This paper builds a conductivity percolation model for the carbon nanofiber composite materials. The model is based on the randomly generated cylinders, which model the nanofibers, forming clusters through the tunneling effect. When a cluster spans the substrate from one side to the opposite side, percolation happens. Preliminary simulation results demonstrate the percolation phenomenon when the volume rate of the nanofibers in the composite exceeds a critical value. The relationship between the nanofibers' aspect ratio and the critical volume rate is also studied.
