Study of impact resistant and flexural strength for epoxy composite reinforced by nano and micro materials of silica and titanium oxide.

In this study, the mechanical properties (impact test and flexural strength) for epoxy composite, and polymer-based composites were prepared by hand casting method. The composite material was prepared from epoxy resin as a base material supported by nano and micro materials from silica (Sio2) and titanium oxide (Tio2) with different weight fractions, the percentages of addition of nano titanium oxide (Ep+nano Tio2) with weights were (0.25, 0.50, 0.75, 1, 1.25) grams, respectively. The percentages of addition of nano-silica (Ep+nanoSio2) with weights: (0.1, 0.2, 0.3, 0.4, 0.5) grams, and the percentages of addition of micro titanium oxide (Ep+ microTio2) with different weights (0.3, 0.6, 0.9, 1.2, 1.5) grams, and the percentages of addition of micro-silica (Ep+microSio2) were (0.3, 0.6, 0.9, 1.2, 1.5 (grams) Weight fractions, and the flexural test (three-point) and the impact test were conducted on them. The results of the research showed that the values of the flexural strength of nanomaterials increase with increasing weight, as well as the impact resistance increases with a non-linear relationship with increasing the weights of the nanomaterial.
