The measurements possibilities of acoustic damping in composite materials

Abstract

With the wider use of composite materials in aviation, the observation of their quality during exploitation is becoming more topical. We are of the opinion that acoustic technologies of all in one control offer us promising possibilities to observe and research the characteristics and parameters of composite materials. The purpose of this paper is to discuss some accepted ways of tuning the damping of the acoustic signals in non‐homogeneous environments for research of composite materials.
