Exploring synergistic and antagonistic interactions of MoS2 and multi-wall carbon nanotube additives in a composite top-of-rail friction modifier
The effects of MoS2 and Multi-Wall Carbon Nanotube (MWCNT) additives onto thermal, mechanical and tribological properties of the vinyl ester polymer-matrix composites were systematically studied. Monocomponent and mixed additive compositions with concentrations ranging between 0 and 3 wt% showed com...

| Sumario: | The effects of MoS2 and Multi-Wall Carbon Nanotube (MWCNT) additives onto thermal, mechanical and tribological properties of the vinyl ester polymer-matrix composites were systematically studied. Monocomponent and mixed additive compositions with concentrations ranging between 0 and 3 wt% showed complex behaviours. Tribological behaviour of steel-steel roiling-sliding simulating wheel-rail contact in presence of the composites significantly varied depending on the additives’ composition. Wear of the disks was mainly controlled by the composite capacity to form transfer film. |
