Sound-attenuating composite component with honeycomb core and production method therefor

An acoustic insert body for a honeycomb for attenuating sound waves, in particular for attenuating the operating noise of an aircraft,

• the insert body having a main axis and being insertable into a honeycomb cell, in particular into a hexagonal honeycomb cell, in such a way that the main axis runs in the depth direction of said honeycomb cell, and
• the insert body comprising a cohesive surface, and, relative to the direction of the main axis, a first end and a second end,
• wherein the cohesive surface of the insert body has surface regions, spaced from one another in the direction of the main axis, which face one another and overlap, in particular are aligned, in a projection onto a plane lying perpendicular to the main axis in order to demarcate a passage for sound waves between these surface regions in the direction of the main axis and to subdivide the honeycomb cell into a plurality of cavities which are demarcated in the direction of the main axis by the mutually facing surface regions.

A method for producing a composite component for attenuating sound waves, the method comprising:

• providing a honeycomb, and
• inserting acoustic insert bodies into honeycomb cells of the honeycomb,
• comprising producing the insert body using an additive manufacturing process, such that an insert body in each case has a cohesive surface.
