Characterization and Mechanical Properties of Epoxy Resin Reinforced with TiO₂ Nanoparticles

Epoxy resins with widely different mechanical properties were used as matrices in which functionalized TiO2 particles were randomly dispersed to produce nanocomposites. These nanoparticles are 21 nm in diameter. They are dispersed in epoxy resin , using ultrasonication or magnetic stirring process for 5, 30 and 60 min. The composites with nanometer scale, TiO2 particles at 0.5, 1, 5 and 20% weight were characterized by hardness tests and tensile tests. The results are then compared with the neat epoxy resin.
