Abstract With the continuous development of composite materials, it has been widely used in aerospace and other fields. In order to meet the further development needs of various fields, the requirements for the mechanical properties of composite materials have gradually increased. In this paper, the damage of carbon fiber foam sandwich structure(Material designation:W-3021FF/H60)under different sandwich thickness and impact energy is studied. Ultrasonic C scanning is used to measure the depth and area of impact damage area. Finally, the impact of impact energy and foam core thickness on impact damage is analyzed by test and test results. The results show that the impact damage depth and area of foam sandwich structure is positively related to the impact energy, and with the increase of impact energy, the growth rate of damage depth and area changed; the larger the thickness of the foam core is, the span-direction guiding energy for impact energy, the larger the damage area and the smaller the damage depth.
