METHOD FOR SIMULATING FIBRE ORIENTATION IN AN INJECTION-MOULDED COMPONENT MADE OF A FIBRE-REINFORCED PLASTICS MATERIAL, AND DESIGN METHOD FOR DESIGNING AN INJECTION-MOULDED COMPONENT MADE OF A FIBRE-REINFORCED PLASTICS MATERIAL
The invention relates to a method (100) for simulating fibre orientation in an injection-moulded component made of a fibre-reinforced plastics material, wherein, by means of a macroscopic simulation of the injection moulding process, an orientation of the fibres, which results following injection moulding, in the injection-moulded component to be produced is determined, and wherein the macroscopic simulation of the injection moulding process takes place using macroscopic physical parameters of the fibre-reinforced plastics material. In addition, according to the invention, in the macroscopic simulation, progression of the fibre-orientation tensor Ä over time is determined by combining two macroscopic models, wherein a first progression of the fibre-orientation tensor Äs over time is determined by a first macroscopic model (111) on the basis of shear flows and a second progression of the fibre-orientation tensor Äe over time is determined by a second macroscopic model (112) on the basis of elongation flows. The method is used in a design method for designing an injection-moulded component made of a fibre-reinforced plastics material.
