Macro- and mesoscopic mechanical properties of complex fabric rubber composite under different temperatures

In this paper, the mechanical properties of complex fabric rubber composite under different temperatures are studied based on the macro- and mesoscopic structural characterization. First, the normal stresses of the inner reticulated fabric rubber composite are determined based on the anisotropic hyperelastic constitutive model and the corresponding hyperelastic material parameters under different temperatures are obtained using the normal stress equations to fit the experimental results. Second, the representative volume element of surface fabric rubber composite is established and the corresponding homogenization anisotropic constitutive parameters are obtained numerically under different temperatures. Finally, the mechanical properties of complex fabric rubber composite under different temperatures are characterized by means of numerical simulation and experiment. This paper provides an effective method to analyze the mechanical properties of complex fabric rubber composite under different temperatures, which has important guiding significance for the design of advanced fabric rubber composite.
