  • Leaf springs or profiles e.g., T-profiles or stringers
  • the textile structure is preferably already adapted or processed in the planar (quasi two-dimensional) textile structure for shaping the three-dimensional semifinished fiber product close to its final contour (for example, contouring or recesses).
