“…An alternative approach to improve the ultimate strength of joints is to reinforce the bonded region with stitches [1][2][3][4][5][6][7][8][9], rods or pins [10][11][12][13][14][15][16][17][18]. Stitching with high strength fibrous yarns through the overlap region of a joint improves both the tensile strength (up to 40%) and fatigue performance (up to two orders of magnitude) [6][7][8][9].…”

“…Most of the studies (e.g., [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]) were focused on the benefits of z-pinned laminates such as improved delamination toughness, impact damage tolerance, and joint strength. Although these studies contributed to the clarification of the interaction between stitches and laminate, up to now, the effect of various stitching parameters on the fracture performance of lap joints has not been adequately understood.…”

Experimental Characterization of the Properties of Double-Lap Needled and Hybrid Joints of Carbon/Epoxy Composites

et al. 2015

The effect of through-thickness reinforcement by thin 1 mm steel needles (z-pins) on the static tensile strength of double-lap joints of a carbon/epoxy composite was investigated. Two types of joints—z-pinned and hybrid (including glued ones)—were considered. The joints were reinforced in the overlap region with 9, 25, or 36 z-pins. Comparing mechanical properties of the double-lap joints with the corresponding characteristics of their unpinned counterparts, the z-pins were found to be highly effective: the strength and stiffness of the pinned joints increased up to 300% and 280%, respectively. These improvements were due to a transition in the failure mechanism from debonding of the joint in the absence of z-pins to pullout or shear rupture of z-pins or to the tensile failure of laminate adherends, depending on the volume content of the pins.
