Effect of Different Fillers on Microstructure and Mechanical Properties of Ultrahigh Molecular Weight Polyethylene Composite

Abstract:

Three fillers i.e. micro glass bead, nano-montmorillonite and graphite at 8wt% were respectively filled into ultrahigh molecular weight polyethylene (UHMWPE). The microstructure, mechanical properties were investigated. The results indicated that: The performances of three kinds of composites, such as morphology, tensile strength, impact strength, elongation at break and fraction wear, were in great difference. The bonding of interface between glass bead and UHMWPE was not firm, but nano-montmorillonite and graphite as filler dispersed in matrix evenly and coupling tight. Due to filling the filler, the tensile strength, impact strength and elongation at break decreased in varying degree compared with that of simple UHMWPE, but impact strengths reduced only a few; however the wear resistance of composite filled by graphite was improved obviously.
