Dry Sliding Friction Analysis and Wear Behavior of Carbon Nanotubes/Vinylester Nanocomposites, Using Pin-on-Disc Test

摘要

Dry sliding friction and wear behavior of single-wall (SW) and multi-wall (MW) carbon nanotubes (CNTs)/vinylester composite have been investigated, under several loads and sliding speeds. Three different contents (0.1, 0.15 and 0.2 wt. %) of SWCNT and MWCNTs have been dispersed into the vinylester resin in order to obtain polymer nanocomposites. The present study discusses the coefficient of friction, specific wear rate and friction stability of vinylester composites with different CNTs content, using a pin-on-disc test. The friction and wear experiments were carried out following 3 loadsx3 speeds, as test parameters. The best combination of friction and wear properties was found with the nanocomposite containing 0.2 wt. % MWCNT.
