    High-Performance Aluminum Matrix Composites Reinforced with Graphene Nanoplatelets a Study on Mechanical and Thermal Behaviour

    By Indradeep Kumar, Arigela Sri Harsha, Vijayakumar B, T. Rajesh Kumar, Surrya Prakash DilliBabu, Thiyagesan M, Avinash Kumar, Prashant Sunagar, K. S. Babulal

    Abstract: This study investigates the effect of graphene nanoplatelets (GNPs) on the mechanical and thermal properties of aluminum matrix composites (AMCs) fabricated using the powder metallurgy route. Aluminum alloy Al-6061 powder was reinforced with varying GNP concentrations (0, 0.5, 1, 2, and 3 wt%), followed by uniaxial compaction and sintering. The influence of GNP content on the composite’s structural integrity, strength, and thermal behavior was thoroughly evaluated through tensile testing, hardness …

    Advanced Functional Nanocomposites: Graphene Oxide Integration into Polyvinyl Alcohol Matrix

    By Indradeep Kumar, Nandakumar V, R.Kiruthika, Santhi M George, T. Himaja, M.V. Someswararao, Shankramma S. Kerur, V Saravanan, Velmurugan Paramasivam

    Abstract: This research explores how incorporating graphene oxide (GO) into polyvinyl alcohol (PVA) can improve its mechanical and thermal characteristics, with the goal of creating multifunctional nanocomposites suitable for advanced technological applications. GO was introduced into the PVA matrix at 0.5, 1, and 2 wt% via a scalable solution casting method. The resulting nanocomposites were characterized mechanically, thermally, and spectroscopically. Tensile testing revealed a significant improvement in mechanical performance, with tensile …

    Enhancing Thermal and Mechanical Performance of Polymer-Based Phase Change Materials with Graphite Nanoplatelets: A High-Efficiency Approach for Energy Storage Applications

    By Indradeep Kumar, Sathiyamoorthy Margabandu, M. Chitra, L.Saravanakumar, T. Magesh, Dhiren Patel, S Richard, M Anusuya, Sapthagirivasan.V

    Abstract: This study explores the performance enhancement and characterization of polymer-based phase change material (PCM) composites reinforced with graphite nanoplatelets (GNPs) for thermal management applications. The integration of GNPs significantly improved thermal conductivity, which increased from 0.38 W/m·K in pure PCM to 2.60 W/m·K with 10 wt% GNPs, marking a 580% improvement. Differential Scanning Calorimetry (DSC) analysis revealed a reduction in latent heat capacity from 180 J/g to 150 J/g—approximately 16.7%—attributed …
