Abstract
In this paper, applicability of an orthotropic hyperelastic model to fiber-reinforced rubber for sealing parts used in the electric power generator was shown. The fiber-reinforced rubbers are composite materials with rubber matrix reinforced by fibers. The mechanical properties are anisotropy that depends on directions, strength and woven pattern of reinforcing fibers. A 2-dimensional finite element simulation code for the orthotropic hyperelasticity was developed to estimate the mechanical characteristic of the fiber-reinforced rubber. Material constants of reinforcing fibers and rubber matrix were obtained by tensile and biaxial loading tests experimentally. From the results of numerical simulations, applicability of developed code to the fiber-reinforced rubber for the electric power generator was shown.
