In this research, treated titanium dioxide in the contents of 0.1-0.5 wt % was applied into epoxy resin in order to toughen it. Vibracell ultrasonic with various electric power and times was used to disperse the particles successfully. It was found that the epoxy nanocomposites with 0.1 wt % of silane-treated nano titanium dioxide provided the highest impact strength and fracture toughness (KIC) of 69.4 J/m. and 2.18 MPa.m1/2, respectively, while, those properties of the neat epoxy were 41.3 J/m. and 1.16 MPa.m1/2. However, the impact strength and fracture toughness of nanocomposites decreased by about 50 % and 8 %, respectively by further increasing amount of treated Nano titanium dioxide particles 0.2 to 0.5 wt %.
