In this paper, the dynamic response characteristics of aluminium honeycomb sandwich panels under repeated rigid wedge impacts and ice wedge impacts were experimentally studied by using the horizontal impact test apparatus. The impact force-displacement curves and the structural deformation properties were obtained. Results show that with the increase of collision numbers, the peak value of collision force increases continuously, the contact time decreases significantly, the local indentation and global bending deformation of face sheet increase gradually, the compressive deformations of the honeycomb cores enlarge gradually and finally the densification phenomenon appears. Due to the ice fragmentation phenomenon in the collision process, the contact area under ice wedge impact increases. Compared with rigid wedge impact, the midpoint permanent deflection of top facesheet under ice wedge impact is smaller, but the local damage area is obviously larger. With the increase of collision numbers, the plastic accumulated deformation of honeycomb sandwich panel evolves from a plastic hinge line to an elliptic plastic zone.
