Damage assessments in three dimensional(3D) textile composites subjected to mechanical loading can be performed by non-destructive and destructive techniques. This paper applies the two techniques to investigate the fracture behavior of 3D tufted textile composites. X-ray computed tomography as a non-destructive evaluation method is appropriate to detect damage locations and identify their progression in 3D textile composites. Destructive methods such as sectioning toward observing damage provide valuable information about damage patterns. The results of this research could be utilized to evaluate the initial cause of rupture in 3D tufted composites used in aerospace structures and analyze fracture modes and damage progression.
