THE INFLUENCE OF REDUCING TEMPERATURE ON CHANGING YOUNG’S MODULUS AND THE COEFFICIENT OF FRICTION OF SELECTED SLIDING POLYMERS

Journal Title: Tribologia - Year 2018, Vol 279, Issue 3

Abstract

For the polymeric materials, changing of the temperature causes changes in mechanical and tribological properties of sliding pairs. The goal of the present study was to determine the change in Young's modulus and kinetic friction coefficient depending of the temperature. Three thermoplastic polymers, PA6, PET and PEEK, were tested. These materials cooperated in sliding motion with a C45 construction steel disc. As part of the experiment, the Young's modulus tests (by 3-point bending method) and kinetic friction coefficient studies (using pin-on-disc stand) were carried out. The temperature range of mechanical and tribological tests was determined at T = –50°C±20°C. Comparing the results of mechanical and tribological properties, there is a tendency to decrease the coefficient of friction as the Young's modulus increases while reducing the working temperature.<br/><br/>
