Effect of surface temperature on tribological behavior of PTFE composites

Abstract

Tribological behavior of PTFE is highly affected by fillers used to improve its mechanical characteristics and depends on the ability of the material to maintain its integrity in the working conditions. Specifically, in the case under study, the heat generated by friction was modelled as a heat flow coining from a source at the contact surface in static condition. Considering that a heat flow is also supplied to the samples during a Differential Scanning Calorimetry (DSC) analysis, where crystallinity of material is evaluated, a correlation between thermal characteristics of the material, its structure and tribological behavior is presented. © 2011 WIT Press.
