▎ 摘  要

This article deals with the influence of titanium dioxide (TiO2) and graphene nanoplatelet (GnP) on epoxy's tribological, compressive, surface hardness and thermal response. Initially, the TiO2 and GnP particle morphology was analyzed. A ball-on-disc testing apparatus was used to evaluate the wear and frictional behavior of the nanocomposites. The worn-out surface micrographs of tested nanocomposite samples were analyzed using a scanning electron microscope (SEM). The compressive response of the nanocomposite samples was analyzed at in-situ temperatures of 30, 75 and 120 degrees C. The hardness of the nanocomposite sample's surface was also examined, along with the influence of nanofiller addition on samples' glass transition temperature (T-g). The elemental-colored mapping was used to verify the proper dispersion of the nanofiller in the epoxy. It was observed that the inclusion of 2 phr (per hundred resin) by weight of TiO2 along with 2 phr GnP showed a decrement of 65.17% in wear volume and an increase of 17.37% peak compressive stress value at 30 degrees C compared to neat epoxy. An increment in the T-g was also observed with the inclusion of nanofillers in epoxy. Significant outcomes of the study conducted on the nanocomposite samples are discussed in this article.
