Research progress in fiber reinforced polymer damping composites

Fiber reinforced polymer composites are widely used in aerospace, automotive, shipbuilding, rail transportation, and other fields. With the development of lightweight high-speed aerospace and precision instrument automation, vibration problems are increasingly prominent, and it is necessary to develop new structural-damping composites with high mechanical properties and high vibration damping performance. Based on the research of fiber reinforced polymer damping composites in the past decade, the damping mechanism of the material was described, and the influence of polymer matrix, reinforced fiber, interface and other factors on the damping performance of fiber reinforced polymer composites was summarized, providing a reference for further developing fiber reinforced polymer composites with the required damping performance. Finally, the existing problems and development directions of fiber reinforced polymer damping composites are discussed, such as the development of new materials, new methods,new mechanisms, the co-optimization of damping properties of composite materials and mechanical/ technological properties, and the corresponding relationship between the damping properties of components, materials and structures.
