Analysis of alternate material for bumpers using ULTEM and ABS

Bumpers are safety structures that are hitched to the anterior and posterior end in a vehicle to protectinternal components from impacts and collisions. Internal vehicle components are protected by bumpers by dissipating kinetic energy created by an impact. Bumpers should possess some characteristics such as aerodynamic efficiency, good impact absorption and should be light-weight. Bumpers are meant to dent during the impacts rather than holding its original shape, when the bumper dents it absorbs the impact energy and preventing them being transferred into the passenger compartment of the vehicle. So in order to increase the efficiency and performance of the bumpers, a better material with improved properties, better tensile and flexural properties. In addition to that, all the newly manufactured vehicles are concentrating towards weight reduction, hence these alternate materials (Ultem and ABS) are light in weight hence minimal amount of weight reduction can also be achieved.
