Fiber reinforced polymers are characterized by a superior specific stiffness and strength. But the good material properties can only be found in preferential fiber direction. Therefore, it is indispensable to know the fiber orientation for the design of components and the evaluation of the mechanical component behavior. For long fiber reinforced polymers, such as sheet molding compound (SMC), the fibers are re-oriented due to the material flow during manufacturing. In this respect, the material flow is directly dependent on the component design. Accordingly, there is a direct dependency between design, material and manufacturing, which must already be considered during the initial design phase of SMC components. In order to be able to take the fiber orientations resulting from the manufacturing process into account in the component design, manufacturing simulations are used in the context of virtual product development. For this purpose, the flow behavior during compression molding of SMC has to be calculated. The resulting mechanical behavior of the component can only be predicted by accounting for a sufficiently accurate prediction of the fiber orientations. ... mehr
