Abstract In the present work, a novel entangled metallic wire material-polyurethane(EMWM-PU) composite was developed through the vacuum infiltration method with the entangled metallic wire material (EMWM) as the matrix and polyurethane as the reinforcement. By comparing the quasistatic compression properties of EMWM and EMWM-PU composites, it was found that the composites exhibited excellent energy consumption and stiffness properties due to the interfacial friction. The pipeline test platform was built, and the vibration acceleration level and insertion loss were used as evaluation indexes. In addition, the effects of EMWM density, excitation levels and preload on the vibration damping performance of the pipeline were studied in detail. The results showed that the EMWM-PU composites have excellent vibration reduction effect in the frequency band of 5—1 000 Hz, and the smaller of the matrix density and the larger the preload during installation, the better the vibration reduction effect. This study provides effective guidance for the design and application of EMWM composites.
