摘要：

The purpose of this study was to investigate the influence of adding different volume concentrations of titanium dioxide (TiO2) nanoparticles to an Araldite LY 564 epoxy resin. In order to characterize the nanoparticles toughening effects, compact tension specimens were used to determine the plane strain fracture toughness (K-1c). Additionally, elastic modulus, tensile strength, and maximum sustained strain were measured in mechanical tensile tests. Composites were analyzed by means of electronic microscopy, both TEM and SEM, to check the dispersion quality of the nanoparticles in the polymer matrix and to study the observed toughening mechanisms of the fillers. Addition of TiO2 nanoparticles could simultaneously improve the stiffness and the toughness of the epoxy resin. POLYM. COMPOS., 31:1241-1246, 2010. (C) 2009 Society of Plastics Engineers
