- Abstract
- The control of the process of destruction of five samples of carbon fiber T700 under static loading with a preliminary applied point impact was carried out. Defects were located by the acoustic emission (AE) method, and the stress-strain state of the samples was determined using strain gauge. The main informative parameters of AE signals (location, amplitude, MARSE energy parameter, rise time of the leading edge, structural coefficient, frequency) recorded by an antenna consisting of piezo- and fiber-optic sensors and corresponding to the process of a nonlinear change in mechanical stress recorded by strain gauges were analyzed.
