"Fluoroplastic-Multiwall Carbon Nanotubes" Composites: Structure and Mechanical and Tribotechnical Characteristics

Abstract

The paper studies the production features of "fluoroplastic–carbon nanotubes" composites, analyzes their structure, and determines their mechanical and tribotechnical characteristics. The properties of the composites depending on the content of the hardening phase are examined. It is established that addition of only 3% carbon nanotubes significantly increases the hardness and Young"s modulus and decreases wear by half under friction without lubrication. The structure of "fluoroplastic–carbon nanotubes" composites is analyzed in detail. A mechanism whereby carbon nanotubes influence the mechanical characteristics and wear resistance is proposed.
