开展了碳纤维纸张制备及电学性能的研究。研究结果表明:为了获得匀度相对较好的碳纤维纸,植物纤维纸浆适宜的打浆度选择45~50°SR区间;在碳纤维含量在5%时,碳纤维纸张的耐破指数不低于5k Pa·m~2/g,撕裂指数均大于8.0m N·m~2/g,裂断长都在6km以上,所以碳纤维含量选择5%较为合适;在碳纤维长度在4mm的条件下,匀度均方差较小,即纸张匀度较好;当碳纤维含量在5%,并且施加相同电压的条件下,成纸功率密度基本都维持在300~400W/m~2的水平,纸张温度在30~45t℃温度区间,可以通过调节碳纤维含量,以达到不同电学要求的碳纤维纸张。
Undertake carbon fiber paper preparation and electrical properties of the study. The results show that the appropriate beating degree of plant fiber pulp is 45 ~ 50 ° SR in order to obtain carbon fiber paper with relatively good grain formation. When the carbon fiber content is 5%, the breakage index of carbon fiber paper is not less than 5k Pa · m ~ 2 / g, the tear index is more than 8.0m N · m ~ 2 / g, the rupture length is more than 6km, so the carbon fiber content of 5% is more appropriate; when the carbon fiber length is 4mm, When the carbon fiber content is 5% and the same voltage is applied, the power density of paper is basically maintained at the level of 300 ~ 400W / m ~ 2 and the paper temperature is 30 ~ 45 t ℃ temperature range, you can adjust the carbon fiber content to meet the different electrical requirements of carbon fiber paper.
