Article Synopsis
- Carbon fiber-reinforced plastic (CFRP) structures can suffer from hidden impact damage that significantly weakens their mechanical properties, highlighting the need for effective monitoring systems.
- This study developed a structural health monitoring (SHM) system using ultrasonic guided waves, generated by a broadband chirp signal from a piezoelectric actuator, to detect and evaluate impact damage in CFRP materials.
- The research showed a linear relationship between the size of impact damage and the maximum time-of-flight (ToF) delay for various CFRP plate types, indicating that this SHM technique can effectively quantify damage size and extent.
