Bumpers

Definition

Bumpers are structural components located at the front and rear of vehicles, designed to absorb impact during collisions and protect both the vehicle and its occupants. They play a crucial role in enhancing vehicle safety, minimizing damage in low-speed accidents, and are often integrated with advanced materials to improve performance and aesthetics. Understanding their manufacturing process and material composition is vital for innovations in automotive engineering.

5 Must Know Facts For Your Next Test
