In this paper, the composite reinforced with three dimensional orthogonal woven fabric/epoxy resin was fabricated with vacuum assisted resin transfer model. The tensile behavior in 0° and 90° directions were experimentally executed. The tensile behavior of 3D orthogonal woven composite was numerical simulated based on the unit cell model and compared with the experimental result, the influence of crack damage and stress on fiber, resin and fiber/resin interface was analyzed. The maximum differences between experimental and simulated results are 3.23 % and 7.94 %. The verified model can be used to simulate the other static and dynamic mechanical properties and analyze the influence of the behavior of component material on the mechanical material properties of 3DOWC.
