摘要 研究了湿法造纸技术制备超薄碳纤维纸的工艺。采用的碳纤维长度为6mm,通过超声分散、原纸成型(纯碳纤维面密度为20g/m2)、树脂浸渍、定模热压、碳化等步骤制得超薄碳纤维纸。研究了5种树脂浸渍浓度条件下,碳纤维纸的各物性参数随热压温度的变化关系。热压后的碳纤维纸厚度达到0.085mm。4%~10%浸渍浓度下,超薄碳纤维纸的电阻率随热压温度升高而增大;电阻率随树脂残炭量与纤维量的比值增加而降低,且变化率逐渐减小;透气率随浸渍浓度的增加而减小,且变化率逐渐减缓。

Abstract: The preparation of ultra-thin carbon fiber paper by wet papermaking technology was studied.The carbon fiber length was 6mm,the ultra-thin carbon fiber paper was prepared through following steps:ultrasonic dispersion,raw paper forming (pure carbon fiber surface density 20g/m2),resin impregnation,hot pressing and carbonization.The relationship between the properties of five kinds of impregnated resin at different hot pressing temperatures were studied.The carbon fiber paper with thickness 0.085mm was obtained.The paper resistivity increased with the increasing of hot-pressing temperature.The resistivity decreased with the increase of resin residual carbon and the rate of change gradually decreased.the gas permeability decreased with the increase of immersion concentration and the rate of change also gradually decreased.
Key words:  ultra-thin carbon fiber paper    impregnation concentration    hot pressing temperature    resistivity    permeability
