Robotic Tufting and Z-Pinning

Robotic Tufting and Z-Pinning

Composites are the materials of choice for aerospace applications due to their excellent mechanical and other properties. However due to their laminar construction they have poor out-of-plane characteristics. Tufting is a technique wherein a reinforcement in the form of twisted yarn is inserted into composite layers to improve the out-of-plane properties like delamination resistance and delamination growth of composite structures. This would also help to improve the interface joint strength in cocured composites. Z-pinning is a through-thickness reinforcement technology, which increases delamination resistance, post impact toughness and joint strength of composites. Robot controlled automated Z-pinning/Tufting head aids in orthogonal insertion of Z-pins in the composite prepreg material or  twisted into composite layers.
