The nanomaterial effect on the interfacial properties between glass, carbon, and their 1:1 hybrid fiber-bundle reinforced epoxy resin is evaluated based on fiber-bundle pull-out tests. Graphene and multi-walled carbon nanotubes (MWCNT) are incorporated in the interfacial region. Three contents of nanomaterials that including 0.1, 0.3, and 0.5 wt% are considered, and the temperatures are set as 25 and 150 degrees C during the pull-out tests, respectively. The interfacial shear strength (IFSS) of graphene and MWCNT filled interfaces is compared. Results indicate that both the two nanomaterials can improve the IFSS and shear toughness effectively. The IFSS of 0.3 wt% MWCNT filled glass-carbon/epoxy hybrid specimens is increased by 82% at 150 degrees C, which is the largest among all the specimens. According to scanning electron microscope (SEM) morphologies of fiber surfaces, the IFSS improvements are ascribed to the efficient stress transfer by the enhanced bonding performance after filling nanomaterials in the interphase.
