Abstract: A process for producing a thermoformable and/or -embossable fiber/polymer composite using a fibrous lignocellulosic substrate S and a polymer P, which contains i) homogeneously mixing the substrate S and the polymer P, then ii) converting the substrate S/polymer P mixture to a fiber web, and then iii) compacting the resultant fiber web at a temperature not less than the glass transition temperature of the polymer P [TgP] to give a thermoformable and/or -embossable fiber/polymer composite, wherein a) the substrate S comprises acetylated lignocellulosic fibers, and b) the polymer P is thermoplastic and has a TgP≥20° C. The invention relates to a fiber/polymer molding obtainable by the process and a component in motor vehicle construction, in built structures and in furniture which contains the fiber/polymer molding.
