| Abstract: | This study investigates the impact of localization on a carbon fiber-reinforced polymer (CFRP) composite plate, considering the operating temperature of the composite structure. A multiplexed fiber Bragg grating (FBG) sensor, utilizing a cross-correlation-based impact localization algorithm, was employed for this purpose. This algorithm primarily depends on the shape of the impact response wavelength and is minimally affected by temperature variations. The study validates the effectiveness of the cross-correlation-based impact location detection technique with temperature compensation within the operational temperature range of composite structures. Results demonstrated that the algorithm successfully estimated the impact location for each of the 10 impact points at temperatures of −20, 0, 20, and 40 °C. Out of 40 impact points, 33 were accurately estimated under the given temperatures, with a total average error of 3.30 mm, which is significantly lower than the predefined grid size of 80 mm, equating to an error rate of 4.13%. Therefore, the cross-correlation-based impact localization algorithm has proven to be a promising tool for impact monitoring systems in composite structures under various temperature conditions.
