The effect of the mesostructure of Si_3N_4 particulates and PAI resin film on the wear of the film surface due to sliding motion of paper were experimentally examined in respect to the self-lubrication. And wear process of this hybrid resin film was simulated visually on the computer. We tried to examine wear mechanism by means of the visual simulation. The results were as follows. (1) Wear amount of mesostructural resin film due to the sliding of paper has been reduced approximately to one tenth as compared with conventional epoxy plastic film. (2) Rolling and sliding trace of Si_3N_4 has been observed over the film surface in the sliding direction of paper after sliding the paper. The trace that was found in this instance can be called as Meteoric Track. (3) We closely looked at the particle movement, made a simple model, and simulated visually. By this simulation, we could observed the particle behavior and meteoric track behavior of wear process which is not possible at actual experiment. (4) The change of wear volume in the simulation almost agreed with that of experiment. So, this simulation was suitable, and can analyze the Meteoric Wear. And, we propose the new evaluation expression of Meteoric Wear by modifying Rabinowicz's abrasive wear model.
