Short and Long Term Effects of P.F.P.E.(k) Oils and Greases on Vibration and Friction Between Various Automotive Materials

In an effort to better understand the effectiveness and durability of P.F.P.E.(k) fluids in solving automotive squeak and vibration problems, a test method has been developed that permits an accelerated, quantitative assessment of their impact on a variety of commonly used automotive materials. This paper describes the apparatus and method developed to conduct this testing, as well as presenting data generated to date as the impact of key fluid properties and parameters on various combinations of materials are explored. This information should allow automotive engineers to solve these problems with a much greater degree of precision and confidence.
