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
