Abstract
$TiO_2$ nanoparticle can be used for the improvement of performance of the epoxy resin composites. In this study, the effect of the size of $TiO_2$ nanoparticle on the mechanical properties for the epoxy resin composites was investigated. The size of $TiO_2$ nanoparticle was easily controlled by heat treatment. The heat treatment of $TiO_2$ nanoparticle was conducted between $700^{\circ}C$ and $900^{\circ}C$. The obtained size of $TiO_2$ nanoparticle was 20 nm, 100 nm and 200 nm respectively. As the diameter of $TiO_2$ nanoparticle is smaller, the epoxy resin composite specimen showed higher tensile strength. It was also found that Vickers hardness of epoxy resin was increased by the addition of $TiO_2$ nanoparticle. But the size of $TiO_2$ nanoparticle did not strongly affected to the Vickers hardness of this material. The fracture surface of epoxy resin showed clear difference by the size of $TiO_2$ nanoparticlet.
