Viscoelastic and mechanical properties of multi walled carbon nanotube/epoxy composites with different nanotube content

► The tensile strength and modulus for 2wt% MWNT increased by 17% and 23% respectively. ► DMA results indicated a 46% improvement in storage modulus in 0.5 wt% MWCNT/epoxy at room temperature. ► The viscoelastic properties modified in the β and α relaxation. ► The addition of the MWNT did not have any effect on the β relaxation temperature.
