摘要：
Features of the destruction of fiberglass composite materials were considered. It was shown that the sources of acoustic-emission signals during their destruction are mainly matrix cracking and delayering and fracturing of fibers. Correlation of the parameters of continuous and discrete wavelet transforms was also determined for acoustic-emission signals that correspond to various mechanisms of the destruction of fiber-reinforced plastic.
