Viscoelastic and mechanical properties of multi walled carbon nanotube/epoxy composites with different nanotube content
Graphical abstract The pulled out nanotubes and weak interfacial interaction between epoxy and nanotubes improve the damping properties. Display Omitted Research highlights ► 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.
Abstract The viscoelastic and mechanical properties of composites multi walled carbon nanotube (MWNT)/epoxy at different weight fractions (0.1, 0.5, 1 and 2wt.%) 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 0.5wt.% 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.
