Abstract: As fiber-reinforced composite are widely used as alternative of conventional materials in the constructions of supersonic airplane, marine, automobile, the knowledge in damping of composites is becoming more important for controlling the noise and vibration in the structures. In recent years the research on composite damping mechanisms and prediction methods have received extensive attention. This paper reviews recent achievements in damping studies for fiber-reinforced composites at both the macro- and micro-mechanical levels. The effects of some important factors such as fiber/matrix interface, interlaminar stresses, and transverse shear deformation on specific damping capacity of composites are also summarized. Finally, improvement and optimization for damping are introduced, and some recommendations regarding future research are prospected.
