FSP sensor data

The database of 27 normal and defected composite laminates (in two sets of samples) including normal and defected composites fabricated are shown in Table 1. The classification is obtained by visual inspection. The sensor data is made available in three folders. The first is “Sensor data Set1 and Set2” which contains the 54 .csv files containing the raw time series signals generated by the NI data acquisition system including vibration, current and force (X, Y, Z) signal values synchronized in 0 to 5 V for each of the 27 samples in two different sets on which FSP is performed. Second folder named as “Features extracted” contains the time domain and frequency domain features extracted using standard libraries. Third folder contains the “L27 sensor-data” which includes the excel file of all 27 samples prepared and their respective mean mode and median of sensor data for each sample which are further labelled of the defect condition.表1展示了一套包含27件正常与带缺陷复合层板的数据库，该数据库分为两组样本，涵盖已制备完成的正常复合材料与缺陷复合材料。该数据集的样本分类通过目视检验完成。 传感器数据以三个文件夹形式提供： 第一个文件夹为"Sensor data Set1 and Set2"，内含54个.csv格式文件，存储由NI数据采集系统生成的原始时间序列信号。这些信号涵盖振动、电流及力（X、Y、Z）三类信号值，同步电压范围为0~5V，对应两组中所有执行了FSP的27个样本。 第二个文件夹命名为"Features extracted"，存储通过标准库提取得到的时域特征与频域特征。 第三个文件夹为"L27 sensor-data"，内含针对全部27个已制备样本的Excel文件；该文件记录了每个样本的传感器数据均值、众数与中位数，并对其缺陷状态进行了标注。
