“…[8][9][10] Regarding the use of SF in polymeric materials, good research has been accomplished, which will be mentioned in this section. [11][12][13][14][15][16] Pandian and Jeilani 11 interrogated the effect of waste SF addition at various contents on the dynamic mechanical behavior of jute fibers/epoxy composites and evinced that by adding 2 wt.% SF particles, the storage modulus and enhanced by 7% compared with unmodified composites.…”

“…By adding further SF particles a significant reduction in mechanical properties was observed due to the unfavorable distribution of these particles within the polymer matrix. In the research of Almadny et al 13 the decrement in wear rate was obtained by adding SF and fly ash particles. In the case of SF particles In the case of fly ash addition, the at least wear rate was at 15%, and at higher contents, the wear rate increased.…”

In this study, the effect of the addition of silica particles modified with silane agent on the mechanical properties of basalt fibers‐epoxy composites were studied with the interlayer shear strength (ILSS) test. In the first stage, silica fume particles were synthesized using the sol‐gel method and surface modified using tri mercaptopropyl trimethoxy silane agent. The results of the characterization showed that the synthesized powder is nanometric scale, amorphous and high purity. The surface‐modified silica fume particles (0, 2, 4, 6 wt.%) were distributed inside the epoxy matrix using a mechanical stirrer and ultrasonic waves. The hand lay‐up method was used to fabricate composite samples, then the effect of adding these particles on the mechanical properties of basalt fibers‐epoxy composites under interlayer shear loads was studied. The results of the research indicated that the addition of silica fume particles has a significant effect on improving the mechanical properties of basalt fibers‐epoxy composites, and the greatest improvement in mechanical properties was achieved by adding 4 wt.% of modified silica fume particles. In the case of composites without SF particles, the shear strength was 34 MPa, which was increased to 40 MPa by adding 4 wt.% of SF particles (about 20% improvement). On the other hand, results demonstrated that the optimal distribution of silica fume particles within the polymer matrix performs an impressive role in improving the mechanical response of composite samples.Highlights The use of silica fume in the polymer composite is one of the research innovations. Silica fume is a super‐fine spherical powder that is collected as a by‐product. The silane is used to better distribute and optimal interaction of the silica fume in epoxy. Sol‐gel is one of the methods to synthesis of silica fume. ILSS test was done to investigate the strength of the interface of basalt fibers and epoxy.

Silica is considered one of the most prevalent components in the Earth’s shell and is synthesized for use in technological applications. Nevertheless, new methods for finding a better, cheaper, and more ecologically friendly supply of silica with less energy consumption are unavoidable. This study investigates whether nanopowders made from waste with a great silica amount (fly ash and glass) can be utilized as fillers in an epoxy glue to enhance its characteristics. Four different contents (5, 10, 15, and 20 wt%) of nano–fly ash, nanoglass, and nanosilica powder were introduced into the samples. Fourier transform infrared analysis, differential scanning calorimetry analysis, viscosity testing, and microhardness testing were conducted for nanoglass/epoxy and nano–fly ash/epoxy samples, which were compared with the silica/epoxy samples. Results indicated that the nanoglass and nano–fly ash powder have the same impact as nanosilica on the characteristics of epoxy. The hardness and viscosity of epoxy increased with the increase in the added filler. At 20 wt%, the hardness value of the nanoglass/epoxy composites was greater than that of the nanosilica/epoxy and fly ash/epoxy composites by about 15% and 7%, respectively. The results also indicated that the highest viscosity values were obtained when using nano–fly ash powder of 20 wt%. Furthermore, the modification of the epoxy by the nanoparticles had no significant effect on the values of the glass transition temperatures.
