Sandwich panels consisting of a highly porous aluminium foam core and aluminium alloy face sheets are manufactured by roll‐bonding aluminium alloy sheets to a densified mixture of metal powders – usually Al‐Si or Al‐Si‐Cu alloys with 6–8% Si and 3–10% Cu – and titanium hydride, and foaming the resulting three‐layer structure by a thermal treatment. We review the various processing steps of aluminium foam sandwich (AFS) and the metallurgical processes during foaming, compare the process to alternative ways to manufacture AFS, e.g. by adhesive bonding, and give an overview of the available literature. Two ways to treat AFS after foaming are presented, namely forging and age‐hardening. Some current and potential applications are described and the market potential of AFS is assessed.

“…Aluminum foam sandwich (AFS) has an extensive application prospect in automotive industry, rail transit and aerospace due to the characteristics of their lightweight, high specific strength and specific stiffness [1][2][3] . Although interfacial bonding strength of AFS prepared by the method of thermal spraying by Maurer M et al [4] is higher than that of adhesive bonding, but the surface quality of AFS is unsatisfactory.…”

Aluminum foam sandwich was prepared by rolling-bonding/powder metallurgical foaming technology, and the effects of rolling on bond strength of face sheet/powders and powder density were studied. Moreover, the foaming agent, TiH 2 , was heat treated and a certain amount of Mg was added into powder in an attempt to understand how the stability and uniformity of foam was improved. The experimental results show that the foaming precursors with ideal quality were obtained by rolling-bonding process. When rolling reduction is 67%, the consistency of powders reach to 99.87%. Throughout consideration of the bonding of face sheet/ core layer powders and deformation characteristic of powders, the optimum rolling reduction is 60%-70%. Cracks and drainage during foaming were inhibited by heat treatment of foaming agent TiH 2 and the addition of a certain amount of Mg. The optimum heat treatment way of TiH 2 is that heat preserving 1 hour at 450 ℃; the amount of adding Mg is 1wt%. ZU Guoyin(祖国胤): Assoc.Prof. ; Ph D;

“…Thus, an aluminum foam sandwich (AFS) structure consisting of an aluminum foam core with dense metallic face sheets is promising for use as a structural component. 1,2) Although an AFS is usually fabricated by bonding an aluminum foam core to dense metallic sheets using an adhesive, 35) the use of an adhesive is limited owing to the difficulty in recycling 4) and environmental problems. 6) As a fabrication process without an adhesive, a powder metallurgical route using metallurgical bonding between aluminum foam and dense sheets has been proposed.…”

Relationship between Porosity and Interface Fracture on Aluminum Foam Sandwich with Dense Steel Face Sheets Fabricated by Friction Stir Processing Route

et al. 2012

An aluminum foam sandwich consisting of an aluminum foam core with two dense metallic face sheets is expected to be used as a lightweight structural component with good energy and vibration absorption properties. In this study, by the friction stir processing route, aluminum foam sandwiches with porosity of approximately 5585% and metallurgical bonding between the aluminum foam and dense steel sheets were successfully fabricated. Moreover, tensile tests were carried out on the fabricated aluminum foam sandwiches. Through the test results, it was shown that, although a brittle intermetallic compound layer exists at the interface, fracture in the aluminum foam part with porosity above 65% occurs and the bonding strength of the interface is higher than the tensile strength of the aluminum foam.
