摘要：
A new structual model was developed for the compressive analysis of 3D integrated sandwich composites by using the finite element software ANSYS. The influence of pile height, pile density and material elastic modulus of the 3D composites on the compressive properties was studied in detail, and the influence characterizations were analyzed and discussed too. The results show that the maximum value of the stress appears in the interface between pile and face-sheet when the 3D composites are subject under compressive loads, in which the composites damage easily. The compressive properties of the 3D composites increase with the increase of the pile density, material elastic molulus, and decrease with that of the pile height. The results provide reference for the structure optimum of the 3D composites.
