoen Gyroid lattice, 0.30 mm layer height, 0° build orientation, and 210°C extruder temperature. Solid structure optimization yields 0.30 mm layer height, 90° build orientation, and 190°C extruder temperature. Solid structures outperform Schwarz-P and Schoen-Gyroid in energy absorption and vibration behaviour, with Schwarz P showing superior properties over Schoen Gyroid.
Multi-attribute optimization of AWJM parameters on hybrid kevlar/SS wire mesh epoxy composites M. Subramanian, R. Selvam, N. Monish, Babu. Vinoth Materials and Manufacturing Processes, 2024 Fiber/metal hybrid composites are perceived as superior materials for applications in machine tools because of their enhanced machinability, lightweight nature, and vibration-damping capabilities. The application of AWJM to hybrid composites introduces challenges, including kerf convergence ratio and surface irregularity issues throughout the machining process. This study is all about the AWJM of a Kevlar fiber/SS wire mesh epoxy composite with silicon carbide filler particles and garnet as the abrasive material. The study aims to investigate the effects of varying machining conditions, such as cutting velocity, abrasive performance rate, and nozzle tip distance, and to determine the most effective machining parameters using TOPSIS technique. To achieve this, a total of 27 different experimental trials were conducted, and two key attributes, namely kerf convergence ratio and surface irregularity, were recorded. This approach empowers all-encompassing evaluation and comparison of diverse machining parameter combinations, thus expediting the selection of the most fitting parameters to attain desired machining outcomes.
Effect of silicon carbide on kerf convergence and irregularity of the surface during abrasive water jet machining of fiber-metal hybrid composites R. Selvam, M. Subramanian, M. Diviya, T. M. Yunus Khan, Rahmath Ulla Baig, Tansir Ahamad, Md. Abul Kalam, Abdul Razak, N. Monish, Anteneh Wogasso Wodajo Scientific Reports, 2023 The traditional way to machine hybrid composites is hard because they tend to break, have a high retraction, have a high service temperature, and have an uneven surface irregularity. For high-strength fiber/metal composite constructions, alternative machining methods have drawn interest as a solution to these problems. Current research focuses on enhancing the Abrasive Water Jet Machining process by optimizing its variables using a composite material of epoxy reinforced with silicon carbide, stainless steel wire mesh, and Kevlar. The variables assessed are the Nozzle-to-substrate gap (S), the Abrasive discharge molding and different percentages of silicon carbide (SiC) filler (0%, 3%, and 6% by weight), three different types of hybrid laminates (H1, H2, and H3) were produced. The response surface method (RSM) was utilized in this learning, specifically on a central composite design, to calculate and optimize machining variables based on the Kerf convergence ratio (Kt) and Surface irregularity (Ra) as responses. According to the results, the traverse feed velocity, Abrasive discharge proportion, and Nozzle-to-substrate gap are the critical factors in determining Surface irregularity and Kerf convergence width (H1 laminate) for a fiber/metal laminate with 0%, 3% and 6% weight fraction. In the case of a 3% weight fraction H2 laminate, the traverse feed velocity was identified as the primary factor affecting the Kerf convergence ratio. In contrast, traverse feed velocity and Nozzle-to-substrate gap had the most significant influence on Surface irregularity. The findings also indicated that S, followed by Abrasive discharge proportion and traverse feed velocity, are the variables that have the most significant influence when cutting 6 wt% SiC filler particle fiber/metal laminate (H3 laminate). For Surface irregularity, the combination of traverse feed velocity and Nozzle-to-substrate gap had the most significant impact. To validate the optimization results, confirmatory tests was conducted, and the findings were very similar to the experimental values, indicating the accuracy and effectiveness of the optimization process. To better understand the manufacturing processes, a scanning electron microscope was used to examine the morphological features of the machined surfaces, such as delamination, fibre breakage, and fibre pull-out.
