Abstract
A paper-making machine includes a traveling substrate and a roll carrying the substrate. The roll includes a carbon fiber shell, a ceramic layer over the shell, and a polytetrafluoroethylene layer over the ceramic layer. The polytetrafluoroethylene layer defines an outer surface of the roll. The ceramic layer intermittently extends through the polytetrafluoroethylene layer to the outer surface of the roll.
