Abstract:Using carbon fiber as electric heating skeleton， carbon black as conductive path， and aramid fibrid as auxiliary forming slurry， the carbon black/aramid fibrid/carbon fiber-based paper was fabricated via wet-forming process. The results showed that the paper comprising of 10% carbon black， 20% aramid fibrid， and 70% carbon fiber after impregnated with 15% phenolic resin and hot-press exhibited the best comprehensive performance. The tensile strength， tearing strength， and sheet resistance of the paper reached 1989 kN/m， 1057 mN， and 1.5 Ω/□， respectively. With supplied voltage of 8 V， the highest surface temperature of the paper after electric heating could reach 242.5℃.
