The second time develop of the ANSYS was realized by using APDL language, and an ovoid sectional multi-scale unit cell model for fiber bundle section with pre-made defects was established. At first the initial modulus, the strength and the ultimate strain of fiber bundle were calculated. Then the unit cell model of C/SiC woven composites was established according to the SEM photographs. By introducing the periodic boundary conditions, the initial anisotropic constants of C/SiC woven composites were predicted. The failure criteria proposed by Linde was utilized to set up the progressive damage mode,and the C/SiC plain weave composites with defects under unidirectional tension was simulated. So,the damage evolution process of the fiber bundle could be interpreted, when the unit cell of C/SiC plain weave composites was under the unidirection load. The numerical results show that the proposed model accurately captures the data from the experiments, which demonstrates the validity of the present analytical model. Furthermore, the numerical model provides an alternate way to design and predict the mechanical properties of plain weave composites.
