• Aluminium foam has been adopted as one of the light filler materials in auto body structural components because of its excellent energy-absorbing ability and lightweight which play a key role in reducing weight and improving safety. This paper combines the porosity of aluminium foam material and the application in car's crashworthy structures to present the energy-absorption behavior and its effect evaluation. First, the paper focuses on the effect of porosity on the energy absorption by experimental study. All the experiments were performed with the specimens subjected to quasi-static axial loadings. As the experimental results, the energy-absorbing properties on porosity are presented, implying that the porosity is a very sensitive factor to energy absorption and the best porosity of aluminium foam in energy-absorption capacity was obtained. A case study on aluminium foam-filled material for automobile front rails was carried out by collision simulations, the improved crashworthiness was verified.
