摘要：

In order to study the effect of stitch on the low-velocity impactresistance of foam sandwich composites. In this paper, three types of unstitched, through- thickness stitched, and stitched impact surface fiber sheet carbon fiber foam sandwich composite panels were studied. The impact test of 10J energy was carried out by drop hammer impact tester.Damage detection of the foam sandwich composite panels after impact was carried out by immersed ultrasonic scanning imaging system, and the damage of the different depth carbon fiber layers in the foam sandwich composite panels was obtained. The finite element simulation of the three types of foam sandwich composite panels was carried out by ABAQUS finite element software, the response of low-velocity impact and the damage of the panel was obtained. The results show that the stitched will make the damage of the ply uniform, which can greatly improve the integrity of the laminates so that the convergence between the layers is more closely. Under the small impact energy, the full thickness stitched and stitched the impact surface fiber panel can inhibit the damage of the layer, and the effect of inhibiting the delamination is not much different, and the layers near the impact surface are more likely to induce delamination damage. © 2018, Editorial Board of Polymer Materials Science & Engineering.
