It determines the final fiber volume content and thus the necessary press force, the permeability as well as the final mechanical properties. In the present work, the behavior of a uni- and bidirectional carbon fiber non-crimp fabric (UD- & Biax-NCF) with the same fiber type and areal density of fibers in the respective main reinforcement directions is tested in a punch-to-plate setup. Thereby, the influence of the relative fiber orientation at the interfaces of a layup as well as the number of plies is investigated. A combined influence of roving nesting and superposition of stitching patterns is observed. This results in a common influence of decreasing resistance to compaction for higher numbers of layers, while the relative orientation of the interfaces in a layup is only significant for the Biax-NCF.
