STUDY ON THE MECHANICAL AND TRIBOLOGICAL PROPERTIES OF GLASSFIBER REINFORCED POLYETHYLENE COMPOSITES

Tribological behavior of glass fiber reinforced HDPE(GF/HDPE) composites was studied,focusing on the effects of the content and orientation of glassfibre on the mechanical and tribological properties of the polyethylene based composites.Experimental resups showed that fiber content and orientation have great influences on the tribological behavior of the composite.The wear loss is the least in the direction vertical to fibers orientation,and the fiction coefficient is lower in the direction parallel with fibers orientation.HDPE composite reinforced by 30% glassfiber has good comprehensive mechanical and tribological properties,which can be a good candidatefor the tribological applications under severe conditions.
