The Tribological Properties of Polypropylene Composite Filled with DBD-Treated Carbon Fiber

Abstract

Dielectric barrier discharges (DBD) in ambient air are used on carbon fiber to improve the carbon fiber surface activity. Carbon fibers with length of 75 um are placed into the plasma configuration. The tribological properties of polypropylene filled with untreated and DBD treated carbon fiber are comparatively investigated. Results show that DBD treatment greatly improve the friction and wear properties of carbon fiber reinforced polypropylene composite (CF/PP).
