Due to its high strength, low density, and excellent mechanical properties, the addition of nanocellulose to plastics, resins, and composites used in the manufacture of automotive components, such as bodies and interiors, can reduce vehicle weight, improve fuel efficiency and performance. Nanocellulose, when combined with other materials, can form nanocomposites that enhance the strength, stiffness, and durability of automotive parts. These composites can be applied to body frames, hoods, doors, seats, and other parts, improving the overall structural performance of the automobile. Their flame retardant and high temperature resistance properties can enhance the safety and durability of the automobile. Additionally, the incorporation of nanocellulose can improve the material's performance characteristics, such as increasing its impact resistance, wear resistance, and corrosion resistance, thereby extending the lifespan of automotive components and reducing maintenance costs.
