Thin-walled structures made of CFRPs are widely used in engineering field.As strength of CFRPs is reduced by internal damages,the detection of the damages by NDT is important issue.Lamb-wave tomography is one of the methods that can obtain the image faster than traditional ultrasonic pulse-echo method.However,image construction method is still under discussion by many researchers and there is no established method to construct the images especially for anisotropic thin materials such as CFRP plates.Furthermore,Lamb-wave tomography method requires attaching a lot of sensors around inspection area in general.This is another reason that Lamb-wave tomography does not widely utilize to detect damages in CFRP structures in thisstage.
