  Abstract

The most common working condition in the static seal connection system is load fluctuation. The failure mechanism of sealing material caused by load fluctuation is more complicated than that under static load. This work develops an experimental method to research mechanical property of short fiber reinforced rubber matrix sealing composites (SFRC). The damage behavior of creep and stress relaxation after different fatigue cycles is obtained. The microscopic defects are observed and analyzed by scanning electron microscope (SEM). The effects of different fatigue cycles on the damage of materials are found, and the damage modes of SFRC are determined. Based on macroscopic phenomena and microscopic mechanism, the parameters of new creep and stress relaxation models of SFRC after different fatigue cycles are determined, respectively. It can be found that the phenomenological model can well characterize fatigue behavior of SFRC.
