Review Paper : Bumper Beam made of Honeycomb Sandwich Panel

Abstract

Bumper is a energy absorbing protective element which absorb the energy in front collision and protect valuable parts like radiator etc. Bumper is act like protective shield generally made of steel material. As economic point of view and to reduce consumption of fuel manufacturing of light weight vehicle is requirement of current situation. Application of composite material in automobile sector is now day common thing. Aluminum honeycomb sandwich panel is basically material from aerospace industries and known for its high strength to weight ratio. Sandwich structure basically having its properties due to geometry . To determine various properties of sandwich structure conducting experiments is expensive ,so generally FEA is used .However complex geometry is hurdle so there are various theories are available for simplification of model. These theories convert  3D model in to homogenous model .As far as concerning India manufacturing rate of sandwich structure is very less, so generally cost is more. Greatest giant manufacturer is china we can observe their bullet train and metro transport facility construction.Recently in march 2014 largest selling Indian cars are failed in NCap test in 100% frontal crash test. So  requirement of more energy absorbing material with economy consideration is important.
