Visible Ultrasonic Nondestructive Testing Methods for Composite Honeycomb Sandwich Structure

Defects and structure details of composite honeycomb sandwich structure can be visualized by using ultrasonic imaging methods based on A-,B-,and C-Scan.Ultrasonic imaging provides the opportunities to see the bonding qualities of honeycomb sandwich structure.The research in this paper can be employed to evaluate the production process qualities of honeycomb core constructional element both in lab and in-service.
