A method for production of a gypsum fiberboard panel, has the following method steps: production of a mixture of calcined gypsum and fibers; application of the mixture to a gas-permeable and/or air-permeable and/or liquid-permeable conveyor that continuously moves in an advancing direction, at an advancing speed; pre-compaction of the mixture; wetting of the mixture with setting water; post-compaction of the mixture; pressing the mixture to form a gypsum fiberboard panel strand; cutting the gypsum fiberboard panel strand into individual gypsum fiberboard panels; drying the gypsum fiberboard panels; and if necessary, finishing and/or coating the dried gypsum fiberboard panels; wherein for pre-compaction, the mixture is sprayed with a water mist and has a partial vacuum applied to it. Furthermore, an apparatus produces a gypsum fiberboard panel, in particular by carrying out the method, and a gypsum fiberboard panel is produced using the method and/or using the apparatus.

A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving includes the injection of a suspension containing a powder of solid particles into the volume of the fibrous texture. The injection of the loaded suspension is carried out by at least one hollow needle in communication with a loaded suspension supply device, each needle being movable in at least one direction extending between a first face and a second opposite face of the fibrous texture so as to inject the loaded suspension at one or more determined depths in the fibrous texture.
