“…Besides these, Fe, [23][24][25][26][27][28] Zn, [29][30][31] and Ti [32][33][34] based variations have been produced and reported in the literature. [55][56][57] To decrease this drawback, MMSFs with cheaper filler material, namely expanded perlite [58][59][60][61][62][63][64][65][66][67][68] and pumice [69] were developed. [35] The filler material (or reinforcement in the composite technologist point of view) is usually built up from oxide ceramics or from iron based metals (steels).…”

Metal matrix syntactic foams (MMSFs, often referred as composite metal foams (CMFs)) are lightweight materials with high specific strength. MMSFs are on the borderline between metal matrix composites and metal foams. On one hand MMSFs are composites, because they are filled by hollow particles and the particles may add strength to the material. On the other hand, they are foams, because the hollow particles ensure porosity to the material. Among metallic foams, MMSFs exhibit outstanding specific mechanical properties due to the hollow inclusions that are typically made from ceramics or high strength alloys, therefore they can be applied as structural materials. The goal of this paper is to summarize the available data on the mechanical properties of MMSFs with aluminum matrix in order to give a strong support to the design engineers. Since the foams are most frequently loaded in compression, the main part of this paper is organized around the available standard related to the compressive properties of porous materials and metallic foams. The quasi-static results are complemented by properties measured at higher strain rates. Besides this, some insight into the basic fatigue properties as well as into the toughness of MMSFs is also provided.

“…However, as for the type 2, typically, 45° shear bands and major deep cracks with low elongation are clear evidences and foam samples often divide into two or more discrete sections. Aside from compressive properties, recently, some researchers focus on other loading types like fatigue and notch sensitivity [41], [62][63][64]. Orbulov et al worked on fatigue behavior of different AMSFs and they claimed that matrix ductility and filler diameter strongly affected the fatigue response [65].…”

In recent times, aluminum matrix syntactic foams (AMSFs) have become considerably attractive for many industries such as automotive, aviation, aerospace and composite sector due to their features of low density, good compression strength, perfect energy absorption capacity and good ductility. Since the AMSF includes filler materials providing high porosity, it can be also named as composite foam and can be placed between traditional metal foams and particle reinforced composites. Glass and ceramic hollow spheres, fly ash cenospheres and ceramic porous materials are usually used in the AMSFs, but, lately, different types of fillers being cheaper and stronger have also being investigated. Although many scientific efforts have been made for the last decade to understand mechanical and physical properties of these advanced materials, studies have mainly been performed on relatively small size samples and remained in laboratory. Therefore, there is still room for improvement in terms of fabrication techniques. In this paper, our aims are to scrutinize newest studies about ASMFs, to create new viewpoints and to introduce an alternative bright perspective for probable real applications.

“…Zhao et al [38] investigated the damage evolution and damage mechanism in closed-cell aluminium alloy foam under tension/tension fatigue loading experimentally, while the failure mechanisms of closed-cell aluminium foam under monotonic and cyclic loading was investigated by Amsterdam et al [39]. Fatigue crack propagation in closed-cell aluminium alloy foam was investigated experimentally by Fan et al [40] and Taherishargh et al [41]. In [42], the authors performed an experimental investigation of the low cycle fatigue behaviour of Furthermore, the effect of the structure irregularity, number and the size of the cell were investigated.…”

A review of the fatigue and fracture behaviour of cellular structures with consideration of their fabrication and characterization is presented in this paper. The review is focused on some typical and often used cellular structures, which are divided into three main groups: (1) pre designed regular cellular structures, (2) irregular cellular structures, (3) composites with cellular cores. For each group, the current manufacturing technique is presented for producing the particular cellular structure belonging this group. Furthermore, the state-of-the-art of the fatigue behaviour is explained for the analysed cellular structures. Based on the findings in this review, it can be concluded that cellular structures show a huge potential to become important lightweight structural materials of the future with further development of additive manufacturing technologies, or with introduction of some new, more cost effective manufacturing techniques. However, the knowledge of the fatigue behaviour of these structures is poor, and should be the subject of the further investigations.
