“…Hollow glass microspheres were originally designed to decrease evaporation of oil and petroleum in large containers and as a means to increase buoyancy in ships and submarines. Hollow glass microspheres have more recently been exploited in the aeronautical, aerospace, automotive, civil and industrial engineering, and electronics industries as syntactic foams [9][10][11][12]. Incorporation of hollow glass microspheres as filler in polymeric matrixes to produce syntactic foams results in unique composite properties including good shear stiffness and strength, fatigue and impact resistance, low density, and high strength to weight ratio, which have largely facilitated their widespread application [13].…”

“…Many researchers have investigated the flexural properties of various syntactic foams [3][4][5][6]. Results of these researches showed that the addition of microballoons could reduce the densities of materials.…”

The aim of this study was to investigate the flexural behaviours of syntactic foam reinforced by warp knitted spacer fabric (SF-WKSF). Seven kinds of SF-WKSF samples were fabricated by warp knitted spacer fabric (WKSF) with structural parameters including surface layer structures, inclination-angle and fineness of spacer yarns, different microballoons types and contents. The flexural tests were carried out and the bending properties of SF-WKSF were analysed based on the strength and modulus values obtained from the test results. It is indicated that the SF-WKSF shows higher flexural strength and modulus compared to neat syntactic foam with almost no impact on the density of composites. The results also demonstrate that the surface layer structure, inclination-angle of spacer yarns, microballons content and type have significant effects on the flexural responses of SF-WKSF. The composites exhibit better antibending capacities by selecting larger inclination-angle, closer surface layer structure, higher density and relatively higher content of S60HS microballoons.

“…Most available studies on the mechanical response of PSF focused on their quasi-static compressive loading ( [8], [9]) or compressive and tensile loading ( [3], [10], [11]). Some research has focused on the high strain rate response in compression, and these studies reported significant strain rate sensitivity ( [12][13][14][15][16][17]).…”

Quasi-static and dynamic experiments are conducted to characterise the mechanical response of a syntactic foam comprising hollow glass microballoons in a polyurethane matrix. Stress versus strain histories are measured in uniaxial tension and compression as well as in pure shear, at strain rates ranging from quasi-static in-situ tests are conducted to visualise the deformation mechanisms in tension and compression. The material displays a pronounced sensitivity to the imposed strain rate and relatively high tensile and shear ductility at both low and high strain rates. A tension/compression asymmetry is displayed in quasi-static tests but is lost at high rates of strain.
