| 摘要 |
The present invention relates to a curved rear pressure bulkhead (1) made of a composite material, comprising three layers: an outer layer (2) and an inner layer (3) symmetrical with one another, which are made of a fiber laminate, and the intermediate layer or core (4) made of a lightweight material. With such a sandwich-type shape, the resulting bulkhead (1) is able to withstand the bending loads coming from the strain. and pressurization of the fuselage without having to increase its stiffness by means of using some type of stiffener. The bulkhead (1) comprises a ring (6) that is attached to the ends of the sandwich. shape. This ring (6) is split into several parts (8) to facilitate the assembly of the bulkhead (1) made of composite material to the fuselage skin (5).
