The composite sealing structure comprises a carrier ring (33) and a sealing element (35) housed in an annular groove formed between a circumferential outer wall and two side walls of the carrier ring (33). The sealing element has a first region in surface-to-surface contact with the annular groove and a second sealing region (35.12) protruding from the annular groove. A fastening arrangement couples the sealing element (35) and the carrier ring (33) to each other. The fastening arrangement comprises a plurality of fastening pins (37) arranged circumferentially about the axis of the carrier ring. A method for manufacturing the sealing structure is also disclosed. 复合密封结构包括承载环(33)和密封元件(35)，该密封元件(35)容纳在形成于承载环(33)的圆周外壁与两个侧壁之间的环形凹槽中。该密封元件具有第一区域和第二密封区域(35.12)，第一区域与环形凹槽为表面-表面接触，第二密封区域从环形凹槽突出。紧固布置将密封元件(35)和承载环(33)彼此联接。紧固布置包括围绕承载环的轴线周向地布置的多个紧固销(37)。还公开了一种用于制造密封结构的方法。
