Determination of Mechanical and Friction Properties of Carbon Composites at Different Scale Levels

—A comprehensive study of the mechanical and tribological properties of composite materials developed for damping washers used in ball-screw pairs at the micro- and nanolevel has been carried out out. The study includes determination of the local elastic properties of elements of a composite material using atomic force microscopy, and integrated elastic properties, by indentation. The results obtained at the nano- and microlevels are compared. A method for determining the friction coefficient at the micro level has been developed. It is shown that the Amonton–Coulomb law is satisfied for the considered friction pair.
