We propose an analytical model for estimating the elastic modulus of a composite flat bar with a flat braiding structure. This analytical procedure includes two. steps : three-and two-dimensional stress analysis. In the first step, the composite fiat bar is assumed to combine with several local parts which have different fiber weave geometries. The elastic moduli of each local part are calculated by three-dimensional analysis. In the three-dimensional analysis, the fibers in the composite fiat bar are expressed by a network of beam elements. Therefore, it is easy to consider the weave geometries and he dimensions of fibers. In the second step, the elastic modulus of the flat bar is calculated from the elastic moduli of local parts using two-dimensional analysis. The numerical results are compared with experimental data. An excellent agreement is found between the analytical predictions and the experimental data. Moreover, it is clear that this analytical model can estimate elastic modul for different weare geometries, such as those including the middle-end-fibers, if the network and the dimension of beam elements in the first step are changed.
