TFE SLIDING SURFACES IN BRIDGE BEARINGS

Tetrafluorethylene (tfe) is used widely to provide a sliding surface in a bridge bearing. This is due mainly to the material's low frictional property. This report presents the state-of-the-art of tfe sliding bearings. Parameters which may influence the coefficient of friction of tfe are discussed, and those parameters whose influences are not well documented in the literature are identified. (Author/TRRL)
