Abstract The stitched/unstitched foam sandwich structures with a layer of [45°/-45°/0°/90°]_2s were prepared by the vacuum assisted transfer molding (VARTM) process. Subsequently, five repeated low-velocity impact experiments with different falling hammer impact times were carried out on them under the impact energy of 15 J, and then the invisible damage inside the fiber panel after impact was characterized by Micro-CT scanning, thus revealing the internal damage mechanism. The results show that the damage patterns of foam sandwich composite materials mainly include delamination damage, matrix cracking and fiber fracture. After the first five impacts, the foam sandwich structure composite material mainly produces delamination damage and matrix cracking, and the fiber fracture only appeares at the impact position; with the increase in the number of impacts, fiber fractures become more serious. The main damage pattern of the interlayer damage of the panel is different from the impact surface to the inside of the material; the damage area is increasing and the damage area of the 7th to 8th interlayer delamination close to the foam is the largest. In addition, the stitch resin column can effectively improve the impact resistance of the foam sandwich structure. Compared with unstitched, the residual max impact force of the stitched foam sandwich composite material with the same impact times can be increased by 33.4%—48.1%. The relationship curve between the number of impacts and the depth of the pit under 15 J energy is obtained, and the corresponding mathematical formula is fitted. With the inflection point position of the curve combined, the damage pattern of composite material can be predicted.
