Study on dynamic properties of metal entangled structure/silicone rubber interpenetrating composite

Microporous metal entangled structure (MES) can reduce various hazards caused by vibration due to its good damping energy dissipation. However, its bearing capacity is weak and cannot realize the multifunctional characteristics of high damping and high stiffness. In this work, a kind of interpenetrating metal entangled structure/silicone rubber composite (MES-SRC) is developed, which is composed of MES as the skeleton and the silicone rubber as the matrix. The dynamic mechanical tests of MES-SRC, MES, and silicone rubber are conducted, and their dynamic properties, including bearing capacity, damping energy dissipation, and damping, are quantitatively characterized. The test results show that the bearing capacity and damping energy dissipation of MES-SRC are higher. Through the analysis of the mesostructure of MES-SRC, the damping energy dissipation mechanism of MS-SRC is studied. The effects of vibration conditions and process parameters of MES on dynamic properties of MES-SRC are studied, and the reasons for the effects are explained from the mesostructure.

Automated summary

In this study, a new type of interpenetrating metal entangled structure/silicone rubber composite (MES-SRC) is developed. Through dynamic mechanical tests and analysis, it is found that MES-SRC has higher bearing capacity and damping energy dissipation.
