High-temperature macro-molecular polymer composites for automotive applications: A critical review of sustainable matrices and performance S Kabireal Stephen, S Mohanasundaram, SJ Vijay, DS Ebenezer Jacob Dhas, Rajakumar S Rai Journal of Thermoplastic Composite Materials, 2026 The growing demand for lightweight, thermally stable materials in the automotive industry has accelerated research on high-temperature polymer matrix composites (HT-PMCs) as alternatives to metals in harsh operating environments. This critical review evaluates the current state of advanced HT-PMCs, emphasizing macro-molecular design, processing strategies, automotive applications, and performance limitations. Thermoset systems such as polyimides, bismaleimides, and polybenzoxazines, together with thermoplastic matrices including PEEK, PPS, and recyclable blends, are examined for their mechanical properties, reinforcement compatibility, and thermal stability in the 200–400°C range. Recent advancements in sustainable matrices—particularly bio-based polyimides and recyclable thermoplastics—are highlighted, with comparative analyses of mechanical, thermal, and environmental performance to identify clear trends and research gaps. Case studies in powertrain components, electrification systems, brake assemblies, under-hood structures, and lightweight panels demonstrate weight reductions exceeding 30% alongside improved thermal management. Critical challenges such as moisture absorption, thermal-oxidative aging, and elevated manufacturing costs are discussed, with attention to trade-offs between thermal stability and recyclability. Emerging solutions include hybrid architectures, nanofiller integrations, bio-derived matrices, and self-healing systems, supported by AI-accelerated material discovery. By integrating sustainability with performance, this review provides a comprehensive roadmap for researchers and engineers advancing the next generation of high-temperature polymer composites for automotive applications.
Hybrid PVA composites with basalt fiber and functionalized biocarbon: Mechanical strengthening and EMI shielding efficiency S Mohanasundaram, Dhandapany sendil Kumar, S Manoj Kumar, Indira Priyadarsini, B Sachuthananthan, N Nagabhooshanam, Varaprasad Bhemuni, KK Yaswanth Journal of Thermoplastic Composite Materials, 2025 The research explores the development and performance evaluation of polyvinyl alcohol (PVA) based composites reinforced with basalt fiber and silane treated biocarbon filler. The composites were fabricated using a hand lay-up technique and characterized for mechanical, dielectric, magnetic and electromagnetic interference (EMI) shielding properties. A progressive increase in reinforcement was employed across five composite formulations (P, PF, PFB1, PFB2 and PFB3) with varying biocarbon content. Among the fabricated specimens, PFB2 comprising 50 vol. % basalt fiber and 2 vol. % silane treated biocarbon demonstrated the best overall performance, with a tensile strength of 147 MPa, flexural strength of 163 MPa, impact energy of 5.0 J, shore-D hardness of 90, dielectric permittivity of 4.4, magnetic permeability of 4.30 and EMI shielding effectiveness of 65.92 dB. These enhancements are attributed to improved filler dispersion, optimized interfacial bonding and synergistic reinforcement effects from silane treatment. The results suggest that such hybrid composites are promising candidates for structural applications requiring superior mechanical integrity, dielectric behaviour and EMI shielding efficiency.

Semiconductor Materials for Solar PV Technology and Challenges towards Electrical Engineering M. Siva Ramkumar, R. Felshiya Rajakumari, Nithiyananthan Kannan, R. Premkumar, S. Mohanasundaram, S. Purushotham, D. Ramya, Kavitha Rajan Advances in Materials Science and Engineering, 2022 The contemporary concern in worldwide power scenario and consumption rate is frightening significantly at a marvelous amount of population, and it originates a very high augment in the electrical energy area. The all-embracing attraction and manufacture of fossil energy is the chief reason in the ecological issues. Due to these relic fuels, the ecological resources get exhausted, and it results in climatic change. Due to these negative aspects, every country puts effort to bring the energy efficiency high with the help of renewable energy. Presently, the solar energy donation worldwide decreases. Contrarily, solar energy contribution to the global energy is highly contrary to nonconventional energy resources. But there is a progress in power generation, and it plays a vital role in solar photovoltaic generation. Gallium nitride and silicon carbide power semiconductors will emerge to bring the efficiency high in the photovoltaic technology. In this work, we will converse about how to increase the efficiency by using gallium nitride.
