Abstract
A process for manufacturing structured material by providing cellulose fibers and at least one filler and/or pigment, combining the cellulose fibers and the at least one filler and/or pigment, fibrillating the cellulose fibers in the presence of the at least one filler and/or pigment until a gel is formed, subsequently providing additional non-fibrillated fibers, and combining the gel with the additional non-fibrillated fibers.
