Towards 3D Process Simulation for<i> In Situ</i> Hybridization of Fiber-Metal-Laminates (FML)

Fiber-metal-laminates (FML) provide excellent fatigue behavior, damage tolerant properties, and inherent corrosion resistance.To speed up manufacturing simultaneously increase the geometrical complexity of produced FML parts, Mennecart et al. proposed a new single-step process combining deep-drawing with infiltration (HY-LCM). Although first experimental results are promising, involves several challenges, mainly originating from Fluid-Structure-Interaction (FSI) between infiltration. This work aims to investigate those challenges comprehend underlying mechanisms. A close-to-process test setup is on side, hybrid stack linear simulation model for FMLs presented numerical enabling prediction dry molding forces, local Fiber Volume Content (FVC) within three glass fiber (GF) interlayers, simultaneous fluid progression. The show that deformation required forces predictable. Furthermore, lateral sealing stacks leads deviations intended initially one-dimensional Eventually, demonstrate most flow resistance originates geometrically critical locations. Future will combine these insights focus evaluation during successful part-level application.
