AbstractThe electrical properties of laminated rubber/carbon fibre facial conductive and heat generating sheet were investigated.The results showed that the curing process had direct effect on the resistance of conductive and heat generating sheet and the sheets in different sizes had different resistance decay reats during vulcanization;the shet possessed good heat circle stability and the RT-resistance kept constant after several heat circles;the linear relationships of voltage-current and power density-surface temperature existed;and the power stability could be obtained in long term service.
