Here, dynamic responses of a square sandwich panel composed of T700 carbon fiber laminated face sheets and aluminum foam core were studied with tests. The square sandwich panel with four edges clamped was impacted by an aluminum foam projectile. A high speed-video camera and a laser displacement transducer were used to record the velocity of the foam projectile, the process of the foam projectile impacting the panel’s front face sheet and the displacement time history curve of the central point on its back face sheet. The effects of loading time momentum and core layer relative density on the panel’s impact responses were studied to get deformations and failure modes of the panel. At the same time, dynamic responses of the carbon fiber composite sandwich panel with aluminum foam core under impact loading were simulated and analyzed with the finite element software ABAQUS. The results showed that composite face-sheets’ thickness and layering mode, foam core’s thickness and relative density, and foam projectile’s length, velocity and relative density etc. have obvious influences on impact responses of the sandwich panel.
