Prediction of Fiberglass Rupture by Detected Acoustic Emission

Igor Grabec

Acoustic emission of fiberglass composite material during tensile loading is characterized experimentally by a set of records. Regularity of recorded data enables prediction of the sample rupture when approaching the critical loadings. For this purpose a new statistical method is formulated. The prediction is performed by comparing acoustic activity of tested and representative samples. Results of the prediction agree with the experimental data and confirm the hypothesis that acoustic emission detection provides a proper basis for a simple nondestructive testing of very complex fiberglass composite.
