The tensile fatigue tests as well as tensile constant elongation-rate (CER) tests for GFRP/metal conical shaped joint, GFRP/metal adhesive joint, and GFRP/metal bolted joint are carried out under various loading rates and temperatures. The tensile fatigue strength as well as the CER strength for these three GFRP joints depends clearly on time and temperature. The same time-temperature superposition principle holds for CER and fatigue strengths. Therefore, the master curves of fatigue strength for three GFRP joints can be obtained. It is clarified from these master curves that the time-temperature dependent fatigue strength of each GFRP joint shows very characteristic behavior.
