“…Anisotropy was detected for each specimen, however for purpose of comparison, average values from three directions is listed in Table 2, since anisotropy of properties is a subject of separate study. The results obtained for commercial foam materials are in accordance with data reported in literature for similar structures [8,17,28]. Mechanical properties of all the designed structures were calculated, however due to similarity of structural parameters explained above, only results for LVT materials with strut diameter of 2 mm will be discussed in comparison with commercial foam materials.…”

“…The obtained edge length of these foams was 15 mm. Obtained structural parameters of commercial foam materials are in good agreement with literature data [8,17,27]. One of the most decisive parameters determining Young's modulus of porous materials is porosity, therefore LVT structures with mean strut diameter of 2 mm were chosen as correlated the closest to the reference materials.…”

“…Structural parameters of commercially available foams such as porosity, specific surface, mean strut diameter and mean pore diameter are commonly studied with use of μCT [5][6][7][8][9]. Furthermore Open-Cell Porous Materials could imitate various natural materials where porosity is key parameter for structural characteristic [10,11].…”

Abstract. In the present paper numerical design of mechanical properties of open-cell porous materials is addressed. A detailed knowledge of mechanisms and parameters determining mechanical properties (i.e. Young's Modulus, Poisson's Ratio) of foams is essential for applications such as energy absorbers or lightweight construction materials. The foam structures were designed using procedure based on Laguerre-Voronoi tessellations (LVT) with microcomputed tomography of commercial foams used as reference. Foam morphology was studied on post-processed computed tomography images and the parameters of LVT structures were compared with commercial materials. Subsequently finite element method (FEM) calculations were performed on both types of structures to validate the LVT design algorithm. The results show that the described design procedure can be successfully used for modeling mechanical properties of open-cell foam structures.

“…The matrix material is usually an aluminium alloy (light and low cost), but nowadays high strength iron based matrices are also investigated [2][3][4][5][6][7][8][9][10][11]. As filler material, commercially available mixed-oxide ceramic [12][13][14][15], metallic [12] or SiC [16,17] hollow spheres are frequently applied, however Taherishargh et al have been made efforts for the application of low cost perlite filler as well [18][19][20].…”

Compressive behaviour of aluminium matrix syntactic foams reinforced by iron hollow spheres

HighlightsLow pressure infiltration is suitable to produce MMSFs with hollow iron spheres.The MMSFs showed plastic yielding and long, slowly ascending plateau region.The matrix and the heat treatment strongly influence the properties of the MMSFs.The full-scale FEM model gives excellent agreement compared to the measured values. Highlights (for review) *Manuscript Click here to view linked References AbstractAluminium alloy syntactic foams reinforced with iron hollow spheres were produced by low pressure, liquid phase inert gas infiltration technique. Four Al alloys (Al99.5, AlSi12, AlMgSi1 and AlCu5) and Globomet grade iron hollow spheres were used as matrix and reinforcing material, respectively. The produced composite blocks were characterised according to the ruling standard for compression of cellular materials in order to ensure full comparability. The compressive test results showed plastic yielding and a long, slowly ascending plateau region that ensures large energy absorption capability. The proper selection of the matrix material and the applied heat treatment allows for a wide range of tailoring of the mechanical properties. For design purposes, the full-scale finite element method (FEM) model of the investigated foams was created and tested on Al99.5 matrix foams. The FEM results showed very good agreement with the measured values (typically within 5% in the characteristic properties and within 10% for the whole compression curve).

“…Rabiei et al [8][9][10] developed CMFs with high energy absorbing capacity and revealed that the high strain rate and the quasi-static strain rate tests can overlap each other. Fiedler and Taherishargh et al [11][12][13][14][15] produced low density and low cost syntactic foams, by the combination of Al alloys and expanded perlite. The authors proved the applicability of these set of foams by numerous versatile investigations.…”

Hybrid syntactic foams with AlSi12 aluminum matrix were produced by pressure infiltration. The volume ratio of iron and ceramic hollow sphere reinforcement (in the same size range) was varied and hybrid syntactic foams were also produced with bimodal size ceramic reinforcement. 2Previously a very detailed analysis of the mechanical properties of the composites was made with quasi-static compression tests and their tribological properties were investigated by pin-on-disc method in dry and lubricated conditions. The present article establishes and clarifies the correlations between mechanical and tribological properties. The coefficient of friction, height loss of the specimens and specific wear showed good correlation to different mechanical parameters e.g. density, structural stiffness and yield strength.The established trends and correlations between mechanical and tribological behavior enables a better understanding for materials design and selection for further applications for mechanically loaded sliding machine parts.
