More and more researches have been focused on auxetic composite materials and a number of composite structures have been fabricated, synthesized or theoretically predicted. Since their structures are complex, their mechanical behavior is very difficult to be characterized. The purpose of the present paper is to systematically investigate the negative Poisson's ratio effect of a novel three-dimensional auxetic orthogonal textile composite under compression. Firstly, a set of equations are derived for the theoretical calculation of the Poisson's ratio of the composite under uniaxial compression via an analytical analysis. Secondly, a finite element model (FEM) is created by ANSYS Parameter Design Language and is verified by experiment. The deviation between the simulation and experimental results are carefully discussed. Thirdly, the effects of geometry parameters and material properties on the negative Poisson's ratio behavior of the composite are discussed based on the FEM simulated results. At last, a general basis is concluded. It is expected that the outcomes of this study could be useful to guide the design and fabrication of auxetic textile composites with required negative Poisson's ratio behavior.
