Frictional Instabilities in Polymer-Polymer Sliding

The effects of surface roughness, normal load, sliding velocity, and silicone oil content of Acrylonitrile-Butadiene-Styrene (ABS) polymer on static and kinetic friction were studied in a pin-on-disk apparatus in dry sliding. The results indicated that stick-slip occurred on smooth surfaces, at high...

Description
Summary:The effects of surface roughness, normal load, sliding velocity, and silicone oil content of Acrylonitrile-Butadiene-Styrene (ABS) polymer on static and kinetic friction were studied in a pin-on-disk apparatus in dry sliding. The results indicated that stick-slip occurred on smooth surfaces, at high loads for materials which had a negatively sloped friction-velocity curve at low velocities, and a positive slope at high velocities. The polymers containing silicone oil had lower friction values and required higher normal loads to cause frictional instabilities. Presented as a Society of Tribologists and Lubrication Engineers paper at the ASME/STLE Tribology Conference In San Diego, California, October 19-21, 1992
