Abstract

A pressure bulkhead (1) for an aircraft fuselage (3) having a sandwich structure (5) which defines a central axis (9) and which extends between a circumferential edge area (7), wherein the sandwich structure (5) includes an inner cover layer (13), an outer cover layer (17), and a core layer (19), which extends between the inner and outer cover layers (13, 17) and connects them. The object of providing a pressure bulkhead (1) for an aircraft fuselage (3) which, even in the case of larger fuselage diameters, can particularly effectively absorb the occurring pressure forces and which can also be built with minimal weight, is achieved in that, between the inner and the outer cover layers (13, 17), in addition to the core layer (19), a support structure (23) is provided, which is connected to the cover layers (13, 17) and which extends from the inner cover layer (13) to the outer cover layer (17), and in that the support structure (23) comprises at least one layer (25) which, viewed in a cross section (21) parallel to the central axis (9), extends from a first section (7a) of the edge area (7) to an opposite second section (7b) of the edge area (7).
