Effects of Particulate and Fibrous Carbon Filler Combinations on the Tribological Behavior of a Polyacetal Composite under Water Lubrication

This study focused on the effects of combinations of fillers comprising particulate and fibrous carbon materials on the tribological behaviors of a polyacetal (POM) composite under water lubrication. The filler materials were rice bran ceramics (RBC) particles and carbon fibers (CFs). Friction tests...
