The invention relates to a manufacturing method of structures formed co-bonding second structural components (11) to a first structural component (13). The method comprises the following steps: a) Preparing for each second structural component (11) an ensemble (19) wherein a preform (20) of it, surrounded by a band (23) of a suitable material to form a vacuum bag, is disposed between curing tools (21, 21') which are thus in contact with the bag and not with the preform; b) Positioning said ensembles (19) on the first structural component (13) and forming the vacuum bag (31) for the complete structure joining said bands (23) and complementary pieces; c) Applying to the resulting assembly an autoclave cycle.
