Abstract In order to prevent the debonding failure between stiffener and skin of composite hat-stiffened panel, stitching technology was adopted to improve the pull-off performance of stiffener-skin interface. The fiber fabric was stitched with single-wire curved needle stitching equipment, and then cured by VARI (Vacuum assisted resin infusion technology) to prepare stitched hat-stiffened panel samples. The failure mechanism of interface and the influence of stitching parameters on interface bonding performance were researched by pull-off test and finite element numerical simulation. Results show that the peak load of stitched samples is significantly higher than that of unstitched ones. The pull-off bearing capacity increases first and then decreases with the increase of stitch density, which is up to 26.7% higher than that unstitched ones when stitch density (Note: stitch density means stitch distance (unit mm)× row spacing (unit mm), the same below) is 5×10. The pull-off bearing capacity increases with the increase of thread fineness, and increases by 39.7% when the thread fineness reaches to 1 500 D. When skin/stiffener thickness ratio is 2, the pull-off bearing capacity increases by 27.35%, which achieves the best stitching effect.
