PA6 composites with various contents of wood fibers were prepared. The effects of fiber content and ionic liquid surface treatment on the tribological behavior of PA6 composite were studied under different nominal pressures ranging from 50 to 300 N. The tribological mechanisms were discussed based on scanning electron microscopy inspections of the worn surfaces. The surface treatment of wood fibers improves the tribological performance of the neat polymer matrix. The modification can improve O/C and N/C on the surface of wood fiber, while the increase of nitrogen and oxygen content on wood fiber surface can improve the surface polarity of wood fiber and improve the infiltration and bonding between wood fiber and PA6 resin.
