A systematic review on hybrid composite materials for enhancing fuel efficiency and reducing emissions in automobiles

The growing concern over environmental impacts and the need for sustainable practices have prompted research into innovative materials that can improve vehicle performance while minimizing ecological footprints. Hybrid composite materials combine lightweight, high-strength components such as carbon fiber and polymers with metal alloys to reduce vehicle weight, improve fuel efficiency, and lower emissions while maintaining structural integrity and performance in automobiles. Therefore, this systematic review explores the role of hybrid composite materials in enhancing fuel efficiency and reducing emissions in the automotive sector. The review synthesizes existing literature on various hybrid composites, examining their mechanical properties, weight reduction potential, and overall impact on fuel consumption and emissions. Key findings highlight the advantages of integrating multiple materials to optimize performance characteristics and the challenges associated with manufacturing and recycling these composites. The study concludes with recommendations for future research directions, emphasizing the importance of interdisciplinary approaches to develop effective hybrid materials that meet the evolving demands of the automotive industry.
