Abstract
A wide-band acoustic spectroscopy employing a laser sound source was u sed for measuring the ultrasonic attenuation in samples of glass-fiber composites in the frequency range from 1 to 20 MHz. Resonant peaks of attenuation due to the periodical structure of the composite were fou nd. A transformation of the ultrasonic attenuation spectra accompanyin g changes in the sample structure due to microplastic fatigue was obse rved.
