This paper investigates the effect of graphene nanoplatelets (GNP) on tensile and fracture toughness properties of an epoxy polymer. The GNP filled epoxy nanocomposites were prepared using a combination technique of solution compounding and high-shear milling with three different GNP loadings; 0.1 wt%, 0.2 wt% and 0.3 wt%.

A three-roll mill was used to disperse/exfoliate the clay nanoparticles in an epoxy matrix. The compounding process was carried out with varying clay contents (1–10 wt.%). The technique was found highly efficient and environmentally friendly in achieving high levels of exfoliation and dispersion within a short period of time.

La-SWNTs were then mixed with ultraviolet-curable epoxy using a three-roll mill machine to achieve a well-dispersed nanocomposite. The nanocomposites were then infiltrated within the empty channels at high pressures to induce shear. High shear flow infiltration of nanocomposites will cause the CNTs to be aligned in the direction of the channels ...

Common dispersion methods such as ultrasonic sonication, planetary centrifugal mixing and magnetic dispersion have been used extensively to achieve moderate exfoliation of nanoparticles in polymer matrix. In this study, the effect of adding three roll milling to these three dispersion methods for nanoclay dispersion into epoxy matrix was investigated.

Effect of nanoclay on the thermo-mechanical properties of BT250E-1 epoxy resin is investigated. Nanocomposite parts containing 0, 2 and 10wt. % of Cloisite ® 30B nanoclay are fabricated by copulverization of nanoclay with epoxy resin at −25°C. Desired amounts of solid epoxy resin and nanoclay are placed into a grinder and copulverized for 20 seconds.

Three different loadings of 0.5 wt.%, 1.5 wt.%, and 3 wt.% of C15A, respectively, are used as reinforcement. Results from the ball-on-disk wear tests showed that nanocomposites reinforced with 1.5 wt.% of C15A exhibited best wear resistance and lower coefficient of friction (COF), with C15A reducing the wear rate by 41% and the COF by 38%, …
