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℃. |
