Data from: Evaluation of delamination propagation speed by means of high speed infrared thermography during low velocity impact tests

This dataset comprises a collection of experimental observations using high temporal resolution infrared thermography focused on delamination propagation in cross-ply laminates laminated T700GC/M21 composite materials. The dataset is a supplement to the research article titled "Evaluation of Delamination Propagation Speed Using High-Speed Infrared Thermography in Low-Velocity Impact Tests." It contains the raw apparent temperature images taken at varying impact velocities (0.94 m/s, 1.22 m/s, and 1.73 m/s) and the processed images.
