Characterization and Simulation of Material Distribution and Fiber Orientation in Sandwich Injection Molded Parts
Kurzfassung in deutsch
In this work, the material distribution, structure of fiber orientation and fiber attrition in sandwich and push-pull injection molded short fiber composites are investigated, regarding the effect of fiber content and processing parameters, given its direct relevance to mechanical properties. The prediction of the tensile strength of conventional, sandwich and push-pull injection molded short fiber composites are derived by an analytical method of modified rule of mixtures as a function of the area fraction between skin and core layers. The effects of fiber length and fiber orientation on the tensile strength are studied in detail. Modeling of the specialized injection molding processes have been developed and performed with the simulation program in order to predict the material distribution and the fiber orientation state. The secondorder orientation tensor (a11) approach is used to describe and calculate the local fiber orientation state. The accuracy of the model prediction is verified by comparing with corresponding experimental measurements to gain a further basic understanding of the melt flow induced fiber orientation during sandwich and push-pull injection molding processes.
