Electrical Responses of Carbon Black Filled Silicone Rubber to Uniaxial Cyclic Loading
The electrical responses of carbon black filled silicone rubber to cyclic loading were investigated by electrical resistance measurements. Results indicated that the resistance of specimen appeared irreversible decrease in the earlier cycles of the first group test. The relation of the resistance and uniaxial cyclic loading are repeatable after 5 cycles while the irreversible micro-cracks are almost no longer generated. The resistance of each effective conductive path, the number of effective conductive path and average effective cross-sectional area of the insulating film between the adjacent conductive particles are key factors of the piezoresistivity.
