Research on the Applications of Nanotechnology in Automobile Body Panels and Their Advantages

Abstract

This article introduces the combination of nanotechnology and automobile car body panels. The growing demand of electric vehicles(EV) have emphasized the limitations of traditional material, such as limited battery lifecycles, overweight of body panels, and durability concerns. Nanotechnology can vary the physical, mechanical and chemical properties of the material, which brings more possibilities during the manufacture. This article focuses on metal based, carbon based, and polymer nanocomposites applied to EV body structures and paintings. Carbon nanotubes, graphene reinforced materials, and carbon fiber has greatly contributed to the strength-to-weight ratio and modulus, making car panels lighter and increase the driving range. Aluminum and stainless-steel based nanocomposites boost oxidation resistance and hardness. Polymer nanocomposites modified the paintings to increase scratch resistance, surface hardness and stain removability. Companies like BMW, Tesla has already applied such materials in use. While challenges still exist for the industry, the irreplaceable advantages of nanotechnology in optimizing EV body panels have been proven, and it undoubtedly has a bright and promising future in this field.
