摘要Lightweight technology has been applied into automotive and many other industries to enhance the fuel efficiency for many years, especially, fiber-reinforced thermoplastics technology. However, after the high volume used of fiber reinforced plastics, the handling and recycling of this type of materials will become the big problem around the world. One of the recycle methods is based on mechanical method through shredding, crushing, milling, and then reuse. This is a good way to handle without using any chemical or solvent, but it has a poor precision control of microstructure of fibers. It will restrict this kind of recycled fiber content filler to some lower profit of applications. It wonders if it can be redistributed and packed with sand-wich structure using co-injection molding, it might give the recycled plastics a new life with better benefit. Hence, in this study, we will try to investigate the dynamic developing behavior of the core/skin distribution in multi-cavity co-injection molding systems. Specifically, we would like to conduct the interactions among part design, mold design, material properties, and process conditions. Results show that although the inter-actions among various parameters are very complicated, the runner layout and cavity designs have strong in-fluences on the skin/core distribution of co-injection systems. Those influences will be discussed qualita-tively and quantitatively in detailed. Furthermore, the fiber orientations and their effects on the final co-injection parts are also studied. Finally, experimental validation is also performed for both separated and connected cavity systems. It shows both numerical simulation and experimental results are in a good agree-ment.
