Compressive Behaviour of Aluminium Foam Filled Thin-walled Aluminium Tubes

Abstract

Traffic has an outstanding role in our accelerating and dynamically developing world. Road traffic is a constantly developing part of the traffic. Due to its continuous developments automotive industry is developing rapidly. However, due to increasingly stringent environmental regulations, major developments are aimed to reducing vehicle consumption and pollutant emission. Reducing the total weight of the vehicle can significantly reduce pollutant emission. Reducing total weight is relatively easy to achieve with the development of bonding technologies and the use of new advanced materials. However their changes must not reduce the safety factor. These requirements emphasize the use of internal reinforced elements, which can provide the same strength factor with less weight.
Aluminium foam is a modern material which has good mechanical properties and energy-absorbing ability so it can be used as reinforcement material. Its energy-absorbing ability can be used to absorb energy generated by collisions and to reduce the forces that occur. The impact on the body part due to the impact and the force exerted by the chassis practically compresses the security element there. We investigated the compressive behavior of aluminium foam reinforced thin-walled tubes in this article to make conclusions about their usage as impact absorbers.
