Investigation of Fatigue Performance of 3D Tufted Composites

Over the past decade, the use of reinforced composites in aerospace applications has been increased and this type of composites is now applied in a most of load-bearing structural composite structures. Fatigue life and behavior of new developed reinforced composite such as tufted composites have been treated as a design limiting feature. This paper focused on the fatigue behavior of tufted composite by investigation of S-N curve under different tensile stress levels and damage progression in samples. The failure modes of the composite specimen under the fatigue loading conditions were analyzed
