Scratch of rubber

What is it about?

Rubber components often subject to the surface scratch because of their relative movement with other counterparts. This work experimentally studied the scratch behavior of a typical rubber material. The surface mophology and the scratch damage modes of the samples were observed. Then the scartch mechanisms were analysed based on the damage modes and their correlation with the macro mechanical properties.

Why is it important?

The surface scratch not only seriously decreases the aesthetics of the rubber products, but also degrades their mechanical performance and eventually shortens their service life. The findings in this work help to deeply understand the scratch behavior of rubber materials and provide a valuable guidance for improving their scratch resistance.
