Abstract. The authors present a study on using 3D roughness parameters for assessing the quality of worn surfaces of polymeric composites. A set of three plates was tested under water lubrication in contact with a steel disc, being tested at 2.5m/s (the sliding speed at plate center) and average pressure 2.02 MPa. The plates (6 x 20 x 30 mm) were made of PTFE composites with glass fibers (0% for the polymer, 15%, 25% and 40%, respectively).
