Improving the Mechanical Properties of Composite-Metal Joints by Surfi-Sculpt

Wei Xiong Z-pin is an effective through-thickness reinforcement technology in improving interlaminar toughness, suppressing delamination. The use of z-pins is currently limited to several high performance composite structures: most notably Formula One racing cars and F/A-18 E/F aircraft.

However, limited understanding of the mechanical performance of z-pinned structures with impact damages hinders the application of z-pinned composites. This research aims to investigate the influences of z-pins on the impact damage resistance and damage tolerance of composite structures.
