- Abstract
- The analysis of the processing of acoustic emission (AE) information during static loading of CFRP specimens with preliminary impact damage is presented. The AE signals were registered by two Fabry-Perot fiber-optic sensors and two piezoelectric sensors combined antenna. Samples with installed sensors were statically loaded until fracture at a temperature of + 20 оC. Defects were located in real time mode. Wavelet transform was applied for processing of the information accounting the energy and frequency characteristics of the AE signals. The analysis of their main informative parameters (amplitude, frequency, structural coefficient, MARSE) was carried out. This made it possible to define the type of destruction (matrix, fiber, delamination) of the sample material.
