Influence of flow model calibration on fiber orientation and part performance within an integrative simulation workflow for thick-walled CF-SMC parts

Description

Carbon fiber reinforced sheet molding compounds (CF-SMC) are commonly used for thin-walled interior and exterior parts in different engineering disciplines like automotive and aerospace. Its high specific properties combined with good chemical resistance and easy processing make this type of discontinuous composites very attractive for thick-walled, structural applications too [1]. By compression molding a rapid and cost-efficient way is available for shaping the material into complex 3D geometries such as a motorcycle brake caliper. During this processing step the initially 2D random orientated fibers are redistributed as a result of flow induced forces and interactions like fiber-fiber and fiber-matrix interactions [1, 2]. Therefore, an integrative simulation’s workflow is necessary to utilize the full engineering potential of CF-SMC components. The rheological flow model in compression molding is crucial to predict the correct fiber orientation for the structural simulation [2]. The current study investigates the influence of differently calibrated rheological flow models on the mechanical performance of a novel CF-SMC motorcycle brake caliper design.
