Bumper is one of the main parts which are used as protection for passengers from front and near collision. The aim of this study was to analyze and study the comparison between steel and fibre reinforced plastic for use as a car bumper. The existing steel bumper is replaced with fibre reinforced bumper, due to its strength and weight reduction. In this project the design and fabrication of composite bumper made up of glass fibre reinforced plastic is carried out by which weight of the bumper can be reduced. Fabrication of composite bumper is analyzed and carried out by hand lay-up process by using E-Glass, epoxy resin, polyvinyl Alcohol (PVA). Fibre- reinforced bumper is analyzed using impact strength test. Compared to steel bumper, the fibre reinforced has higher factor of safety (FOS) and 80% less in cost. Fibre- reinforced bumper is found to have 64% From the fabrication when compared to steel bumper, it was found that the weight reduction of 53.8% is achieved using composite material. It was also found that fibre reinforced plastic has high strength, high fatigue resistance, it can withstand high creep and is corrosion resistance.
