Silicone Rubber Adhesion and Sliding Friction
- 1k Downloads
Using a Leonardo da Vinci experimental setup (constant driving force), I have studied the low-speed sliding friction for silicone rubber on a smooth polymer substrate. The friction force depends nonlinearly on the load, which I attribute to the influence of adhesion on the area of real contact. The experimental results are analyzed using the Persson’s contact mechanics theory, and the calculated dependency of the area of real contact on the load agrees very well with the experimental results.
