An automobile bumper is a structural component, which contributes to vehicle crashworthiness or occupant protection during front or rear collisions. The bumper systems also protect the hood, trunk, fuel, exhaust and cooling system as well as safety related equipments. A brief description of bumper components and a critical review of polymer-based bumper systems with specific methodology are provided. This article advocates proper bumper design and material selection. The authors also discuss bumper components from the standpoint of the materials and their manufacturing processes.
