In the present investigation, we have studied effect of inclusions size on mechanical properties of nanocomposite materials containing SC-15 epoxy resin and TiO2 particles. The size of particles varied from macro (0.02mm) to nano (5nm) scale. The particles were infused into the part A of SC-15 through sonic cavitations and then mixed with part B of SC-15 using a high speed mechanical agitator. The trapped air and reaction volatiles were removed from the reaction mixture using high vacuum. Three-point bending tests were performed on unfilled, 0.5wt.%, 1.0wt.% and 1.5wt.% TiO2 particles filled SC-15 epoxy to identify the loading effect on mechanical properties of the composites. Experimental results show that, micro sized particles have little effect on modulus and strength of epoxy at such low loading, and modulus and strength increased as the size of particles decreased to nano scale. Results also show that 1.0wt% nanoparticles reinforced system exhibit the highest mechanical performance. Higher than 1.0%, strength of composite decreased because of poor dispersion.
