Investigation the Effect of Nano Silica Dioxide Additives on the Properties of Epoxy Resin for Using in Industrial Applications

Abstract

The addition of ceramic nanoparticles to the polymer resin enhances the performance of the composite, enabling the use of such materials in industries such as automobiles and aircraft. This work aims to evaluate the characteristics of epoxy resins by introducing (1%, 3%, 5%, and 7% wt. nano dioxide silica). Using the "hand lay-up " process, about 125 samples were prepared for conducting tests (Hardness, Tensile strength, Impact, Water Absorption) and analyzing results by (SPSS-Scheff). The addition of 7% nano-silica dioxide particles to epoxy considerably raises the hardness values (85.350+.5150 shore D), according to the hardness results. The best average values of the tensile strength and impact (292± 2.828MPa, 54.00 ± 2.828 J/m2) were at the samples (Epoxy- 3% nano-silica dioxide) when compared with other samples. The values of elongation at break reduce through rising concentration, weight fractions of nano-silica dioxide in epoxy, and the best average values of the elongation at break (3.150± .2300 %) were at the samples (Epoxy- 1% nano-silica dioxide). The percentage of water absorption values improved by increasing the weight fraction concentrations of nano-silica dioxide in epoxy, and the best water absorption percentage was (.017 ±.003414%) in the samples (epoxy-1% nano-silica dioxide). Statistically, very large variations were observed of hardness, tensile strength, elongation at break, impact strength, and water absorption (Sig 0.01, 0.04, 0.003, 0.02, and 0.002) respectively, and this indicates an improvement in the properties when addition nano-silica dioxide to the epoxy resin

Improved Mechanical Properties of Basalt and Glass Fibre Reinforced Polymer Composite by Incorporating Nano Silica

“…In summary, the impact strength's interplay with nano silica weight percentages reveals a clear trend of enhancement up to 1 wt% and subsequent decline at 3 wt% and 5 wt%, attributable to nano silica's inclination to aggregate. This investigation underscores the significance of precise nano silica dispersion control in optimising composite properties [10], [16]. Meanwhile, for GFRPC, we can see from Figure 3 that a distinct trend emerges in impact strength variations across diverse nano silica weight percentages within the composite.…”

“…Nano silica can enhance the compression strength of composites by reinforcing the matrix material, thereby reducing the risk of compressive failure. Incorporating nano silica can significantly improve composites' mechanical properties, including increased strength, stiffness, and toughness [10]- [12]. Nano silica is lightweight, and its addition to composites can enhance its performance without adding excessive weight, making it attractive for applications where weight is critical.…”

Experimental investigation and statistical modelling for assessing the sliding wear of Futilized Filament Fabrication (FFF) fabricated parts

“…In the current work, the objective is to investigate the influence of parameters of printing which are (layer's thicknesses, printing speed, infill pattern) on the wear resistance of the parts. These parameters have a major effect on the wear resistance of the model [22]. So, these parameters are chosen for the current work.…”

Investigation on impact properties of basalt and glass fiber reinforced polyester composites filled with nano silica

“…Its incorporation can improve mechanical strength, thermal stability, flame resistance, and barrier properties, among other benefits. The small size and large surface area of nano-silica particles enable them to interact effectively with the matrix material, promoting load transfer and reinforcing effects [11], [12]. Nano silica's strong interaction with the matrix enhances the composite's stiffness, strength, and toughness.…”
