High-performance carbonaceous nanofiller (MWCNT) reinforced epoxy nanocomposites at different compositions were synthesized using the ultrasonication dual mixing method. The static and dynamic mechanical properties of the nanocomposites were examined. At 0.8 wt.% of nanofiller, the epoxy nanocomposite greatly improved in tensile strength by about 22.1% and Young's modulus by about 18.5%. The dynamic mechanical analysis showed a significant improvement in the storage modulus of about 19.1% and glass transition temperature of about 15.1% of the epoxy nanocomposite. This improvement may be attributed to the formation of an effective interface between the epoxy and MWCNT. The static and dynamic mechanical properties of the epoxy matrix were significantly improved as a result of the homogenous dispersion of carbonaceous filler in the epoxy matrix.
