Bumpers in Automobiles

A bumper in an automobile is the plastic component which runs along the length of the vehicle in the front.  It is made of a flexible and tough polymer, fibreglass or a composite material.

The bumper serves to absorbs the energy of low velocity collisions.  The bumper deforms and absorbs the energy of a collision.  Bumpers are designed to regain their original dimension after the energy of the collision has been dissipated.

Besides absorbing energy of collisions, they also serve to protect pedestrians by minimizing the impact.  Some bumpers are designed to guide the people to topple over the vehicle rather than under it.
