Abstract:In this study, the electrical resistive heating of the ZnO/woven carbon fiber composite on the interlaminar region was evaluated. In ZnO/woven carbon fiber composite laminates, the interlaminar region, composed of ZnO nanostructured arrays embedded on woven carbon fiber sheets, interacts with the thermoset vinyl ester resin. ZnO nanostructured arrays were formed into nanorods (NRs) using a hydrothermal process. To investigate the electrical resistive heating behavior of the interlaminar region, we analyzed the temperature profile as a function of time in three zones: a heating zone, a maximum temperature zone, and a cooling zone. Electrical resistive heating was effectively achieved in the interlaminar region due to multiple junctions formed between the intrinsic woven carbon fiber tows as well as among ZnO NRs. The contact resistance at the interlaminar region of ZnO/woven carbon fiber composite increased as the ZnO molar concentration increased from 10 to 110 mM. This is because the interlaminar interface combined with the high surface density of ZnO NRs inhibits electron transport into the woven carbon fibers. Following electrical resistive heating, the resistance decreased due to the increase in the density of free electrons at high temperatures.
