Patent ID: 8613257

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