EVALUATION OF FATIGUE LIFE OF ADHESIVELY BONDED CFRP PIPE STEEL ROD JOINTS

In order to investigate a key parameter governing the fatigue strength of adhesive-bonded CFRP pipe/steel rod joints, a series of rotating b ending fatigue tests was carried out on the joints with different lap lengths and with different pipe thicknesses. Fatigue test data were di scussed on the basis of stress distributions in the adhesive layer det ermined by FEM analysis. The results indicated that the fatigue streng th of the joint mainly depended on the maximum tensile stress normal t o the adhesive/adherend interface at the lap end.
