采用气相金属化方法对微卷曲碳纤维进行金属化处理，制备了SiC和TiC微卷曲纤维，充分保留了源卷曲碳纤维的卷曲形态，并对其制备条件和体电阻率进行了测试。sic1.0线圈在1400℃下保温2 h， tic1.0线圈在1100 ~ 1200℃下保温1.5 h。卷曲TiC纤维的体积电阻率随体积密度的增加而急剧下降，在1.4 g cm−3时为10−2S−1cm。
Micro-coiled fibres of SiC and TiC were prepared by the vapour phase metallizing of micro-coiled carbon fibres with full preservation of the coiling morphology of the source coiled carbon fibres, and their preparation conditions and bulk electrical resistivity were examined. The SiC1,0coils were obtained at 1400 °C for 2 h, and TiC1.0coils were obtained at 1100–1200 °C for 1.5 h. The bulk resistivity of the coiled TiC fibres sharply decreased with the bulk density and was 10−2S−1cm at 1.4 g cm−3.
