Method for producing a composite component

A method for producing a composite component which comprises a base layer, a cover layer and a honeycomb structure disposed between the base layer and the cover layer, the method comprising:

• applying the honeycomb structure to the base layer such that a multiplicity of honeycomb chambers which are open on a side pointing away from the base layer are formed;
• filling honeycomb chambers in a reinforcement region with granules during a filling procedure, wherein the granules at a processing temperature at which the filling is carried out do not adhere to the honeycomb structure, the base layer or one another;
• removing granules to be removed from honeycomb chambers such that, after the filling of honeycomb chambers and the removal of granules to be removed, each honeycomb chamber in the reinforcement region is filled with the granules up to a granule filling level and honeycomb chambers outside the reinforcement region are free of granules;
• applying the cover layer to the honeycomb structure such that the honeycomb chambers are closed;
• and
• heating the composite component to a first process temperature at which the granules filled into the honeycomb chambers expand to fill up the honeycomb chambers filled with granules, and subsequently to a second process temperature at which the cover layer, the base layer, the honeycomb structure as well as the expanded granules cure, wherein a density of the expanded granules in the honeycomb chambers filled with granules depends on the granule filling level.
