Dry Coupling Ultrasonic Inspection of Bonded Airframe Structures

Abstract

COMPARED with rivets, bolts or other mechanical fasteners, the adhesive bonding of metallic and composite materials in airframe structural components produces higher strength, better fatigue resistance, and significant weight and cost reductions. Such structures are, however, only as good as the adhesive bonding. Dry coupling ultrasonic non‐destructive inspection, although a comparatively recent innovation, is already a proven and effective method of detecting disbonds. The technique is far less laborious and more reliable than any other so far devised for this purpose.
