Abstract
This study is about the mechanical properties of epoxy composite reinforced with nano $TiO_2$ particle. Tensile strength, fracture toughness, vicker's hardness and Izod Impact test were carried out to investigate the effect of particle size and content of $TiO_2$ on the mechanical properties of $TiO_2$/epoxy composites. The results showed that the strength of the $TiO_2$/epoxy composites were higher than that of the pure epoxy. The best improvement of tensile strength was achieved in case of the particle size was 21 nanometer and the content was 3 weight percent. However, the Izod Impact value and the Vicker's hardness of $TiO_2$/epoxy composites showed no clear tendency.
