Carbon nanotubes have received considerable attention because of their excellent mechanical properties. In this study, carbon nanotube - copper composites have been sintered by a mechanical mixing process. The interfacial bonding between nanotubes and the copper matrix was improved by coating nanotubes with nickel. Sintered pure copper samples were used as control materials. The displacement rate of nanotube-copper composites was found to increase at 200°C whereas that of nickel-coated nanotue-copper composites significantly decreased. The incorporation of carbon nanotubes and nickel-coated carbon nanotubes in the copper matrix decreased friction coefficients and increased the time up to the onset of scuffing compared with those of pure copper specimens.

The gap between the rotor and the mixer chamber wall is an important factor in determining filler dispersion in rubber compounds. The inner wall of a mixer will wear after working for a long time, which will cause poor filler dispersion and affect the quality of rubber products. In this study, MoDTC was added to carbon black as a kind of filler, and the effect on filler dispersion, the properties of the rubber product, and the friction and wear of rubber and metal in the mixing process were examined. Experimental data showed that after adding 3 phr of MoDTC, carbon black dispersion was greatly improved, the curing time was shortened, and the performance remained stable. It was also found that the Mo element of the compound with 3 phr MoDTC dispersed better than that of the other compounds. Most importantly, adding 3 phr of MoDTC greatly reduced the amount of wear on the metal during the mixing process. However, the opposite effect occurred when the MoDTC content was high. The method proposed in this study can not only improve filler dispersion in rubber but also reduce metal wear to prolong the service life of the mixing chamber when applied to an actual mixing process.

Multi Wall Carbon Nanotube

Cementitious composites reinforced with multi-wall carbon nanotube (MWNT) (MWFRC) were prepared with surfactant dispersion, ultrasonication, and subsequently high-speed mixing process. Fracture mechanical performance of the cured MWFRC was characterized according to three-point bending method (ASTM 399). It is found that the addition of nanotubes significantly improve the flexural strength, the stress-intensity factor of the nanocomosites with dispersed MWNT fiber, the maximal enhancement amplitude is near to 45%, 80% with respect to the baseline, respectively. The superior fiber bridging capability of the dispersed MWNTs upon the micro-cracks contributes to the reinforcement to cement matrix.
