| Abstract: | Using model of rigid rod and bead for Reference,a modified dissipative particle dynamics is established for short fiber composites injection.Then,using modified Verlet algorithm,the filling stage of short fiber composites injection molding is simulated to reveal polymer mesoscopic structure formation and evolution formula by DPD.The results agree with the rule of fiber orientation induced by the flow. |
