Measurement of Conductivity of Carbon Fibers at Microwave Frequencies

Popis výsledku v původním jazyce

The paper presents results of measurements conductivity of carbon fibers from DC to 13 GHz. The measurements were performed on the microstrip measurement line, where a section of the line is made from a flat tow of carbon fibers. Physical conductivity ofcarbon fibers is derived from the measured value of S21 of the section of microstrip line in two steps. First, a tow of fibers is replaced by a homogenous material having an unknown effective conductivity. Then S21 of the section of the microstrip linehaving metallization made from the effective media is analyzed by 3D fullwave simulation program for a range of effective conductivities. The actual effective conductivity is found iteratively to match the measured and simulated S21 coefficients. Second,S21 of the planar slab having the effective conductivity obtained in the first step is calculated analytically. Then the slab is assumed to have a real microstructure with densely packed carbon fibers. The physical conductivity of the fi
