In this work, the effect ofmulti-walled carbonnanotube(MWNT) contentsonthe rheological behaviors and mechanical interfacial properties of graphite nanoplate (GP)/epoxy nanocomposites was investigated. The results showed that the co-carbon fillers were homogeneously dispersed in the epoxy resins andMWNTs were intercalated into theGPlayers. The storagemodulus (G') and lossmodulus (G") of thenanocomposites was increased with the addition of MWNTs. This result was accompanied by an increase in elastic properties of the nanocomposites, resulted fromthe higher aspect ratio of theMWNTs. Andthemechanical properties of the nanocomposites were increased, as theMWNT content increased. It was noted that well dispersedMWNTs were strongly interacted with epoxy resins and worked as an effective reinforcement for the nanocomposites due to the flexible MWNTs compared with rigid GPs.
