High mechanical properties in combination with low density are key features forlightweight constructions in automotive and aerospace applications. The combination between theinnovative thixoforging process and the potential of fibre or particle strengthened composites withmetallic matrices (MMCs) provides an efficient manufacturing process of structural components withcontinuous or gradient reinforcements.The scope of the Center of Competence for Casting and Thixoforging Stuttgart (CCT) contains newsemi-solid manufacturing methods for metal matrix composites which have been developed andapplied for patent pending. While previous research projects were focussed on fabrication ofcontinuous fibre reinforced metal matrix composites, the local reinforcement insertion, located in thecenter of high force and torsion load zones, is going to be the next evolution step of the CCT researchteam. Therefore it is essential to verify, to simulate and to reproduce the process during infiltration ofthe semi-sold matrix metal into the textile layer experimentally.This paper illustrates investigations regarding the infiltration process of the thixotropic cast-alloysAlSi7Mg0.3 (A365) into laminated fibre woven fabrics by computational fluid dynamics andfluid-structure interaction analysis, taking account into specific manufacturing technology, therheological behaviour of the alloy with special focus on infiltration behavior
