NUMERICAL SIMULATION AND EXPERIMETAL INVESTIGATION OF FIBER IN INJECTION MOLDING

摘要

A lot of plastic parts are made of fiber-reinforced engineering materials for its superior mechanical properties. Since the flow induced fiber orientation is complex 3D behavior, the final properties of the injected parts become very complicated. In this research, a ribbed flat plate geometrical model is conducted to examine the effect of fibers with various design consideration on injected parts both numerically and experimentally. Results show that the flow induced fiber orientation both numerically and experimentally in a good agreement. Also, it shows the fiber orientation will affect the final injected parts significantly.
