Green Composites for Future Applications: Investigating the Influence of CSP and GGBS on the Mechanical Properties of Bamboo-Jute-Sisal Natural Fiber Reinforced Hybrid Composites H. Amitkumar, G. Mallesh Tribology in Industry, 2025 In recent years, natural fiber reinforced composites (NFRCs) have gained significant attention due to their potential to replace synthetic fibers in various applications. This research focuses on developing green composite materials by combining sisal, jute, and bamboo natural fibers with epoxy resin filled with Coconut Shell Powder (CSP) and Ground Granulated Blast Furnace Slag (GGBS). The composites were fabricated using hand layup and bag molding processes with varying fiber volume fractions of 5%, 10%, and 15%. The results showed that GGBS-filled composites exhibited superior tensile strength, flexural strength, and impact strength, with average tensile strength enhancements of 18.3% (Sisal), 19.9% (Jute), 15.3% (Bamboo), and 10.7% (Hybrid fibers). Additionally, GGBS-filled composites displayed higher Shore D hardness, with Bamboo-GGBS exhibiting a 14.45% higher hardness than Bamboo-CSP. Furthermore, water and oil absorption percentages were reduced by 24.5% (water) and 32.1% (oil) for Sisal, 22.1% (water) and 29.5% (oil) for Jute, 26.3% (water) and 34.1% (oil) for Bamboo, and 23.2% (water) and 30.5% (oil) for Hybrid. EDAX and SEM analyses confirmed the composition and microstructure of the developed NFRCs, revealing strong interfacial bonding, uniform filler distribution, and distinct energy levels of constituents. Overall, these NFRCs, made from Sisal, Jute, and bamboo fibers filled with CSP and GGBS, offer a durable and sustainable solution for various industries, including automotive, aerospace, medical devices, renewable energy, and construction.
Optimizing Bioceramic Composites for Hip Joint Replacements using SPS Method: Investigating the Effects of Titanium Diboride (TiB₂) on Tribological Properties Pavankumar Ravikumar, Goud Mallesh, S. Suresh Kumar, H. S. Manjunatha Tribology in Industry, 2025 This study investigates the fabrication, characterization, and tribological behavior of bioceramic composites specifically engineered for hip joint replacements. Utilizing the Spark Plasma Sintering (SPS) process, advanced ceramic composites were developed, comprising alumina (Al2O3), silicon carbide (SiC), magnesium oxide (MgO), and titanium diboride (TiB2) integrated with an Al6061 base. The objective was to enhance mechanical strength, wear resistance, and biocompatibility for long-term orthopedic applications. Material characterization was performed using Energy Dispersive X-ray Spectroscopy (EDS) and X-ray Diffraction (XRD) techniques, confirming the presence of reinforcing phases and crystalline structures. Wear tests were conducted using a pin-on-disk apparatus, and wear losses were systematically evaluated using a Design of Experiments (DOE) approach with an L27 orthogonal array. Statistical analysis using Minitab software revealed significant differences in tribological performance among composites with varying TiB2 concentrations. Notably, the weight percentage of reinforcement was identified as the most influential factor on wear loss (p-value = 0.000), with higher TiB2 percentages correlating with improved mechanical performance. The optimal composition—5% alumina, 5% SiC, 2% MgO, and 9% TiB2 combined with Al6061—demonstrated enhanced toughness and fracture resistance while addressing the fragility commonly associated with ceramic materials. The model fit was confirmed by an R-squared value of 89.21%, indicating strong predictive capability. SEM analysis post-wear testing highlighted reduced wear tracks in TiB2-reinforced samples. These findings suggest that bioceramic composites exhibit durability against wear, friction, and fracture resistance, which are critical for the long-term effectiveness of hip implants. The study provides a foundation for further investigations into advanced mechanical testing, biocompatibility assessments, and clinical relevance to ensure suitability for orthopedic applications.
Delamination Behavior of Dyneema Composite Laminate due to High Velocity Impact using LSDYNA M. L. Puneeth, G. Mallesh, H. S. Manjunatha Journal of Mines Metals and Fuels, 2023 Failure of composite not only includes tensile or compression failure of fiber matrix, but also the delamination between plies. The current study investigates a methodology for the Ply-Delamination of Dyneema material due Ballistics impact using LSDYNA. A new methodology was implemented in order to effectively capture the ply delamination and the damage caused due to the impact for different velocities. Numerical results obtained were correlated with previous existing simulation results.
Microstructure-based Finite Element Analysis of Composites G. Mallesh, H. S. Manjunatha, R. Pavankumar Journal of Mines Metals and Fuels, 2023 Synthesized Al6061-TiB2 composite material by varying wt.% of TiB2 through In-situ process by adding 1.5% Mg to evaluate mechanical properties. It is noticed that the tensile, impact strength and hardness of the composites increases with increase in wt.% of TiB2 with reduces in ductility. Microstructure analyses were conducted through SEM to observe the distribution, presence and formation TiB2 particles and found that particles were homogeneously distributed and EDX analysis confirms the presence of TiB2. Later, SEM images are converted into 2-D models using Matlab, FE analysis was conducted using ANSYS software to evaluate the stress at the matrix and reinforcement interface. The information revealed from this study is useful in design and selection of Al 6061-TiB2 AMCs for various applications.
Finite Element Analyses of Non-Standard Spur Gears P. Srinivasa, C. Shashishekar, G. Mallesh Journal of Mines Metals and Fuels, 2023 Gears are the mechanical components and are predominate as the most effective means of power transmission in mining equipment which encompasses a wide range of machinery used in the extraction of minerals and resources from the earth. Currently, gears in c equipment are prone to a different types of failures when they are subjected to impact, shock and fatigue loads. It is noticed from the literature that 34.4% of the failures are due to poor lubrication, 19.6% due to impurity, 17.7% due to fixing errors, 6.9% are due to excess load and 2.8% failures are due to handling errors. Further, more than 1,500 gear failures were examined throughout the investigation, and it was observed that tooth bending fatigue is the common mode, leading to tooth fracture at the root owing to bending stress. Bending stress developed at the tooth root can be minimized by modifying addendum of mating gears or the involute geometry. An additional alteration that is rarely used is to make the gear asymmetric or nonstandard. Therefore, in this research work attempts are made to generate non-standard spur gear tooth profile by varying pressure angle and profile shift using Matlab to estimate bending stress using FE software ANSYS. Bending stress calculated using the Lewis equation and FE analysis were compared to validate the FE procedure. It is noticed that bending stress was reduced to 42.14% by increasing the pressure angle from 200 to 400 without altering other gear parameters. Hence, the possibility of tooth break can be minimized with the use of non-standard spur gears.
