Abstract

In a component having vibration-damping properties, a mixture for manufacturing the component, and a method of manufacturing such a component, the component has granular and/or grain- and/or flake-shaped piezoelectric particles which are embedded in a polymer matrix in a proportion of at least 10 volume %. In order to improve the damping effect, at least some of the piezoelectric particles have a polarization which is different from zero.
