The invention belongs to the aerospace manufacturing technology, and relates to a preparation device of an aircraft composite material fuselage wall panels and a preparation method thereof.

In the preparation method of the aircraft composite material fuselage wall panels, the phenomenon of internal corner ester enrichment and external corner attenuation of the cap-shaped stringers can be effectively reduced by adopting an atmosphere feeding manner and a rubber soft mold process, so that the part thickness uniformity is improved; and one-way prepreg is required to be filled in cementing R areas in cementing assembly, and +- 45-degree laying layers are added, so that the stress concentration caused by the R areas, formed between the cap-shaped stringers and the skins, structurally bearing external loads can be relieved. Air bags in the cementing formation process are used as pressure transfer mediums in the cap-shaped stringers and cavities of the skins, and are capable of effectively guaranteeing the formation quality of the skins and cementing surfaces of the R areas.
