C-scan dataset of impact damages on composite coupons and laminates. This dataset contains ultrasonic full-waveform Phased Array (PA) data that were acquired during the experimental assessment of impact damages on composite coupons and laminate conducted by Cranfield 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 on composite coupons is acquired by using 5MHz wheel probe2 Phased Array (PA) the transducer is in raw CSV format and processed C-scan in PNG image format. The 10MHz PA transducer and novel elastomer wedge which is a part of PA module developed at Cranfield and novel mist couplant delivery are used for scanning both coupons and laminates and raw data is in CSV format and processed data in TIFF image format. Also, a document on information about material and layup of coupons and laminate is also included. The data were used in the deliverable D2.3, D2.4 and D7.1 and D7.2.
