‘Fluoroplastic–Multi-Walled Carbon Nanotube’ Composites: Structural, Mechanical, and Tribotechnical Characteristics

The paper studies the production of ‘fluoroplastic–carbon nanotube’ composites, analyzes their structure, and determines their mechanical and tribotechnical characteristics. The properties of the composites depending on the reinforcement content are examined. It is established that addition of only 3% carbon nanotubes significantly increases the hardness and Young’s modulus while the wear becomes two orders of magnitude lower under friction without lubrication. The structure of ‘fluoroplastic–carbon nanotube’ composites is analyzed in detail. A mechanism whereby carbon nanotubes influence the mechanical characteristics and wear resistance is proposed.
