dc.description.abstract | The electrical properties of composite electroceramics are determined by the concentration, shape and distribution of filler phase in matrix. The carbon fiber-filled polymer was chosen as a model system and the electrical conductivity was measured as a function of carbon fiber content and the aspect ratio (AR) of the fibers to understand the percolation behavior of the composites. The composites of carbon fiber (1 similar to 9 vol.%) and thermoplastic polymer were fabricated in a mold press with the aspect ratio of carbon fiber varying between 4 and 10. The percolation threshold volume concentrations (V-c) of transition from the insulator to the conductor decreased as the fiber aspect ratio increased. With the fibers segregated at the polymer-polymer interfaces in the present study, V-c values were much smaller than those with the fibers randomly distributed in the matrix shown in other studies. The inverse relation between V-c and AR was found as expected. From the comparison with other experimental and simulated data, we concluded that the slope in 1/V-c versus AR plot is a strong function of fiber segregation. | - |
