The Acoustic Black Hole （ABH） as a new wave control technology achieves wave energy aggregation and dissipation by cutting structure thickness， exhibiting a good application prospect in vibration and noise reduction and energy recovery of engineering structures. Carbon Fiber Reinforced Plastics （CFRP） is widely used in aeronautical engineering because of its light weight， high specific strength， and specific modulus. To investigate the ABH effect of composite structures， we use the finite element method and verify the existence of energy aggregation characteristic of carbon fiber composite sheet structures embedded with ABH （CFRP-ABH）， and further investigate the effect of ply angles on this characteristic. In addition， the dynamic characteristics of CFRP-ABH structures are analyzed through simulation calculation and experimental tests. The results show that the vibration level of the CFRP-ABH structure is 5-18 dB lower than that of the uniform thickness plate in the frequency range of 200-3000 Hz， displaying excellent broadband vibration reduction performance.
