Abstract :

This study presents a multi-objective optimization approach to automotive body material selection that seeks to trade-off mechanical performance, cost savings, and environmental sustainability. Utilizing advanced numerical modelling and experimental verification, 45 different materials, including metals, composites, and polymers, were evaluated on the basis of strength-to-weight ratio, hardness-to-cost efficiency, and environmental friendliness. The findings indicate that carbon fiber composite, titanium alloys, and hybrid polymer-metal structures are the optimal materials for light yet strong automotive parts, such that fuel efficiency can be increased by up to 12%. Environmental research indicated that natural fiber composites and aluminum-polymer hybrids significantly reduce CO₂ emissions and energy demands and facilitate global trends toward eco-friendly vehicle manufacturing. Despite budget and scalability problems in integrating high-performance recycled content, the study points to spurring innovation in future lightweight automobile development, focusing on the part that data-driven material selection methods play in reducing carbon footprints and improving vehicle efficiency
