ANALYSIS OF MODERN AND PROMISING MATERIALS FOR ELECTRIC CAR MANUFACTURING

Abstract

The article analyzes modern and promising materials for the manufacture of electric vehicles, taking into account their physical, mechanical, economic, and environmental characteristics. The use of the material advantage coefficient K = (σ – ρ) / C is proposed for a quantitative comparison of the efficiency of steels, alloys, and composites. It has been established that the most balanced indicators are found in new-generation steels (AHSS), 6xxx series aluminum alloys, and polymer composites. By 2030, the share of steel is expected to decrease to 25%, while the role of aluminum and composites is expected to grow to 28–30%. The results obtained are consistent with the concepts of light weighting, additive manufacturing, and circular economy, which determine the development of modern electric vehicle manufacturing.
