In this paper fracture surface of the fatigue delamination have been investigated. Fatigue delamination tests were performed on the carbon/epoxy under different stress ratios. Samples were cut from the DCB specimens and analyzed in Laser Confocal Scanning Microscope. The analysis was used to measure the roughness values. Different fractographic features observed in the study are discussed.

Abstract


In this paper fracture surface of the fatigue delamination have been investigated. Fatigue delamination tests were performed on the carbon/epoxy under different stress ratios. Samples were cut from the DCB specimens and analyzed in Laser Confocal Scanning Microscope. The analysis was used to measure the roughness values. Different fractographic features observed in the study are discussed.
