“…Herrera-Ramírez et al [136] have taken the advantage of both low density and thermal conductivity of HGMs, and high mechanical and electrical conductivity of carbon-based nanofillers, micro-and nano-sized fillers can be combined into a single composite material. In the searches of Ren et al [137] a high-temperature resistance buoyancy material HGMs/SiO 2 composite with the HGMs as the filler and the SiO 2 as the matrix was successfully prepared through a compression moulding process. Yang et al [138] used a Tm 3+ -Ho 3+ co-doped tellurite glass as the laser medium to build active microsphere laser resonators.…”

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.

“…Their main component is borosilicate, which is a lightweight material with a large specific surface area, stable chemical properties, high specific strength, and acoustic and thermal insulation. [17][18][19][20] Hollow glass microspheres were employed as fillers for syntactic foams; however, epoxy resins are organic materials, while hollow glass microspheres are inorganic materials. The significant difference in their polarities leads to poor interfacial bonding, which limits the performance of the resulting syntactic foams.…”

A syntactic foam was prepared from an epoxy resin matrix and modified hollow glass microsphere fillers. Modification by silane coupling agents with different molecular structures was analyzed, and the optimal content of the silane coupling agent was determined. The results demonstrated that all silane coupling agents enhanced the adhesion between the hollow glass microspheres and epoxy resin matrix, resulting in enhanced water absorption, compressive performance, tensile performance, and bending performance compared to those prepared using unmodified hollow glass microspheres. Among silane coupling agents with different end groups, the one with a sulfhydryl end group exhibited optimal modification for hollow glass microspheres. Among the silane coupling agents with different backbone structures, the one with silanol groups exhibited the optimal modification of hollow glass microspheres. Additionally, the performance of the syntactic foams was optimal when 6% of the silanol-containing coupling agent was used. The results demonstrated that syntactic foams prepared with hollow glass microspheres modified by silane coupling agents exhibited improvements in water absorption, compressive performance, tensile performance, and bending performance, compared with those prepared using unmodified hollow glass microspheres. Among silane coupling agents with different end structures, the one with a sulfhydryl group as end group showed the best modification effect on hollow glass microspheres. The water absorption was 0.35%, the compressive strength was 62.15 MPa, the tensile strength was 40.15 MPa, and the bending strength was 53.17 MPa. Among silane coupling agents with different backbone structures, the one with silanol groupsbonds showed the best results. Its compressive strength was up to 64.15 MPa, the tensile strength was 35.47 MPa, and the bending strength was 53.99 MPa.

“…[3] At present, the United States, Japan, France, Russia, China, and many countries have the technology to produce high-strength syntactic foams materials and have studied their manufacturing process, [4][5] mechanical properties, [6][7] and thermodynamic properties. [8][9][10] N. Movahedi et al [11][12] investigated the mechanical and corrosion behavior of closed-cell aluminum-alloy foams. Romanian scholars E. Linul and L. Marsavina [12][13] have tested the compressive mechanical properties of different foam based composites at low/high temperature conditions.…”

An experimental study was performed on a new composite material, namely, a hollow glass microsphere/epoxy resin composite material. As a new type of solid buoyancy material, the proposed composite material is promising for use in submersible, deep-sea oil risers. This composite material has many advantages, including the ability to bear extreme temperature, corrosion, and hydrostatic pressure up to tens of megapascals. In this study, the hydrostatic compression properties of six different mass filling ratio samples were tested based on an advanced triaxial testing system with varying temperatures. Some basic parameters, such as density, axial and radial stress-strain curves, and volume strain, were obtained. The elastic modulus and Poisson's ratio were subjected to nonlinear fitting. Additionally, the elastic-plastic performance was analyzed according to the residual strain. A new method to characterize the properties of the material is proposed. These data will be used to develop new constitutive models and to predict the structural strain in engineering applications under high hydrostatic compression.
