Abstract
Because of high stiffness and strength to weight ratio, aluminium foam sandwich (AFS) has huge advantage in automotive industries in order to reduce the vehicle’s weight which consequently will reduce the fuel consumption. While reducing the weight, AFS must also maintain high strength and durability compared to other competitive materials used which perform same functionalities. AFS had been proved its suitability for industrial application by previous researchers such as in aerospace, automotive and architecture. However, there is still a gap need to be filled in order to expand the use of the AFS in another application. In this paper, the tensile strength of AFS panel made of from aluminium skin sheets and open-cell aluminium foam core with various thickness is investigated. Design of experiment was developed according to JUMP (JMP) statistical software and experimental work was done using universal testing machine. The stress-strain behavior was analysed. The result shows that the effect of skin to core ratio is significant on the stress-strain behavior.
Highlights
In the past few years, metallic foams have gained their reputations in the industries all around the world
Because of its low-cost manufacturing process and more convenience, aluminium foam tends to be chosen more compared to other type of metallic foam
PM routes on the other hand, used powder metallurgy in order to produce the aluminium foam intended [1]
Summary
In the past few years, metallic foams have gained their reputations in the industries all around the world. When compared to bare aluminium foam, the metal sheets of the AFS that acting as faces allows it bear greater tensile load and reduced the deformation of the core. As the increase of the fuel’s price from time to time, the reductions of automotive weight may be the solutions to the problems of shortage in energy resources that we are facing nowadays. It will benefit us in terms of economic for long term runs. It needs to have a high durability in order to perform well as the substitution material in the constructions of automotive parts
