C-scan dataset of impact damages on final demonstrator panel. This dataset contains ultrasonic full-waveform Phased Array (PA) data that was acquired during the experimental assessment of impact damages on final demonstrator panel conducted by Cranfield at Upatras AML lab in the context of project CompInnova: An Advanced Methodology for the Inspection and Quantification of Damage on Aerospace Composites and Metals using an Innovative Approach (H2020 FET OPEN, Grant Agreement No. 665238). The C-scan data are in raw CSV format and processed C-scan images in Tiff image format using algorithms developed at Cranfield for processing the raw CSV format. Also, a document on how to visualise raw data files in MS excel is also included. This C-scan data is acquired on the curved stiffened composite panel by using 10 MHz Phased Array (PA) transducer which is a part of PA module developed at Cranfield involving a novel elastomer wedge and novel mist couplant delivery for uniform distribution of couplant. The data were used in the deliverable D7.3.
