| Summary: | <strong>ABSTRACT</strong><br /> For the preparation of composite materials environ mentally friendly natural nano particle silica derived from rice husks has as streng thening of Iraqi natural materials in a ratio of(2, 4, 6, 8%) on the poly esterres in body and poly (styrene-co-butadiene) separately. Natural silica was identified using XRD and FTIR by measuring the proportion of SiO<sub>2 </sub>. AFM device was also used to measure the granular size of the silica nano particles. And the results of the study consistent with theoretical studies . Results also showed mechanical models composite. That added nano-silica of 6 % to poly esterres in body results are increase the impact resistance values , hardness, and bending rigidity. As in the case of poly (styrene-co-butadiene) composite, the ratio of 2% is the optimized percentage of streng thening, which lead to increased valuesof impact, bending and hardness. these study also showed ability of natural silica composite mechanical properties to gives resistance to stress conditions during use . |
