    Characteristics of fatigue behavior in GFRP pipes under cyclic compressive loading was investigated at both room and cryogenic temperature. Experimental work was carried out to clarify an effect of the temperature rise of the specimen on the dynamic mechanical properties for both environmental conditions. It was found that surface temperature of the specimen rose in the room temperature tests and that the variation of the temperature was dependent on the frequency of the fatigue test. Although, there was not a large change is temperature at 77 K. Variation in the stiffness and the energy dissipation caused by the static friction were investigated experimentally. And a viscoelastic-plastic model based on the Damorheology was also used to describe the hysteresis loops and separate the energy dissipation into the each of static frictional element and viscous element. The variation of the static frictional element with cyclic loading was a good agreement with the experimental data.
