Abstract
A bumper beam is the curved bar across the front of an automobile that protects it from getting dented or scratched during minor accidents Polymeric composite automobile bumper beam material choices. The composites used in vehicle bumper beams need to be selected with care since they have a major job in the distribution and absorption of impact forces during collisions. In recent years, bumper beam applications have seen a rise in the usage of polymeric composites because of their rare connection of mechanical properties, low weight& design flexibility. This introductions goal is to provide a broad overview of the selection process for elements for polymeric composite automobile bumper beams. Research on bumper of an automobile is very important because a vehicles bumper is designed to absorb as much impact as possible, protecting the more important parts of the vehicle. Inthisstudy,theweightedsummethod(WSM)isusedtofindsuitablecompositepolymermaterialsforautomotivebumperbeams. Six different materials are tested in order to choose It is the absolute material for polymer composite bumper beams in transport. The final rank of this paper the Glass fibre reinforced epoxy (M−1) in 1strank, the Carbon fibre reinforced epoxy (M−2) is in 2nd rank, the Carbon fibre reinforced polypropylene (10%) (M−3) is in 6th rank, the Glass fibre reinforced polypropylene (40%) (M−4) is in 3rd rank, the Glass fibre reinforced polyester (30%) (M−5) in 5th rank, the Glass fibre vinyl ester SMC (60%) (M−6) in 4th rank. The final result is done by using the WSM method.
