FEA of flow field of short fiber and rubber composite material during extrusion process

[摘要] Die structure is one of the most important factors that impacts short fibers orientation during extrusion process. As a result, the effects of two kind of die structure which is dam-die and expansion-die on flow field including pressure field, velocity field and the velocity of short fiber and rubber composite material during extrusion process has been researched by Polyflow. The FEA results about the flow field of the short fiber and rubber composite material indicate that, compared with the two kind of dam-die and expansion-die, the dam die is better for short fibers get orientation in rubber matrix during extrusion process than the expansion-die.
