Electrical vehicle energy consumption is often reduced by redesigning individual car parts to avoid compromising crashworthiness. By comparing the metallic and, as a result, composite models, the most efficient configuration of an electric vehicle is revealed. Previous research on automotive body materials has looked at both composite and aluminium options. Still, steel has consistently proven to be the most cost-effective option at the assembly volumes used in the vast majority of automobile models. Meanwhile, savings of weight is achieved using the carbon weave fabric composite compared to its predecessor fabricated from fibre reinforced plastics (GFRP). These findings come when they are significant, given the many implications of a polymer composite body for vehicle light- weighting and improved fuel efficiency. Testing and analyzing aluminium material were carried out if it can withstand damage compared to foam and iron. Lightweight composites are widely employed in various marine, transportation, and aerospace applications due to their high strength. In mass transit, replacing metallic parts with reinforced composites reduces weight, improves fuel efficiency, and lowers maintenance costs without sacrificing performance. Throughout this project, we will examine and evaluate various materials to determine the best material for use as an impact attenuator.
