The aim of the research study is to simulate the thermomechanical and kinetic processes of short fiber orientation during polymer crystallization in the filling phase under anisothermal flow in particular circumstances. This simulation shows the material’s condition during and after this phase. We used numerical simulation to investigate the orientation of short fibers in a thermoplastic matrix during injection molding of a composite polymer. The equations of continuous media mechanics, as well as Schneider’s equations, were used in this modeling. The usage of pseudo-plastic viscosity-dependent models requires the coupling of heat transfer and mechanics equations. The numerical solution of these equations was achieved using implicit Runge-Kutta techniques of order 2 combined with the finite difference approach.
