A three-dimensional molded body, a method for producing a three-dimensional molded body and a method for producing an adhesive bond between a polymer-containing material and a molded body having an inorganic porous framework structure in at least partial areas are described. In all cases the porous structure of the molded body comprising inorganic material is brought in contact with a polymer-containing material which is heated until the heated material enters into a joint connection with the molded body based on adhesive interactions, interfacial interactions, electrostatic interactions or any combination thereof, in which the pore-like voids of the porous structure are filled completely with the polymer-containing material, which stabilizes the molded body so that it has dimensional stability after cooling.
