On the basis of previous studies, the structural model of spacer fabric composites were built by using the finite element software ANSYS for analyzing the compressive properties in the paper. The compressive features of the composites were analyzed, and the influence of pile height, pile density and poisson ratio on the compressive properties was studied too. The results revealed that the maximum value of the stress appeared in the interface between the piles and the face-sheets when the spacer fabric composites were subject to compressive loads, in which the composites damaged easily. Another maximum value of the compressive stress occurred in the cross of the “8”-shaped piles, where the piles damaged easily too. And the minimum value appeared in the upper and lower face-sheets, which indicated that the damage didn’t occur easily in the face-sheets. The compressive properties of the spacer fabric composites increased with the increase of the pile density and poisson ratio, and decreased with that of the pile height. The study provides a reference for the structural optimum of the spacer fabric composites.
