Abstract
A sheet which includes a hot-pressed molded thermoset resin sheet, and has a core sheet formed from a prefabricated flat sheet made from wood fibers, cellulose fibers, or wood fibers and cellulose fibers, which have been impregnated with hot-curing phenol-formaldehyde resin. The core has been hot-press-molded, using pressure, with prefabricated curved parts made from wood fibers, cellulose fibers, or wood fibers and cellulose fibers, which have been arranged on a core surface. The curved parts have uniform, nonuniform, or uniform and nonuniform distribution across the core surface. The outlines and the heights of the curved parts are identical or different in size, and the same applies to the shapes of the parts. Located on a frontal and/or reverse side of the sheet there is a decorative layer.
