In the automotive industry, injection molded components are often used due to their ability to create complex shapes and increase production volume. In order to strengthen these parts, milled or chopped fibers will often be mixed into the matrix to improve the performance of the polymer. However, the complexity of this material is also increased leading to more influence from processing parameters and material variability. Along with inclusion aspect ratio and volume fraction (VF), an important attribute of this material that affects the part stiffness and strength is fiber orientation due to the injection molding process. In this paper, a workflow is presented to predict the mechanical properties of an injection molded part using only injection molding simulation and constituent material properties to build microstructural finite element models (FEM).
