ABSTRACT:
The invention relates to a method for producing a fiber composite component having at least one intersection point. An apparatus for producing a component, comprising fiber composite material, including lower and upper dies of a pressing tool and optionally a heat source, by means of which source the fiber composite material can be heated during its subjection to pressure in the pressing tool. To make it possible to produce a non-warping, lightweight, easily manipulated component with at least one intersection point, in particular a grate, it is proposed that an integral component (preform) of the same or substantially the same material thickness and/or the same or substantially the same fiber volume content at the at least one intersection point and adjoining portions of the component is placed in a mold which predetermines or substantially predetermines its final geometry, and before or after being placed in the mold is provided with a monomer such as resin or a polymer and then cured.
