Influence of fillers and fibre reinforcement on abrasive wear resistance of some polymeric composites

摘要: Abstract Fillers and fibre reinforcement increase the strength stiffness of a polymer, hence are effective in reducing wear dry sliding conditions involving adhesion transfer or fatigue. However, abrasive wear, such reinforcements less and, some cases, rate. For better understanding this, studies were carried out on four types polymers their filler- and/or fibre-reinforced composites, abrading polymer pins against an surface silicon carbide paper fixed grit size. In most specific rate decreased with load. Except for bronze-filled polytetrafluoroethylene (PTFE), all fillers (carbon, graphite, PTFE MoS 2 ) as well short glass fibres increased wear. These results may be attributed to greatly ultimate elongation fracture which turn is key factor performance. The extent counterface modification multipass was observed another important performance composites. Worn pin surfaces also studied scanning electron microscopy.
