For the investigation of electrical properties of samples produced with the three-roll mill, SWCNT/epoxy dispersions were used to produce bar-shaped samples (5 × 2 × 40 mm) in a silicone mold. For each experimental configuration, the electrical resistivity of six samples was measured using the four-point method.

The epoxy∕clay compound is then mixed with EPI-CURE 3282 curing agent by a custom made molding setup and injected into a disk shaped mold cavity. Upon completion of curing, nanoclay dispersion is quantified on a sample cut along the radius of the composite disk.
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.
However, a combination of ultrasound sonication and three roll milling on the other hand, resulted in poor clay exfoliation; the sonication process degraded the polymer network, which adversely affected the nanocomposite final properties relative to the unmodified E-glass/epoxy polymer.

Three roll mill is an extremely effective dispersion tool for nanocomposites containing fiber-like filler such as carbon fiber, glass fiber, carbon nanotube etc.
Processing of Clay/Epoxy Nanocomposites with a. Held in Boston, Massachusetts on December 2-6,, In the present study, a three-roll mill machine was used to disperse/exfoliate the nanoclay particles, process clay-epoxy nanocomposites are: direct mixing and solution mixing [4-71. Read more
The clay-resin mixture was further processed using the calendar process commonly referred to as three roll milling. The three roll milling machine generally consist of three adjacent cylindrical rollers each running at different velocities. The resin was fed into the rollers as depicted in Figure 5. As the resin passes between these rollers, it ...
In this study XRD was used to measure the dispersion state of clay particles in epoxy. A series of nanocomposites with 1 wt%, 3 wt% and 5 wt% nanoclay was fabricated using mechanical stirring and three roll mill methods. The overlaid of XRD patterns of pure Epikote 828 polymer, Cycom 977-20 polymer and polymer-nanoclay nanocomposites were produced.
Since the three roll mill mixing is not a continuous process, the material from the apron was collected and fed back to the feed and center rolls after each complete pass of the material. At the beginning of the mixing, the epoxy resin became viscous and opaque due to the incorporation of clay particles.

The more uniform distribution and smaller mean particle-particle distances would better constrain expansion of the majority of the molten epoxy network.In contrast to 30A, the I30.E nanocomposites exhibited a much smaller impact on T g (DT g w5 8C, Table 3) due to processing differences.
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.
