Ultrasonic detection methods for mechanical characterization and damage diagnosis of advanced composite materials: A review

Advanced composite materials are prone to various types of damage during - manufacturing and long-time service. Ultrasonic detection methods have been widely employed to detect damage because of their high accuracy and reliability. This study gives a comprehensive review of the ultrasonic detection methods for damage diagnosis and assessment of advanced composite materials. Firstly, the typical damage types and their effects on composite materials are introduced. Ultrasonic measurement methods for determining the parameters of composite materials are reviewed to enhance damage detection accuracy. In addition, acoustic models, detection techniques, and imaging methods based on ultrasonic bulk wave or guided wave detection technologies are discussed. Further, the damage diagnosis of composite materials, criteria for damage assessment, and analytical methods for predicting the remaining service life of damaged composite materials are reviewed in detail. Finally, insights into the application prospects of advanced composite materials, including the acoustic modeling of different composites, integration of multiple ultrasonic testing technologies, development of fast damage monitoring systems, establishment of damage diagnosis criteria, and lifespan prediction of damaged composites, are provided.
