Abstract: Design and analysis towards application of advance composites in place of the various conventional materials such as steel can give significant weight and performance advantages. The application of light weight composites materials is now finding its way in the automotive industry due to the growing requirement of the lightweight solutions towards EV vehicle and high strength to weight ratio. However, their low mechanical properties have limited their application in automotive structural components. The study presented here is focused on the design and static nonlinear analysis of a bumper beam and advance composites. Different configurations and designs of the bumper beam were considered for a detail comparative study of the stress and deformation levels. The analysis was done in coherence to the Euro NCAP tests and the offset frontal impact analysis was done. The boundary conditions were aligned with the real time impact conditions for proper prediction of the results. Based on stress, deformation, specific strength and weight, the replacing materials for existing steel bumper are considered and the corresponding energy absorption are calculated. Laminated composites such as Glass, Carbon and Hybrid composites are fabricated & compression moulded to derive the material characterization for associated mechanical properties. SEM analysis for the fractured sample was conducted to understand failure mechanism. The study reveals the limitations and benefit of the technology that can replace steel with advance composite materials and achieve significant reduction in weight.
