The main function of a bumper is to protect the car's body in a slight collision, typically at parking speed. The bumper structure on modern automobiles generally consists of a plastic cover over a reinforcement bar made of steel, aluminum, fiberglass composite, or plastic. In most jurisdictions, bumpers are legally required on all vehicles.
New-style bumpers consist of a flexible plastic skin, usually painted the same color as the rest of the vehicle, mounted on shock-absorbing foam (Styrofoam) that is attached to the actual bumper structure. 1  In the majority of cases, it is only the skin that needs replacing, unless the structure itself is damaged.
