The method of fabricatingcomposites composed of a glass microfiber matrix andthe conductive nanofibers is proposed. The nanofibersincorporating single-walled carbon nanotubes (SWCNTs) and an organic material are spread over the surface of glass microfibers and in some areasbetween microfibers are coupled together into a branched network. The contributions of intra-CNT and inter-CNT conduction mechanismsin the composites with different contents of SWCNTs are evaluated from the analysis of their impedance spectra.The crossover between two conduction mechanisms is observed at a content of SWCNTs of about 0.1 wt. %.
