This data article presents the AE measured from composite panels with a single stiffener during compression-compression fatigue loading until end-of-life. Different kinds of damage have occurred, especially induced by defects such as a pre-embedded disbond and impact at different locations. Low-level AE features were extracted from AE waveforms, including amplitude, rise time, duration, energy, counts, and RMS. Then, they were windowed according to different lengths (LW) and intervals (Int) in terms of the loading cycle. Moreover, diverse statistical features in time and frequency domains from each time window were extracted and are available. Both AE variables (low-level features) and statistical features can be utilized for research in prognostic and health management as well as composite structures. Ten different combinations of lengths (LW) and intervals (Int) were considered, including 100, 500, 1000, and 5000 cycles. Besides the AE low-level and statistical feature datasets, figures of the total number of events within each TW for different combinations of LW and Int are provided.
