Evaluation of energy absorption of aluminium tube partially wrapped with glass/epoxy using Taguchi Method

Various kinds of thin-walled tubes made from different materials have been studied by many researchers for energy absorbers in vehicle structures. Most of the studies were based on metallic or fiber reinforced polymer (FRP) tubes. Only a few studies were carried out on hybrid tubes. A hybrid tube...
