Improving the delamination fatigue resistance of composites by 3D woven metal and composite Z-filaments

Metallic and composite z-filaments have been reported as effective solutions for improving the interlaminar fatigue resistance of fibre-polymer laminates, which is important to many applications that demand high delamination fatigue endurance. Here, we examine the mechanisms of three different z-filaments made from metallic and fibre composite materials and to quantify their effectiveness in improving the modes I and II interlaminar fatigue...
