Effect of Lubrication on the Tribological Properties of a Friction Pair Composed of Alumina-Steel Composite Fibers

Resumo

The coefficient of static friction is used in calculations of the tension on fibers during their rewinding and twisting. Composite fibers made of alumina are a new product for the Russian textiles industry, and their mechanical properties are in need of further study. This article presents results from an experiment performed by the inclined-plane method to determine the coefficient of static friction (CSF) for friction pairs: lubricated and non-lubricated composite alumina-steel fibers; the effects of a lubricant on the CSF and its stability are also evaluated. The results of the investigation are being used to design a technology for obtaining doubled fibers of alumina.
