MATERIALS CHARACTERISATION AND STRUCTURAL HEALTH MONITORING OF COMPOSITE STRUCTURES USING ULTRASONIC GUIDED WAVE

摘要

The ultrasonic guided waves are employed to develop a sensor system that can be permanently attached to the aerospace composite components for the purpose of continuous or intermittent monitoring of the health of the structure. The system is capable of detecting impact and dis-bond damages that occur during the service of the aircraft. The sensor patch design, sensor reliability, low footprint sensor electronics, data processing and evaluation automation, wireless communication, energy requirements, etc. will be discussed in this paper.
