Resumo

The damping characteristics of hybrid composite materials reinforced with elastic spherical and fibrous inclusions with viscoelastic coatings are studied. It is shown that in composites with particles morphology, the effect of significant increase of dissipation loss can be realized, andᵇ the effective composite properties loss can exceed the dissipation loss of viscoelastic coatings more than twenty times. The analytical estimations for optimal parameters of hybrid composite materials are proposed. The influence of possible imperfections in composite structure on their effective dissipation properties are analyzed.
