Abstract

V zaključni nalogi je obravnavano obnašanje biokompozita z bazaltnimi dvoosno usmerjenimi vlakni. S pomočjo prilagojenega sistema Arcan smo pri treh obremenitvenih stanjih (natezna, strižna in kombinirana natezno-strižna obremenitev) dokazovali korelacije med signali akustične emisije in mehanizmi poškodb, ki so prisotne pri kompozitnih materialih. Z analizo parametrov signalov akustične emisije smo identificirali različne procese poškodb ter pokazali korelacije med parametroma AF, RA, strižnimi in nateznimi razpokami.

Secondary title:	Acoustic emission at composite loading
Secondary abstract:	In the final assignment, the behavior of a biocomposite with basalt biaxial fibers is discussed. Using a modified Arcan system, we investigated the correlations between acoustic emission signals and damage mechanisms present in composite materials under three loading conditions (tensile, shear, and combined tensile-shear loading). By analyzing the parameters of acoustic emission signals, we identified various damage processes and demonstrated correlations between the parameters AF, RA, shear cracks, and tensile cracks.
