Abstract
Micro-coiled fibres of SiC and TiC were prepared by the vapour phase m etallizing of micro-coiled carbon fibres with full preservation of the coiling morphology of the source coiled carbon fibres, and their prep aration conditions and bulk electrical resistivity were examined. The SiC1,0 coils were obtained at 1400 degrees C for 2 h, and TiC1.0 coils were obtained at 1100-1200 degrees C for 1.5 h. The bulk resistivity of the coiled TiC fibres sharply decreased with the bulk density and w as 10(-2) S-1 cm at 1.4 g cm(-3).
