IMPLEMENTATION OF CIRCULAR DISCONTINUITIES IN CFRP BUMPER BEAM FOR MATERIAL SAVING: A CASE STUDY

An automotive bumper system consists of an energy absorber, fascia and beam. Among them, the beam is main component contributing to overall weight vehicle. The absorbs kinetic during accidental collision by deflection in low speed impact deformation high impact. Carbon Fibre Reinforced Plastic (CFRP), being extremely strong lightweight composite, a good candidate for material. Earlier used performance cars CFRP nowadays promoted be passenger also. reinforcement vital part which ensures safety needs validated through Finite Element Analysis (FEA). Therefore, double hat impacted with cylindrical impactor analyzed Abaqus. In this paper after reduction putting circular holes material saving. Further effect on cost production calculated. Above all, saving reduces carbon footprint.
