Abstract
The through-thickness thermoelectric behavior of continuous carbon fiber epoxy-matrix composites is greatly improved by adding tellurium particles (13vol.%), bismuth telluride particles (2vol.%) and carbon black (2vol.%). The thermoelectric power is increased from 8 to 163μV/K, the electrical resistivity is decreased from 0.17 to 0.02.Ω.cm, the thermal conductivity is decreased from 1.31 to 0.51W/m.K, and the dimensionless thermoelectric figure of merit ZT at 70°C is increased from 9×10−6 to 9×10−2. Tellurium increases the thermoelectric power greatly. Bismuth telluride decreases the electrical resistivity and thermal conductivity. Carbon black decreases the electrical resistivity.
