摘要：

Based on the Folgar-Tucker fiber orientation model, the visualization of water-assisted injection molding three-dimensional long straight pipe was carried out by using Moldex3D. It is found that the fibers in the water channel layer near water inlet tend to be disordered, whereas at the position near the middle and end of water channel, fibers tend to orienting along flow direction; by appropriately increasing the water injection delay time can result in more fibers at the initial direction of the product orienting along the flow direction. In addition, it has also been found that the glass fibers are orientated remarkably in the core layer and slightly in the region near the mold wall. At the end position of the product, the water injection pressure and melt temperature can significantly affects the orientation of the fibers along the flow direction. © 2019, Editorial Board of Polymer Materials Science & Engineering.
