“…Since the original aim of the production of MMSFs was to provide low-weight structural materials with high energy absorbing capacity, the matrix materials of MMSFs are often come from the lightweight alloys such as aluminium (most often, [1][2][3][4][5][6][7][8][9][10][11][12]) and magnesium [13][14][15][16]. However, efforts have been invested into the production of different MMSFs with iron- [17][18][19], titanium- [20][21][22] or zinc [23][24][25][26][27][28] alloys.…”

High performance metal matrix syntactic foams (MMSFs) have been produced by liquid state infiltration of AlSi12 alloy into two loosely packed sets of different nominal diameter (150 μm and 1500 μm) oxide hollow spheres (CHSs) and their mixed packs. The structure of the MMSFs has been studied by X-ray computer tomography and microscopy. The mechanical properties were mapped by compressive tests. The structural investigations showed proper infiltration. In the case of pure small and large CHS filler, the compressive tests revealed high strength levels all over the deformation of the materials up to 50% compressive strain, with the dominance (higher strength values) of the smaller CHSs filled MMSFs. In the case of bimodal CHS filling, the compressive features of the MMSFs have been mixed with two local peaks corresponding to the failure of the smaller and larger CHS filled MMSFs. Rule of mixtures is applicable to estimate the compressive strength.

“…In the publication of Al-Gemeel et al [160], the effect of various combination ratios of PVA and SF fibres and the usage of hollow glass powder admixture on the compressive strength, flexural behaviour and energy absorption of ECC were investigated. In the searches of Nbuchezhiyan et al [161], an endeavour has been made to investigate the mechanical features of HGMs-reinforced die cast magnesium alloy under vacuum die casting process. The morphologies, structures, components and thermal stabilities of the amorphous La 4 Ti 9 O 24 microspheres manufactured by a container less flame spraying method, were investigated by SEM, optical microscope, XRD apparatus, EDX analysis and DSC measurement during the studies of Li et al [162].…”

Glass microspheres are microscopic spheres of glass manufactured for a wide variety of uses in thermal insulation coating, putty, plastic casting polyester, radome, synthetic foam, adhesives, printed circuit board substrate, bowling, fan blades, and caulking materials, emulsion explosives, golf, sealant, pipeline insulation materials, artificial marble, PVC, low density oil drilling, light cement etc. Glass microspheres are usually between 1 and 1000 micrometres in diameter, although the sizes can range from 100 nanometres to 5 millimetres in diameter. Microspheres are spherical particles that can be distinguished into two categories; solid or hollow. This paper presented a general overview of glass microspheres.

“…Hollow glass microspheres (HGM) or other microparticles have been used in syntactic foams or other composite systems as additives to enhance mechanical performance with lowered density. [ 14–16 ] Bilayer foam structures fabricated in a single step (“co‐cured”) from HGM are used as a representative system due to a wide range of densities already available. The co‐cured sample presents a sequential collapse of the constituent layers during compression testing, manifesting as a step‐like progression in the stress–strain profile.…”

Bilayer Glass Foams with Tunable Energy Absorption via Localized Void Clusters

The research in this article entails the design of materials systems and tunable energy absorbing properties respond to a range of energy absorption needs in different impact conditions. Tunable energy absorption of bilayer cellular foams is investigated using hollow glass spheres with different wall thickness and densities. Co‐cured bilayer foams are prepared through sintering of the spheres, and their microstructures and mechanical responses to quasistatic uniaxial compression are investigated. Co‐cured system exploits localized voids density (>50 μm) locally at the interface which is induced via different shrinkage rate of spheres, leveraging tunable energy absorptions. Mechanical testing shows that the voids at the interface lead in the sequential collapse of the layers, resulting in a distinctive two‐step stress–strain profile. For comparison, bilayer samples are fabricated using epoxy. These samples show a different mechanical response from the co‐cured sample by not showing the two‐step stress–strain. The co‐cured samples exhibit 14.8% more specific energy absorption than epoxy bonded samples. The results suggest that co‐cured samples can limit impact stress and achieve a higher energy absorption capacity than epoxy bonded samples. The manufacturing concept and system design expand the capabilities of cellular foams, yielding desired energy absorbing properties in a diverse range of applications.
