Creep Behavior of Fiber Reinforeced Polymeric Composite: A Review N. Vaithianathan, A. Manikandan, R. Thamizhvel, E. Rajesh Kumar, S. Sudharsan EPJ Web of Conferences, 2026 This work present a review on explores an overview of the flexural creep behavior of fiber reinforced polymeric composites, which are gaining considerable responsiveness due to their superior mechanical properties, lightweight nature, and versatility in various engineering applications. Flexural creep refers to the time dependent deflection or deformation of a composite material under a constant applied load, particularly in bending. The performance of these composites is affected by the type and arrangement of the reinforcement fibers, the matrix material, and the collaboration between the two phases. Fiber reinforced polymeric composites typically exhibit good initial mechanical strength; however, their long-term performance is significantly impacted by creep behavior, which can indication to undesirable deformations over time. Research has presented that the flexural creep resistance of these composites depends on factors such as fiber positioning, fiber mass fraction, and the compatibility between the fibers and polymer matrix. In particular, the inclusion of high strength fibers, such as carbon or glass, generally enhances the creep resistance, as these fibers help distribute the load more effectively. Moreover, the matrix material plays a important role in governing the creep response, as polymers with higher rigidity tend to mitigate excessive bending deformations. Understanding the flexural creep behavior of fiber reinforced polymeric composites is critical for optimizing their process parameter and ensuring their reliability in long term applications, such as in aerospace, automobile parts and construction industries. Continued research is desired to further explore the consequences of various factors on creep performance and to develop strategies for improving the durability and longevity of these advanced materials.
Comparative Analysis of Performance and Emission Characteristics of a CI Engine Fueled with Biodiesel and Pyrolytic Oil Derived from Cottonseed A. Manikandan, R. Thamizhvel, K. Kalaiselvan, S. Jassir Iqbal Archives of Thermodynamics, 2026 The increasing accumulation of biowaste in the environment, hence the need to investigate alternate energy sources has arisen due to the depletion of fossil fuel stocks. Eco-friendly, non-toxic, stable and biodegradable fuels with a high flash point and suitability for combustion are gaining attention. In this study, cottonseed biodiesel and pyrolytic oil were investigated as alternative fuels for compression ignition engines. Transesterification of cottonseed oil with sodium hydroxide as a catalyst and methyl alcohol as a reactant made biodiesel. Pyrolysis, a controlled thermal degradation process that is done in a safe environment, was used to make pyrolytic oil. A compression ignition engine was used to test the extracted biodiesel and pyrolytic oil after they were mixed with diesel in an 8:2 ratio. The performance and emission characteristics of ordinary diesel were compared with those of carbon monoxide, nitrogen oxides, hydrocarbons, smoke emissions, brake specific fuel con-sumption, brake thermal efficiency and other factors. The B20 blend showed 28.5% brake thermal efficiency, 0.32 kg/kWh brake specific fuel consumption, 22% lower CO, 19% lower HC, and 24% reduced smoke emissions than diesel, highlighting improved combustion and reduced emissions despite higher fuel consumption. According to the findings, cottonseed biodiesel is a suitable substitute fuel for compression ignition engines since it emits less CO and NOx.
Production of oil from plastic waste through thermal degradation process Thamizhvel R, Naveen Raj S, Krishna Raj S Turkish Journal of Engineering, 2025 The production of bio-oil from plastic waste through the thermal degradation process is a sustainable and innovative approach that addresses both environmental and waste management challenges. Pyrolysis is one of the thermal degradation processes that involve heating organic materials in the absence of oxygen, leading to the decomposition of complex organic compounds into simpler products, including bio-oil. In this study, healthcare waste, which typically consists of various organic materials such as medical plastics, syringes, bandages, and medical glucose bottles among other disposable items, is considered. Among these, medical glucose bottles are chosen as feedstock for pyrolysis due to their significant contribution to daily waste in the medical field and their negligible environmental and human health concerns. The pyrolysis process involves heating the medical glucose bottles to high temperatures between 400 and 500 °C in a controlled environment. This conversion process results in the production of bio-oil, char, and gases from the medical glucose bottles. The maximum yield rate of medical glucose bottle waste (MGBW) oil at 450°C of heating temperature will be solid (21%), liquid (27%), and gas (43%), with a calorific value of 42.5 MJ/kg, which is comparable to diesel. The bio-oil obtained from this process has several potential applications, such as in furnaces, and it can also be suitable for CI engines as an alternative fuel
Machine Learning Optimisation of CI Engine Characteristics with WSA Algorithm and Prosopis Juliflora Biofuel Sethuraman Narayanan, Vinodraj Subramanian, Thamizhvel Rajkumar, Vaithianathan Nadarajan Archives of Thermodynamics, 2025 Machine learning, a division of artificial intelligence (AI), empowers systems to gain knowledge from information and refine their capabilities over time. It uses algorithms to identify patterns and make prophecies or decisions. Prosopis juliflora is becoming gradually notorious as an optimistic substitute in biofuel inquiry. The mixing of Prosopis juliflora with diesel for use in combustion engines has been the subject of growing study in recent years. However, limited research has explored the impact of Prosopis juliflora on the compression ignition (CI) engine exhaust employing data-driven optimisation highlighting the need for new inquiries to address this shortfall. We aim to explore the cutting-edge and proficient machine learning driven weighted superposition attraction algorithm to optimise the efficiency and exhaust of CI engines powered with Prosopis juliflora biodiesel – diesel blends. Regression modelling is employed to define the relationships between factors such as the blend percentage and brake mean effective pressure (bar), and responses like the brake thermal efficiency (%), brake specific fuel consumption (g/kWh), smoke opacity (%), NOx (g/kWh), CO (g/kWh), and HC (g/kWh). The data-driven weighted superposition attraction algorithm is subsequently employed to determine the best factor levels. Validation of the results demonstrates that the brake thermal efficiency is enhanced, while the other response variables are effectively reduced, showcasing the effectiveness of this methodology.
Empirical and ANN Optimization Study on Lemongrass Oil Blends in CI Engines S. Vinodraj, N. Sethuraman, R. Prabhakaran, R. Thamizhvel, A. Shabeer, et al. Journal of Environmental Nanotechnology, 2025 This research investigates the efficiency and exhaust characteristics of a CI engine operating with a B20 lemongrass oil biodiesel mixture, systematically exploring the intricate interactions between compression ratios (17.5 and 18.5), injection pressures (220-260 bar), and injection timings (22°-26°bTDC. Leveraging an ANN optimization framework, the study aims to comprehensively analyze and define the experimental parameters. Experimental findings reveal that diesel (F0) outperforms lemongrass oil biodiesel (F1) in BTE and Brake specific fuel consumption (BSFC), with Brake Thermal Efficiency ranging from 27.46%–29.5% and BSFC of 0.29–0.32 kg/kWh, compared to biodiesel's 25.7%–28.4% and higher BSFC of 0.34–0.44 kg/kWh. Diesel also produces lower CO (0.4166%–0.4877%) and NOx (230.45–249.23 ppm), while biodiesel emits higher CO (0.45%–0.59%) and NOx (233.56–249.56 ppm). Biodiesel (F1) has lower HC emissions (47.8–51.9 ppm) but higher smoke opacity (53.9%–58.96%) compared to diesel's higher HC (51.9–63.5 ppm) and lower opacity (54.2%–56.23%). Using an ANN model with Bayesian optimization and activation functions (tanh, sigmoid, ReLU), the study found that predicted values closely align with actual values, with minimal deviations for BTE and HC emissions. However, larger deviations are observed for BSFC and NOx, especially at higher values. Improvements are recommended to enhance prediction accuracy for BSFC and NOx.

Revista Materia, 2025 As the demand for energy-efficient building solutions grows, innovative materials such as thermoplastic bricks have emerged as potential alternatives to traditional construction materials. This study investigates the thermal insulation properties of thermoplastic bricks and their suitability for enhancing energy efficiency in modern architecture. Various thermoplastic polymers, including polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC), were analyzed to determine their effectiveness as insulating materials. The research also explores different fabrication techniques, such as injection moulding and extrusion, to understand their impact on the thermal performance of the bricks. Experimental evaluations were conducted using standardized thermal testing methods to measure the heat transfer characteristics of the brick samples. The results demonstrated that PVC bricks, especially those manufactured through injection moulding, exhibited the lowest thermal conductivity, thereby providing superior insulation. The study highlights the importance of material selection and processing methods in optimizing the thermal properties of thermoplastic bricks. In addition to their insulation capabilities, thermoplastic bricks offer environmental and economic benefits. They can be produced from recycled plastics, supporting sustainable building practices and reducing construction costs. This versatility, combined with their lightweight and ease of installation, positions thermoplastic bricks as a viable option for both residential and commercial applications. The findings of this study suggest that thermoplastic bricks can significantly contribute to reducing energy consumption in buildings, aligning with global efforts towards sustainable and energy-efficient construction. Further research is encouraged to explore the long-term performance and broader applications of these innovative building materials.
