Basaltex NV Multidirectional Fabrics 450 are laid in different orientations, layer-by-layer, and stitched together with a lightweight polyester yarn to form a fabric. Respect to woven fabrics, Non-Crimp (NC) fabrics offer better mechanical properties, primarily from the fact that the fibers are always straight and that more orientations of fiber are available from the increased number of layers of fabric. Due to the stitched nature of the multiaxial construction, the crimp effect associated with woven fabric is not present.
