In order to fabricate composite components rapidly, a micro-braiding technique have been proposed and investigated. In the present study, a simple model is proposed to predict the resin impregnation process based on the Darcy's law and the continuity equation. Bending modulus was also modeled considering the difference between tensile and compressive moduli of a carbon fiber and resin impregnation. To confirm validity of the models, carbon fiber reinforced polypropylene composites were molded under various molding conditions. Cross-sectional observation results indicated the model proposed was possible to predict resin impregnation. Four-points bending tests were also conducted on the composites. It is confirmed that bending moduli were well-predicted based on the proposed model.
