Process on the research of structure-damping composites

A huge challenge was presented on mass reduction and noise reduction of the traditional structural material with development of aerospace vehicles toward high-speed, light mass and multi-function, application of the precise electronic equipment and improvement of comfort requirements. In recent years, with the rapid increase of fiber-reinforced composite materials in the application proportion in aerospace, development of the new structure-damping multifunctional materials with both high mechanical properties and high vibration damping performance has become one of the hot topics of research. The damping mechanism of structure-damping composites was described firstly, further the major domestic and international research results of structural damping composites were reviewed, and then its future development trends were discussed, including the development of new multi-purpose damping intercalation materials, the introduction of new damping mechanisms, the development of multi-level structure model and multi-scale simulation of mechanical properties and damping properties.
