Friction and Wear Characteristics of Composite Materials for Architectural Membrane

Abstract

The purpose of this paper is to clarify the friction and wear properties of the architectural membrane sliding against the steel. Different matrix materials for the architectural membrane as PVDF (Polyvinyliden Fluoride), PVF (Polyvinyl Fluoride) and PTFE (Polytetra Fluore Ethylen) were prepared and fixed on a steel disk. Some steel pins were used in the pin-on-disk sliding test against steel disk covered with membranes. Friction tests were conducted with different load and sliding velocity as 2-60 N and 0.02-0.20 m/s, respectively. The results showed that the friction coefficient is independent on the sliding velocity for all materials. On the other hand, contact load changed the friction coefficient well, especially for the PVDF. Friction coefficient of PVDF composite material sliding against bearing steel is lower than PTFE and PVF. On the other hand, PTFE showed lowest friction of all when μpv is more than 0.005 MPa m/s. Comparing with three membrane materials, PTFE membrane shows the lowest friction coefficient and highest wear resistance of all.
