A multiaxial non-crimp fabric comprising at least two superimposed layers of multifilament reinforcing yarns arranged within the layers parallel to each other and abutting parallel together. The reinforcing yarns within one layer as well as adjacent layers are connected and secured against each other by sewing threads forming stitches proceeding parallel to and separated from each other at a stitch width w, the sewing threads form stitches with a stitch length s, and the zero-degree direction of the non-crimp fabric is defined by the sewing threads. The reinforcing yarns of the layers are symmetrically arranged in respect to the zero-degree direction of the non-crimp fabric and form an angle alpha to the zero-degree direction, the angle not being equal to 90° or 0°, and the sewing threads have a linear density from 10 to 35 dtex. |
