Abstract
For the preparation of composite materials environmentally friendly natural nano particle silica derived from rice husks has as strengthening of Iraqi natural materials in a ratio of (2, 4, 6, 8%) on the polyester resin body and polystyrene separately. Natural silica was identified using XRD and FTIR by measuring the proportion of SiO2. 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 polyester resin body results are increase the impact resistance values, hardness, and bending rigidity. As in the case of polystyrene composite, the ratio of 2% is the optimized percentage of strengthening, which lead to increased values of impact , bending and hardness. these study also showed ability of natural silica composite mechanical properties to gives resistance to stress conditions during use .
