Paper Abstract
Good adhesive bond between the laminates is extremely important for the shear strength of adhesively bonded poly-rubber-steel concetric cylinders used as marine shaft vibration reducers (SVR). The SVR are inspected nondestructively by using a high-speed PC-based transmission ultrasonic C-scan system capable of scanning and producing images. Transmission of ultrasound at frequencies between 5-20 MHz and time-of-flight variations of these signals through these multilayered structures is used to determine the disbonds at the interfaces. Two- and three-dimensional images are generated and analyzed statistically to quantify the areas of disbond. Mathematical models for the propagation of ultrasound through such a layered structure are applied for the interpretation of these images.
