Abstract
The invention relates to the field of forming fibrous structures by needling processes. A process is provided for achieving a desired Z-fiber distribution in a fibrous structure by controlling transport depth during formation of the fibrous structure in a series of needling passes. Each needling pass generates a portion of Z-fiber bundles that penetrate adjacent fibrous layers, the Z-fiber bundles penetrating only those adjacent fibrous layers that need more Z-fiber bundles to attain a predetermined number of Z-fiber bundles within each fibrous layer.
