“…It is found that each failure mode has a corresponding frequency response range. For the frequency range of matrix crack, delamination, and fiber fracture, the frequency ranges are validated from a number of our tests, which is in accordance with the experiments performed in [22][23][24][25][26]. For example, Sause et al [16] confirmed these frequency ranges through numerical study, which found that the frequency ranges for matrix crack, delamination, and fiber fracture are 100-300 kHz, 300-400 kHz, and 400-700 kHz.…”

“…Gutkin et al [18] used competitive neural networks to analyze the CFRP and found that the frequency ranges for matrix crack, delamination, and fiber fracture are 0-150 kHz, 300-400 kHz, and 400-700 kHz. Huang et al [23] used AE signal to analyze pure resin matrix with matrix crack, resin matrix within a carbon fiber tow and precuts delamination specimen and found that the frequency ranges are within 58-185 kHz, 190-290 kHz, and 405-455 kHz. In summary, all of the above experiments show that the frequency ranges of matrix crack, delamination, and fiber fracture are within 100-300 kHz, 400-550 kHz, and 600-750 kHz.…”

“…In recent years, AE technology has been widely used to identify and distinguish different damage modes in the field of composite laminates. Some researchers have classified the damage of composite laminates during the loading process into several modes, such as matrix fracture, fiber breakage, fiber–matrix interface debonding, and delamination [ 25 , 26 , 27 ].…”

“…However, distinguishing the specific frequency ranges corresponding to various fracture modes based on testing samples with different geometric sizes did not take into consideration the fact that frequency is connected with size [ 19 , 25 , 28 ]. In addition, samples of a same geometrical size composed of a single material, such as a fiber bundle, do not account for friction between fibers, which changes the sample frequency [ 19 , 26 , 27 , 28 ].…”
