Compared with traditional composites, interpenetrating phase composites (IPCs) consist of two phases which are each interconnected in three dimensions. The mechanical properties of IPCs are seriously determined by their various micro-structures. Therefore, it is very important to obtain a reasonable mechanical model to characterize IPCs based on their preparation technologies and realistic micro-structures. A routine is compiled to describe the spatial distributions of interpenetrating phases by solving the phase field equation. And a 3D random finite element (FE) model based on the phase field method is presented which can characterize the realistic microstructure of IPC. The main content of this paper is vibration damping properties of polymer-metal IPC cantilever beam, combined with theoretical analysis and FE analysis. Based on viscoelastic cantilever beam vibration theory, the theoretical prediction formula of loss factor and the natural frequency are deduced. The vibration behaviors of polymer-metal IPC are simulated, and the predictions accord well with experimental data.
