The tribological properties of multilayer hybrid PTFE/Nomex fabric/phenolic resin composite with two fabric structure under water lubrication

Abstract

In this paper, two polytetrafluoroethylene (PTFE)/Nomex hybrid fabric structures with different weaving methods under various working conditions were studied. A pin-on-disk tribometer was used to test the friction coefficient (COF), and a scanning electron microscope (SEM) was used to analyze the wear surface. The results showed that COF of the two fabric structures was significantly different under dry sliding but similar under water lubrication. The wear amount of the two fabric structures was also different. Fabric structure influences the COF and wear amount via affecting the surface topography and the bonding force between layers.
