Energy Absorption Capability of Hybrid Tube Made by Mild Steel and GFRP under Quasi-Static Loading

Article Preview

Abstract:

Hybrid tubes made by metal and composite combine the benefits of the high strength to weight ratio of the fiber/resin composite and the stable, ductile plastic collapse mechanism of the metal, to form a composite tube with high strength and energy absorption capability. The improvement of energy absorption parameters of circular steel tube as crash energy absorber that usually is used in automobile and train structures is studied in this paper. In order to improving energy absorption characteristics, circular steel tube wrapped by glass fiber reinforced polyester with different fiber orientation and various number of layers tested under axial quasi-static loading to achieve the optimum structure.
