The paper investigates the influence of different interlayer angles on dynamic behavior of composite sandwich structure subjected to low-velocity impact. The composite sandwich structure is composed of CFRP/epoxy laminates and Nomex honeycomb core. Seven finite element models with seven different interlayer angles, from [0°/0°/0°/Honeycomb/0°/0°/0°] to [0°/90°/0°/Honeycomb/0°/90°/0°], of composite sandwich are implemented by ABAQUS/Explicit. The damage mechanism for composite laminate is applied with 3D Hashin’s damage by VUMAT, while the honeycomb is based on traction separation laws. The modeling results show that as interlayer angle increases, the indent area is decreasing, but the rate of decrease becomes slower. Meanwhile, the energy absorption is increasing with the higher interlayer angle. From mentioned above, it can be concluded that the interlayer angle has an effect on the impact behavior of composite, and the bigger interlayer angle will result in better impact resistance.
