Percolation Model of Friction Wear for Carbon Plastics Based on Ultrahigh-Molecular-Weight Polyethylene

详细

A percolation model for two-component random materials, namely, the model of a random resistor grid (RRG) or an “ant limit” is used to describe the frictional characteristics of composites such as ultrahigh–molecular-weight polyethylene/carbon fiber. It is shown that the critical index of this model is determined by the structural parameters of the filler, whereas the RRG model describes equally well the results of frictional wear for both abrasive and fatigue mechanisms of wear.
