     the viscoelastic and mechanical properties of composites multi walled carbon nanotube (mwnt)/epoxy at different weight fractions (0.1, 0.5, 1 and 2 wt.%) were evaluated by performing tensile and dynamic-mechanical thermal analysis (dmta) tests. the mwnt/epoxy composite were fabricated by sonication and a cast molding process. the results showed that addition of nanotubes to epoxy had significant effect on the viscoelastic and mechanical properties. however, the use of 0.5 wt.% increased the viscoelastic properties more significantly. concerning viscoelastic modeling, the cole–cole diagram has been plotted by the results of dmta test. these results show a good agreement between the perez model and the viscoelastic behavior of the composite.
