Effects of Corrosion Behavior on Failure of Co-Cured Single Lap Joints Subjected to Cyclic Tensile Loads

피로하중이 가해지는 외면겹치기 동시경화조인트의 파괴에 미치는 부식의 영향

  • Published : 2010.03.01


Co-cured single lap joints under cyclic tensile loads fail initially at the tip of the interface corner between the two adherents. The failure mechanism is complex because it is related to corrosion fatigue. Corrosion behavior at the interface affects the failure of the joints because corrosion deteriorates fatigue resistance. In this study, we clarified the cause of interfacial corrosion in co-cured single lap joints under cyclic tensile loads. The failure mechanism was also analyzed by observing the failed surfaces of specimens and the stress distribution along the interface. The surface roughness at the interface and the stacking sequence of the composite adherent were examined to investigate their effects on failure of the joint.
