MANUFACTURING METHOD OF COMPOSITE STRUCTURES WITH CURING TOOLS ARRANGED OUTSIDE THE VACUUM BAG

摘要

A manufacturing method of structures formed co-bonding second structural components to a first structural component. The method comprises the following steps: a) preparing for each second structural component an ensemble wherein a preform of the second structural component, surrounded by a band of a suitable material to form a vacuum bag, is disposed between curing tools which are thus in contact with the bag and not with the preform; b) positioning the ensembles on the first structural component and forming the vacuum bag for the complete structure joining the bands and complementary pieces; c) applying to the resulting assembly an autoclave cycle.

1. A method for manufacturing a structure of composite material formed by a first structural component and a plurality of second structural components joining the second structural components in an uncured state to the first structural component in a cured state by co-bonding, comprising the following steps:
a) preparing, for each second structural component, an ensemble formed by a preform of the second structural component disposed between curing tools having previously placed on the curing tools a band of a suitable material to form a vacuum bag so that the preform is surrounded by the vacuum bag material, except the surface to be joined to the first structural component, on which is placed an adhesive layer for the co-bonding, the bands being dimensioned so that at least the zone of the structure located around the second structural components can be covered with the bands; b) placing the ensembles of the second structural components on the first structural component in the areas foreseen for their attachment and forming a vacuum bag joining the bands of each second structural component and complementary pieces of the same material, so that the vacuum bag covers entirely the first structural component; c) applying an autoclave cycle to the assembly resulting from the previous step for performing the co-bonding of the second structural components to the first structural component.
