Abstract

A non-stitched fiber material (20), a method for manufacturing a component (5) for a wind turbine and an apparatus for manufacturing a non-stitched fiber material are provided. The non-stitched fiber material (20) is configured to produce a pressure drop sufficient to force a layup (9) of fiber material against the mold surface (7) when vacuum is applied to the space between the non-stitched fiber material (20) and the mold surface (7), the non-stitched fiber material (20) comprising a plurality of fibers (22) bonded together by an adhesive (23,30). The method is advantageous in that it avoids openings as found in stitched fiber materials, which allows air through flow. Thus, the non-stitched fiber material has a low air permeability.
