Three-dimensional (3D) fabrics as one type of multilayered reinforcement become more and more popular, due to its better performance in thickness direction of part. Recently, tufting technique is developed and applied to manufacture the 3D textile composite reinforcements. The present study investigates the influence of tufting density and tufting pattern on the formability behaviours and forming defects. High tufting density can reduce the size of wrinkles significantly. The tufting pattern influences slightly on the wrinkling phenomenon. However, square spiral pattern can eliminate buckles of tufting yarns at four corners, especially in the deep-draw forming.
