ACOUSTIC EMISSION DURING TENSILE TESTING OF COMPOSITE MATERIALS

Popis výsledku v původním jazyce

This paper deals with possibilities of acoustic emission method utilization as an online surveillance tool for improvement of identification of structural damage onset in composite materials. With employment of AE method we are able to localize the degraded areas in stressed components and subsequently estimate the extent of degradation. In experimental part the piezoelectric sensor was employed for continuous record of emission signals, continuous processing and analysis of measured data and monitoring of stressed material feedback on applied mechanical load in real time. Partial results from distinctive areas of conducted research were implemented in this method, especially detection of emission signals and analysis of recorded signals in both frequency and temporal zones. Samples were reinforcement of 6 layers aramide-carbon weave 0/90° of specific mass 180 g/m2. In total 7 samples were tested in monoaxial tension on universal testing apparatus ZDM 5/51 with acoustic emission measurement recording in course of testing.
