Multiscale modeling of hybrid structural composites with integrated damping features

The aim of this work is to propose a design approach for a multifunctional hybrid composite material that integrates high damping performances while withstanding the required structural features. Hybrid composite consists in a three phases composite where a viscoelastic material is added to the conventional structural long fibers/polymeric matrix laminate. Design addresses the problem of integrating the viscoelastic material within the laminate architecture to exploit its maximum damping efficiency. Key aspect is the definition of a viscoelastic multiscale model starting from the constituents to the lamina, and further to the hybrid laminate properbes.
