Abstract:
An object is to provide a delamination inspection method and a delamination inspection apparatus capable of easily and distinctly detecting an inter-layer delamination of a laminated body even when an obstacle such as a reinforcing plate is present on a part to be inspected, and capable of inspecting a wide inspection area in a short time. The apparatus includes: a transmission probe  2 a  that causes an ultrasonic wave to enter a laminated body  10  at a predetermined refraction angle θ; a reception probe  2 b  that receives a propagation wave having propagated while having been repeatedly reflected by interfaces of a plurality of members; and a probe holding means that holds the transmission probe  2 a  and the reception probe  2 b  with a predetermined interval L therebetween. A propagation wave having propagated through a sound part is received, and a detection length over which the echo height of the received propagation wave is detected as being equal to or greater than a predetermined value is obtained as a reference detection length. The propagation wave having propagated through an inspection target part E is received, and a detection length over which the echo height of the received propagation wave is detected as being equal to or greater than the predetermined value is measured. The measured detection length is compared with the reference detection length to inspect whether or not an inter-layer delamination D is present in the inspection target part E.

Claim (Index 5):
The delamination inspection method for the laminated body according to  claim 1 , wherein\n the sensor further includes a first scanning means configured to cause the transmission probe and the reception probe to scan along a first scanning direction, and a second scanning means configured to scan along a second scanning direction intersecting the first scanning direction, and the position of the inter-layer delamination is specified through the scanning of the first scanning means and the second scanning means.
