The strain gauge, a thermocouple and the PVDF (polyvinylidene fluoride) piezoelectric thin film are embedded in Glass-Epoxy 2-D woven composite laminates as health monitoring technologies. The results show: Before the fatigue damage, the woven composite present the temperature rise; a thermocouple is better way to detect temperature.
