A method for the production of composite material boards from open-pored and closed-pore or, respectively, without pores hardenable materials

摘要

The method involves attaching a non-porous material (1) or closed porous material to a porous layer. The non-porous layer at least is of hardenable material. The open porous layer (2) can be sealed against the air. The as yet unhardened closed porous material is placed over the open porous material and the open porous layer is pre-prepared. The non-porous layer can be applied using low pressure. A sealing support layer (8) can be attached to the opposite side of the porous material to allow suction force to be applied through the porous material to the non-porous covering material.
