Abstract: The present invention relates to a rigid laminate comprising two o more bonded-together carrier layers and possibly one or more intermediate layers, wherein the carrier layers comprise PET, and wherein the amount of PET is at leas 75 wt. %, based on the weight of the total laminate. The present invention furthermore relates to a method of producing a rigid laminate comprising a number of bonded-together carrier layers and possibly one or more intermediate layers, which method comprises the following steps: a) providing a carrier layer that comprises PET; b) applying one or more carrier layers that comprise PET and possibly one or more intermediate layers to the carrier layer obtained in step a); c) subjecting the assembly to such conditions of elevated pressure and heat after step b) that the carrier layers and possibly one or more intermediate layers are bonded to ether.

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.
