“…The coated SFs compressive modulus was enhanced by 45% compared to the uncoated epoxy SFs. Similar findings have been reported in the works of many researchers [46,47]. Thus implies that the mechanical properties of SFs had obvious enhancement by adding external surface coatings to the microspheres and the matrix.…”

“…The microsphere crushing strength impacts the compressive strength of foam. However, have less contribution when in the deformation was in flexural mode, [19,[45][46][47]. For example, in a resin rich matrix, the excess number of epoxy resin monomer that is unreactive avoids a complete crosslink thereby causing a weak polymer structure formation.…”

In this study, the impact of coated hollow microsphere (HMs) on syntactic foams (SFs) failure analysis is performed. The HMs was made from polystyrene beads and were coated with CaCO3 and cementite powder to produce the SFs by Vacuum Assisted Mould Fill Technique (VAMFT). The morphological analysis was performed using Scanning Electron Microscope (SEM) and the compressive test conducted using INSTRON 5982 machine model. From the results, the HMs failure mechanism showed the cementite surface coating enhanced the shellrigidity by 65%. The physical and compressive properties of the SFs increased with increase in % vol. fraction of the HMs. The SFs compressive modulus, flexural strength and tensile strength for the CaCO3 and cementite specimen are 470,44, 36 MPa and 582,48,41 MPa, respectively. The energy absorption characteristic of the SFs was enhanced by 14% and 25% for the CaCO3 and cementite HMs surface coating, respectively. But the optimal concentration for the SFs was 20% vol. weight for both HMs coating.

“…One category is polymer foam with open cells connected to each other. Examples include melamine-formaldehyde foam and epoxy foam [42,43,44,45]. The other category is closed-cell foam with separate cells, in which PS foam, polymethylacrylimide foam, and PE foam are examples [46,47].…”

Polymer foams have low density, good heat insulation, good sound insulation effects, high specific strength, and high corrosion resistance, and are widely used in civil and industrial applications. In this paper, the classification of polymer foams, principles of the foaming process, types of blowing agents, and raw materials of polymer foams are reviewed. The research progress of various foaming methods and the current problems and possible solutions are discussed in detail.

“…The pure Al foams are subjected to many restrictions in engineering applications owing to its low mechanical properties, such as the plateau stress and the yield strength. For the past few years, the Al matrix composite foams (AMCFs) with microreinforcement (like fly ash, SiC, Al 2 O 3, carbon fibres, expanded particles, and cenospheres) have attracted much attention. Du et al conducted the compressive tests using Al syntactic foams reinforced by 1‐vol% SiC, showing that the yield stress and energy absorption capacity improve 194.5% and 69.4% compared with pure Al foams, respectively.…”

The compression‐compression fatigue performance of carbon nanotube (CNT) reinforced aluminium matrix composite foams (AMCFs) were investigated. The ε‐N curves of AMCFs are composed of three stages (the elastic, strain hardening, and rapid accumulation stages), while the fatigue strain of AMCFs accumulates very rapidly in stage III compared with Al foams. The fatigue strength of AMCFs with CNT contents of 2.0, 2.5, and 3.0 wt% increases by 6%, 44%, and 102% than Al foams, respectively. Different from Al foams' deformation of layer‐by‐layer, the main failure modes of AMCFs are the brittle fracture and collapse of pores within significant shear deformation bands under fatigue loading. The uniform distribution of CNTs and good interfacial bonding of CNTs and Al matrix is the important factor for the improvement of fatigue properties of AMCFs.
