“…A systematic literature review by Hommel et al (2021) served to investigate where AFS has been used or could be used and which advantages arise from the use of AFS. These results were then used to develop a set of motivators for the use of AFS, which will support the designer in evaluating its potential use.…”

“…The characteristic powder metallurgical manufacturing process creates a metallic bond between the face sheets and the core; as this does not require any adhesives, it therefore has a high recycling quality (Seeliger, 2011). Because of its many advantages, such as high bending stiffness at low density, good damping behavior and beneficial mechanical energy absorption, AFS has a wide range of possible applications (Banhart et al, 2019;Hommel et al, 2021;Sviridov, 2011). Components made of AFS can prove particularly Aluminum foam core Aluminum face sheets profitable in mechanical and plant engineering, for example in load-bearing structures within machine tools (Hipke et al, 2007), and in the automotive industry, such as in battery boxes for electric vehicles or crash-relevant components (Banhart et al, 2019).…”

Aluminum foam sandwich (AFS) is an innovative material for lightweight structures due to its various advantages (e.g. low specific mass). Today, many material properties (e.g. strength) are still not well researched, which is why AFS is not yet considered in current material selection processes. Therefore, AFS has rarely been used in the past and its application potential remains unused. This paper presents an approach toward an appropriate method for considering AFS in material selection processes to assist designers in evaluating whether the use of AFS in an application is profitable.

“…Due to this characteristic manufacturing process, no adhesive is necessary, which means AFS has a high recyclability. Thanks to the other advantages of AFS, such as low density, high specific bending stiffness, and good damping properties, this material can be used for a wide range of different applications (Banhart et al, 2019;Drossel et al, 2018;Hommel et al, 2021a). These particularly include crash-relevant components (Banhart et al, 2019), where the high energy absorption capacity of AFS is advantageous, as well as moving components in machine tools (Hohlfeld et al, 2018) and in general transport vehicles (Viehweger and Sviridov, 2015).…”

Aluminum foam sandwich (AFS) is an innovative material for lightweight structures, consisting of an aluminum foam core surrounded by two face sheets of aluminum. The advantages of AFS are a low density combined with a high bending stiffness, good energy absorption properties, and high recyclability, meaning it can be used for many different applications. However, the number of realized series applications with AFS is low caused by a lack of design knowledge, as shown in various studies. In order to address this lack of design knowledge, a design guideline is to be developed. This paper focuses on the development of such a design guideline based on requirements and demands from the industry and presents a structure. In addition, the individual contents of the design guideline are explained in more detail in order to clarify how designers can be supported in the future when designing products with AFS, so that the full potential of this material can be realized. Finally, a survey in an industrial context evaluates the extent to which this design guideline is a useful form of support, in order to check whether its application can improve the design process with AFS.

“…Aluminium foam sandwich panels (AFS) have been evaluated for many applications, such as an Ariane 5 rocket adaptor [18], solar thermal energy generation, cooking equipment, architectural panels, and blast and bullet protection [19]. Hommel et al [20] tried to identify profitable applications for the AFS and developed a set of motivators for the use of the aluminium foam sandwich. A survey revealed that potential users of AFS need design support and recommendations on how to design with these relatively new materials [21].…”

A sandwich structure is a composite material consisting of thin skins encapsulating a cellular core. Such structures have proven to be excellent energy absorbents and are frequently found in various types of protection. Even so, few studies exist in the open literature on the response of the core material itself under extreme loadings such as blast and impact. Since a blast load is usually accompanied by numerous fragments, it is important to understand and be able to predict the ballistic impact resistance of the often highly inhomogeneous cellular core materials in design. In this study, the ballistic impact response of an aluminium foam with a complex cell structure has been investigated both experimentally and numerically. First, an extensive material test program involving compression tests on cubic specimens loaded in the thickness direction of the foam was carried out to reveal the mechanical properties of the material. In addition, several of the specimens were scanned before testing using X-ray Micro Computed Tomography (XRMCT) to map the multi-scale topology and morphology of the material. These data were later analysed to extract density-variation plots in many different material orientations. Second, ballistic impact tests were conducted using a gas gun where rigid spheres were launched towards aluminium foam plates, and the ballistic limit velocity and curve of the foam material were established. Finally, numerical simulations of both the material tests and the ballistic impact tests were carried out using LS-DYNA and different modelling approaches based on the XRMCT data. It will be shown that, independent of the modelling strategy applied, good agreement between the experimental impact tests and the numerical predictions can be obtained. However, XRMCT data are important if the final goal is to numerically optimise and improve the behaviour of inhomogeneous foams with respect to energy absorption, thermal isolation, or similar properties.
