Abstract:
1. A method for manufacturing a body including a honeycomb structure, comprising: forming with a forming process a plurality of substantially identically shaped sheet-metal parts in the form of circular rings having a first radius and a second radius radially outwardly of the first radius, the sheet-metal parts having a wave structuring having peaks and troughs extending in a circumferential direction of the sheet-metal parts, a pitch between the peaks and troughs being greater at the second radius than the first radius, a thickness of each sheet-metal part being substantially identical from the first radius to the second radius; arranging the plurality of sheet-metal parts adjacent to one another and radially offset to one another; joining the adjacent sheet-metal parts together to form the honeycomb structure; wherein the wave structuring of the circular ring sheet-metal parts is curved, in a plane extending normally to a central axis of the body and between the first radius and the second radius, to be non-parallel to a radial direction.
