In this article, we presented a complete mathematical model based on Jeffery, Folgar-Tucker model and kinematics of fiber-orientation. Such a model helps to determine the orientation of the short fibers in the molding process, as well as the different physical parameters which influence the studied phenomenon. We are interested in the analysis of the orientation of short fibers in a thermoplastic matrix, through numerical simulation during injection molding of the composite polymer. The orientation of the fibers is usually determined by the coupling flow (fibers-thermoplastic matrix), the flow temperature, and the free movement region of the equation’s kinematic fibers for flow direction. The second-order orientation tensor defines the cinematic of a group of fibers. This analysis is supported by experiential findings.
