1-20. (canceled)
A planar composite material comprising
- a) at least one layer A comprising a fiber nonwoven comprising 40 to 100 wt.-% thermoplastic fibers and 60 to 0 wt.-% reinforcing fibers, or comprising a thermoplastic foil, and
- b) at least two unidirectionally oriented fiber layers B and B′ comprising parallel reinforcing fiber bundles, wherein at least two layers B and B′ have different fiber orientations relative to at least one other B or B′ layer prior to stitching and needling, wherein all layers are both stitched together and also subsequently needled.
