Abstract

In this study, the polymer epoxy matrix was reinforced by carbon nanotubes (CNTs) doped with graphene nanoparticles (Gr). The graphene-doped CNTs were used as received, and doping ratios were 32 wt. % and 52 wt. %, respectively. The purpose of the study was the investigation of the combined effect of graphene and CNTs on epoxy matrix. The reference (neat epoxy matrix) and 0.5 wt.% filler added nanocomposites (32Gr-CNT/EP and 52Gr-CNT/EP) were manufactured to characterize the hardness and thermal performance. Vickers microhardness testing method, thermogravimetry analysis (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC) were applied. Approximately 15.63% and 27.50% increments were obtained in the microhardness of the 32Gr-CNT/EP and 52Gr-CNT/EP nanocomposites, respectively. The thermal analyses revealed an increase in thermal stability, and high enthalpy values were obtained.  32Gr-CNTs addition into the epoxy increased the enthalpy value by about 40%. However, no significant change was found in glass transition temperature values by incorporating 0.5 wt. % CNTs doped with graphene nanoparticles.
