Abstract

In this paper a workflow is proposed for an enhanced fiber orientation prediction in injection molding of short fiber-reinforced thermoplastics. The workflow is easy-touse, as the final fiber orientation prediction is integrated into the commercial software Moldflow®. For a given material with polymer matrix P and a volume fraction x of fibers, four steps have to be performed: 1) Generating a representative volume element (in the following, referred to as cell) with volume fraction x and mean fiber length, 2) Shearing of the cell using a mechanistic fiber simulation, 3) Calculating the transient fiber orientation tensor and fitting macroscopic parameters and 4) Performing the fiber orientation analysis with the optimized macroscopic parameters in Moldflow®. Based on experimental data, the pARD-RSC model was selected as macroscopic simulation model. It was implemented in Moldflow®via the Solver API feature. The enhanced workflow is validated at the example of two industrial applications with different polymer matrices and different fiber volume fractions. With the proposed workflow, we observe equal or higher accuracy of fiber orientation estimation in comparison to Moldflow®fiber orientation models RSC and MRD.
