Influence of the tufting pattern on the formability of tufted multi-layered preforms

As a relatively novel technique, tufting is recently used to provide through-thickness reinforcement of a traditional 2D multi-layered preform, thus improving its resistance to delamination in the final part. In order to optimize the manufacturing process of the composite preforms reinforced by tufting, the studies of the forming behaviour of these tufted preforms are quite necessary, in particular, the influence of the tufting pattern. The...
