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...
