PRESSURE BULKHEAD FOR A PRESSURIZED CABIN OF AN AEROSPACE CRAFT, AND AN AEROSPACE CRAFT

The invention relates to a pressure bulkhead for a pressurized cabin (30) of an aerospace craft (28), wherein the pressure bulkhead (10) comprises: a pressure wall (14) and a frame (12) for connecting the pressure wall (14) to the aerospace craft (28); wherein the frame (12) is connected to the pressure wall (14); wherein the pressure wall (14) has: a core layer (18); and a first covering layer (16) and a second covering layer (17); wherein the core layer (18) is arranged between the first covering layer (16) and the second covering layer (17); and wherein the core layer (18) comprises an auxetic foam. The invention thus provides an improved pressure bulkhead (10) which has increased stiffness, thus ensuring that smaller bending deformations and lower stresses occur and hence that costs can be saved, and that the volume of the pressurized cabin which can be made available to the crew and passengers is maximized.
