“…There are a variety of porous structures in nature, such as coral, bone, sponge, wood, etc. Inspired by nature, human beings fabricated a series of porous materials [1][2][3][4][5][6][7]. Porous metal has excellent mechanical and physical properties, such as low density, high specific strength, and good sound absorption [8][9][10][11][12][13][14][15][16][17].…”

Closed-cell aluminum foams have many excellent properties, such as low density, high specific strength, great energy absorption, good sound absorption, electromagnetic shielding, heat and flame insulation, etc. As a new kind of material, closed-cell aluminum foams have been used in lightweight structures, traffic collision protections, sound absorption walls, building decorations, and many other places. In this paper, the recent progress of closed-cell aluminum foams, on fabrication techniques, including the melt foaming method, gas injection foaming method, and powder metallurgy foaming method, and on processing techniques, including powder metallurgy foaming process, two-step foaming process, cast foaming process, gas injection foaming process, mold pressing process, and integral foaming process, are summarized. Properties and applications of closed-cell aluminum foams are discussed based on the mechanical properties and physical properties separately. Special focuses are made on the newly developed cast-forming process for complex 3D parts and the improvement of mechanical properties by the development of small pore size foam fabrication and modification of cell wall microstructures.

“…Open-cell metal foam is a porous structure that consists of interconnected pores. Traditionally, it can be produced through liquid metallurgy or powder metallurgy routes, which include melt foaming, gas entrapment method, powder sintering, combustion synthesis and other methods [1]. Those manufacturing methods can influence its physical properties and suitability for use in industries such as automotive, aerospace, electronics, and biomedical engineering [2].…”

3D printing technology has gained popularity among researchers since it can produce complex geometries, such as open-cell foam. The open-cell foam shows potential in a range of applications such as energy absorption, thermal management, filtering, and acoustic damping. However, the feasibility of the applications depends on the material used to construct the 3D printed open-cell foam and its physical properties e.g, pore size and porosity. Therefore, understanding the physical properties is crucial in classifying this new generation of open-cell foams. This study aims to determine the permeability of 3D printed foams using the Forchheimer equation and compared the results with a fractional estimation method to reduce the duration of future experiments. The fractional results were validated through computational fluid dynamics (CFD) simulations. The result shows that the proposed estimation method can be used to determine the permeability of 3D printed foam with a height of 60 mm or larger, and up to six times larger than 5 PPI (pores per inch). However, it is recommended to conduct simulations of large pore size foam using a 3D model to accurately describe the local velocities in the free stream region.

“…

Nowadays, metal foams and composite metal foams are more and more widely researched, [1][2][3][4][5] and metal foam-filled tubes (FFTs) have also become an increasingly researched area amongst metal foams, as these structures are more resistant to various types of loads than metal foams without a sandwich structure or surrounding elements. The properties of cellular structures can be further increased by filling them into dense metallic sections or using hollow cast pieces supported by the foam filling from the inside.

For composite metal foam structures to be used as load‐bearing and energy‐absorbing elements, comprehensive testing should be done. Therefore, an extensive characterization of foam‐filled structures by various load types, such as axial and lateral compression, as well as three‐point bending, is carried out, aiming to differentiate the behavior of various cross‐sectional geometry foam‐filled hollow sections and the application of a tough epoxy adhesive and a ductile polysiloxane adhesive. Applying the epoxy adhesive improves the overall energy absorption by 10 % during axial compression compared to the sum of the foam and empty hollow section. The application of the polysiloxane adhesive over the epoxy one increases the deflection at failure during three‐point bending by an average of 58 %. The deformation and strength during axial compression and three‐point bending are hollow section dominated, while the foam core dominates the deformation and the strength during lateral compression for both produced composite foam‐filled hollow sections with epoxy and polysiloxane adhesive bonding.This article is protected by copyright.
