  • Investigation on geometric, dimensional accuracy and surface roughness for 3D printed PLA via fused deposition modelling (FDM) process
    N. Jayakumar, G. Senthilkumar, M. Kumar
    Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2026
    Fused deposition modeling (FDM) is an advanced additive manufacturing technique known for its precision and repeatability, extensively applied in producing automotive and industrial components. This study employs the Taguchi L 9 orthogonal array (OA) approach to optimize process parameters for minimizing dimensional inaccuracies, geometric deviations, and surface roughness (Ra) in polylactic acid (PLA) specimens fabricated as per ASTM D638 Type V standards. Four critical printing parameters: extrusion temperature (ET), infill pattern (Ip), print rate (Rp), and layer height (LH) are investigated, focusing on specimen thickness (Ts), width of the grip section (Wgs), overall length (OL), circularity (Circ), cylindricity (Cyl), surface roughness (Ra), and waviness (Wa). Signal-to-noise (S/N) ratio analysis identified optimal parameter combinations, revealing that Ip, ET, and Rp significantly influence circularity by 39.24%, 37.34%, and 15.19%, respectively. One of the important factors that affect the degree of inaccuracy in cylindricity is the Ip. Gyroid pattern generated the least amount of inaccuracy out of all the patterns that were tested. Layer height (LH) at 0.1 mm was the most critical factor affecting Ra and Wa, while an extrusion temperature of 215°C predominantly influenced Ts. The Ip has the most affected the grip section width. In contrast to expectation, the triangle Ip achieved the minimum width error that was 0.3384%. The Rp of 40 mm/s has the highest impact on the OL deviations. Out of all the other patterns, the Tri-Hexagon (Ip) has made the least contribution to the OL deviations. Rp exhibited a lower contribution to Ra (2.35%) and Wa (12.45%). The results demonstrate the effectiveness of the Taguchi approach in identifying optimal process setups for enhancing the precision, geometric accuracy, and surface quality of 3D-printed specimens.
  • Development and Characterization of Aerospace Grade AISI 440C and Cronidur-30 Alloy Powders for Additive Manufacturing Applications
    Malaysian Journal of Chemistry, 2025
    The role of Additive Manufacturing (AM) in high-end engineering industries is expanding rapidly with metal AM becoming a crucial choice, particularly in the aerospace sector.The demand for high-performance, corrosion-resistant metal alloys continues to grow.In line with this, the present study focuses on the development and characterization of aerospace-grade stainless steel alloys (AISI 440C and Cronidur-30), for AM applications, especially in bimetal components.The alloy powders are produced using the gas atomization process with nitrogen inert gas atmosphere and evaluated for their chemical composition, particle size, flowability, apparent density and morphology to ensure their suitability for AM techniques such as Direct Energy Deposition (DED).The chemical composition and microstructure analysis of developed alloy powders are carried out through Inductive Coupled Plasma -Optical Emission Spectroscopy (ICP-OES) and Field Emission Scanning Electron Microscopy (FESEM), respectively.

  • Investigation of fused deposition modeling parameters on mechanical properties and characterization of ABS/carbon fiber composites
    Krishnan Ravi Kumar, Nisha Soms, Murugesan Kumar
    Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2024
    The effect of parameters of acrylonitrile butadiene styrene composites reinforced with carbon fabricated by fused deposition modeling was studied in this work. Parameters like infill density, raster angle, layer thickness, and printing parameters are varied and their influence on mechanical properties was analyzed experimentally. Experiments were planned by the design of experiments technique and mathematical equations were generated to analyze the impact of these parameters. ANOVA is involved to ensure the validity of the mathematical equations. The mechanism of the fractured samples was studied using scanning electron microscopy. The tensile strength of ABS/carbon fiber composites ranges from 21.74 to 28.09 N/mm2, while the flexural strength ranges from 2.62 to 3.14 N/mm2 and the impact strength ranges from 3.66 to 5.19 kJ/m2. The fracture of composites is characterized by cavities, infill gaps, bonding, dimples, tearing debonding of fiber, crack, delamination, shearing, crack, and fiber protrusion. The nature of failure varied from ductile to brittle depending upon the change in process parameters.
  • Experimental investigation on mechanical and tribological analysis of pineapple leaf (Ananas comosus) and sisal (Agave sisalana) fibers reinforced hybrid epoxy composites
    Ponnusamy Natarajan, Manoharan Mohanraj, Murugesan Kumar, Selvaraj Sathish
    International Polymer Processing, 2024
    In many industrial applications, natural-fiber-reinforced polymer (NFRP) composites are emerging as a strong substitute for composites based on synthetic fibers. The goal of this study was to examine the mechanical and tribological characteristics, including tensile, flexural, impact, wear, hardness, and water absorption, of hybrid epoxy composites reinforced with pineapple leaf and sisal fibers at various weight fractions. First, 5 % sodium hydroxide was used to treat the pineapple leaf and sisal fibers. With a composition of 0, 10, 15, 20, and 30 wt% of pineapple leaf and sisal fibers to the epoxy resin and its hardener mixture, which had a constant weight ratio of 70 %, hybrid composites were fabricated using the compression moulding process. To create a hybrid epoxy composite reinforced with pineapple and sisal fiber, epoxy resin was used as the binder. Different types of testing were performed on the hybrid composites following ASTM standards. The outcomes were contrasted with composites made from mono-pineapple and sisal fiber composites. In comparison to other composite samples, the 15:15 composite sample exhibited the best mechanical and tribological qualities, including the highest tensile strength, impact resistance, flexural strength, hardness, water absorption resistance, and wear resistance. Using a scanning electron microscope (SEM), the fiber/matrix adhesion was investigated. The 15:15 composite sample exhibits primarily mechanical and tribological properties, making the resultant composite material simpler to use in structural and automotive applications.
  • Corrosion Studies on Al6061 Alloy Based Hybrid Metal Matrix Composites
    R Naveen, M. Kishore Kumar, A. Swarnalatha, R. Ezhilarasu, M.S. Prasath, et al.
    International Journal of Vehicle Structures and Systems, 2023
    Composite materials have gained widespread use in various industries, including aerospace, architecture, automotive, energy, infrastructure, marine and military, owing to their favourable combination of lightweight properties and robust mechanical characteristics. Their corrosion resistance to harsh environments, such as saltwater, acids, and alkaline solutions, further enhances their applicability. This study focuses on investigating the corrosion properties of Aluminium 6061 alloy reinforced with red mud particles. Aluminium 6061 matrix and red mud-reinforced composites are commercially available and widely utilized. Red mud, a by-product of aluminium ore refining, comprises a mixture of iron oxides, silicon, zirconium, titanium, and vanadium. In this research, red mud was employed to reinforce Al6061/alumina/graphite hybrid metal matrix composites, fabricated through the stir casting method with red mud content percentages of 3% and 7%. Cylindrical specimens were meticulously manufactured and machined to ensure uniformity. Subsequently, these specimens were subjected to immersion in concentrated hydrochloric acid for a duration of 96 hours, with periodic observations at 24-hour intervals. The weight of the specimens was recorded after each immersion, followed by drying in an oven for 15 minutes. Corrosion rates were calculated using established corrosion rate formulas. The results demonstrate that an increased percentage of red mud particles in the composites enhances their corrosion resistance compared to the base alloy. The corrosion rate of the alloy exceeded that of the composites. Consequently, this research suggests the practical utility of these composite materials in environments where corrosion resistance is paramount, advocating for the preference of composites over pure alloys.

    M Kumar, K. RaviKumar, P Arunkumar, A Dhanabal
    Mechanical Properties and Characterization of Additively Manufactured Materials, 2023
    Metal Additive Manufacturing (MAM) is a contemporary manufacturing process that has importance in producing automotive, aerospace, and medical implant products. It has become inevitable nowadays because of its rapid and simple additive manufacturing technique. In relation to this, Direct Metal Laser Sintering (DMLS) is getting commercially popularized to producing almost all metal 3D products. The present work investigates the mechanical and tribological behaviors of DMLSed AlSi10Mg alloy and the same is being compared with as-cast AlSi10Mg alloy. The mechanical study is conducted to find its hardness and tensile strength, and the tribological tests are also carried out on pin-on-disc apparatus as per G99-05 ASTM standard to investigate its friction and wear behavior. The mechanical test results indicate the DMLSed AlSi10Mg alloy showed 9.25% higher hardness and 76.47% higher tensile strength than as-cast AlSi10Mg alloy. Fractography analysis is implemented to predict the cause and type of failure, and it is found as a mixture of more of ductile and to some extent brittle failure. The tribological test results reveal that at 20 N applied load, 4.18 m/s sliding velocity, and 1,600 m sliding distance the specimen offers minimum specific wear rate and at 40 N applied load, 2.06 m/s sliding velocity, and 2,400 m sliding distance the specimen offers minimum coefficient of friction. Field Emission Scanning Electron Microscopic (FESEM) analysis is being done to identify the wear mechanisms of the specimens.
  • Enhancing UV resistance of TiO2 reinforced Kevlar 29 fiber using Sol-Gel & Low-temperature Hydrothermal Processes
    Naveen R, Kumar M
    Polymer Plastics Technology and Materials, 2023
    Mechanical properties of Kevlar fibers are significantly affected by their chemical structure when they are subjected to ultraviolet (UV) environment owing to photo degradation effect. In this work, Kevlar fibers are modified by means of impregnating with the titanium dioxide (TiO2) using low temperature hydrothermal process and dip coating methods. Ultraviolet–visible absorption spectrum confirms that hydrothermal treated Kevlar fibers exhibited outstanding UV resistance among others. The UV durability of the TiO2 modified Kevlar fiber is carried out using accelerated photoageing method up to 180 hours. Results of the tensile test showed that the best tensile strength was demonstrated by the modified fiber.

    Automobile bumper is an essential component that is commonly used to absorb the impact load during vehicle collisions, in fact it saves lives at such occurrences.In order to withstand the impact load, and the bumper deforms itself during collision and protects the passengers by havingthe proper cross section and the material selection. In this way, the study explores the mechanical characterization of fabricated composite and its structural analysis. Impact conditions have to be studied for improving the mechanical properties of the bumper during collision. The material chosen for analysis is jute and Glass fiber reinforced hybrid epoxy composite, considering its light weight and strength characteristics. Composites with two different fibre orientations (45°/90°) are fabricated using Hydraulic Compression Moulding technique. From experimental observations of jute and glass fiber reinforced hybrid composites, the orientation has significant effect on the structural and mechanical properties. The results are validated using the simulation of a bumper by impact modelling using CATIA software and impact analysis is carried out using ANSYS.
