Tubular components for aeronautical fuselages and processes and jigs for its manufacturing

A process for manufacturing a tubular-shaped component (19) for aeronautical fuselages made of composite materials comprising an outer skin (1) without joints having a cylindrical or cylindrical-conical shape, a plurality of stiffeners or stringers (2) longitudinally arranged in said outer skin (1) and a plurality of anchoring elements (3) for anchoring other elements to subsequently be incorporated to the tubular component (19), transversally arranged between said stiffeners or stringers (2), comprising the following steps:

• a) Providing a jig (18) with an outer surface having a shape similar to the inner surface of the tubular component (19) including slots (7, 8) for housing the stiffeners or stringers (2) and the anchoring elements (3), respectively;
• b) Providing the stiffeners or stringers (2) and anchoring elements (3) and arranging them in said slots (7, 8);
• c) Laminating the outer skin (1) on the jig (18);
• d) Applying an autoclave curing cycle to the assembly of the jig (18) and the tubular component (19) provided with a curing membrane (20);
• e) Extracting the tubular component (19) by means of a longitudinal movement after the shifting of those elements of the jig (18) which prevent it.
