Embodiment Construction

[0043] figure 1 A cross-sectional view is shown of a structure that will have a plurality of components bonded to each other to produce a large-scale structural component 1 according to the method of the invention.

[0044] For example, the large-scale structural component 1 can be a landing flap, a cover skin of an airfoil, a steering unit, a lifting unit, a fuselage skin part with a plurality of windows eg cut away or similar. now refer to figure 1 The steps of the method of the invention are described in more detail below.

[0045] In order to carry out the method, the components 2, 3, 4, 5 and 6 are placed, positioned and mutually aligned with respect to each other on the support structure 7. exist figure 1Part 2 in the exemplary embodiment shown in is a skin panel composed of an aluminum alloy that will be glued to the positioned parts 3 to 6 to reinforce the parts 3 to 6 . The components 3 to 6 can also be referred to as stringers or reinforcing profiles with a subs...

Abstract

The invention relates to a method for autoclave-free adhesive bonding of components (2-6) in order to form in particular, large-sized structural components (1) for aircraft. Since the curing of the least one adhesive film (16) in order to connect the stringers (3-6) takes place free of autoclaves in a vacuum bag at a relatively low partial vacuum between 70 kPa and 100 kPa, the previously necessary complex structure by masking sharp edges and / or arranging pressure elements on order to increase the local contact pressure in specific regions of the components is dispensed with.

Description

technical field [0001] The invention relates to a method for the autoclave-free adhesive bonding of several parts to form, in particular, large-scale structural parts for aircraft. Background technique [0002] The manufacture of large-scale structural components in the aircraft industry today is usually done by bonding metal parts together so that at least the necessary rivet connections can be reduced. For example, complete fuselage skins are now manufactured by bonding stringers and / or window cutout reinforcements (doublers) to aluminum alloy panels. Wing skins of large dimensions can be produced economically in terms of time and costs by this method of bonding stringers and / or transverse ribs. In this way not only monolithic structures but also sandwich structures of the metal plate-honeycomb structure-metal plate type can be produced. [0003] For bonding the individual components, adhesive films with a substrate material (backing plate or fibers) impregnated with a p...
