ABSTRACTThe tailoring of the sign and magnitude of the absolute thermoelectric power was achieved in structural composites by the choice of the reinforcing fibers and of the particulate filler between laminae. The resulting thermoelectric structural composites included continuous carbon fiber polymer-matrix composites and short fiber cement-matrix composites. In addition, it resulted in thermocouples in the form of structural composites. The fibers and interlaminar filler impacted the thermoelectric behavior in the longitudinal and through-thickness directions respectively.

Stability Frequency

Treat continuous carbon fiber with special technology, followed by pasting the electrode pole to it and in epoxy resin, a high resistance-strain sensitivity of polymer-matrix carbon fiber strain sensor can be achieved. Paste this element on the beam of fiber glass reinforced plastics, we tested its linearity、sensitivity、stability, frequency response etc. The results indicate that the sensitivity of this component is more than 400 as well as load frequency less than 10Hz. Its dynamic tracking performance is in relatively sound with no significant response lag.
