Data underlying the publication: Acoustic Emission Approach for Identifying Fracture Mechanisms in Composite Bonded Joints: A Study on Varying Substrate’s Stacking Sequence

The dataset shared here contains the acoustic emission raw data of quasi-static mode I crack propagation tests in secondary composite adhesively bonded joints. Five adhesively bonded tailored composites with different stacking sequences were manufactured and tested. The specimens underwent several damage mechanisms, including cohesive failure, delamination, fibre breaking and fibre-matrix debonding.The dataset is divided into different folders, with the specimen identification described here: https://doi.org/10.1016/j.tafmec.2024.104490. Moreover, two types of files will be saved in each folder: .tradb (transient waveforms recorded during the tests) and .pridb (file that includes all the parameters recorded for each waveform).An additional folder named Load versus Displacement contains the experimental curves taken from the quasi-static mode I test.本数据集包含二级复合粘接接头准静态I型裂纹扩展试验的声发射原始数据。研究团队制备并测试了五种具备不同铺层序列的定制复合粘接试样。这些试样在试验过程中经历了多种损伤机制，包括内聚失效、分层、纤维断裂以及纤维-基体脱粘。本数据集按不同文件夹进行划分，试样标识说明详见：https://doi.org/10.1016/j.tafmec.2024.104490。此外，每个文件夹内将存储两类文件：.tradb（试验过程中记录的瞬态波形）与.pridb（包含各波形全部记录参数的文件）。另有一个名为「载荷-位移」的文件夹，其中存放了准静态I型试验获取的实验曲线。
