The purpose of the paper is to analyze the damping characteristics of several advanced fibre-reinforced composites, and ulteriorly optimize the damping performance of a composite structure. Numerical modelling of the damping was developed considering the finite element method based on the modal strain energy. The modal damping characteristics of the fibre-reinforced composites were evaluated, including the modal frequencies, modal shapes and modal loss factors. The damping performances of different fibre-reinforced composites were compared. Furthermore, the damping performance of a laminated composite structure was optimized by considering the effects of different lay-up sequences and layer orientations. An optimum design scheme of the composite structure was presented. [ABSTRACT FROM AUTHOR]
