Characterizing the Damage State of Composite Laminates VIA the Acousto-Ultrasonic Technique

Acoustical and Dynamic Mechanical Characterization of Fiber-Matrix Interface Bonds in Ceramic Composites

“…Because the technique measures the response of the material to acoustic stresses in directions which lie in the laminate plane [5], it is potentially capable of characterizing the fiber-matrix bond. The name of the technique derives from the fact that it is basically a hybrid between ultrasonics and acoustic emission.…”
