Embodiment Construction

[0033] exist Figure 1a A first and a second aircraft component 1 , 3 are shown in . The aircraft components 1 , 3 are arranged one above the other, so that the first aircraft component 1 rests on the second aircraft component 3 in a segmental, planar manner. The first aircraft component 1 has a free surface 5 opposite to the surface 7 with which the first aircraft component 1 rests in sections on the second aircraft component 3 . Correspondingly, the second aircraft component 3 also has a free surface 9 , opposite to the surface 11 , with which the second aircraft component 3 rests on the first aircraft component 1 . The first and the second aircraft component 1 , 3 therefore bear against each other with their respective faces 7 , 11 opposite the free faces 5 , 9 .

[0034] The first and the second aircraft component 1 , 3 are formed from a thermoplastic fiber composite material. For example, the thermoplastic fiber composite material can be a PEEK material reinforced with ...

Abstract

A method for connecting two aircraft components made of thermoplastic composite material by means of rivets is described and claimed. The two aircraft components are arranged in sections, planarly, before the openings in the two aircraft components are widened by means of punch elements such that the openings form after widening a continuous opening for receiving the rivets close to each other. In this case, the two aircraft components are locally heated by the punch element, so that the structural element is thermoplastically deformed when the opening is widened. The punch element is introduced through the first opening into the second opening. Finally, the rivets are introduced into the successive openings. Furthermore, a system for performing the method is described and claimed.

Description

technical field [0001] The invention relates to a method for connecting two aircraft components made of thermoplastic composite material by means of rivets and to a system for carrying out the corresponding method. Background technique [0002] When developing future aircraft models, new materials such as thermoplastic composites are considered. Thermoplastic composites stand out especially for their high load-carrying capacity and low weight. Furthermore, aircraft components made of thermoplastic composite materials, in particular thermoplastic fiber composite materials, can also be connected by means of welded connections, which reduces the manufacturing effort compared to conventional riveted connections. However, it is neither feasible nor desirable to completely dispense with the proven rivet connection. Here, a riveted connection can be used alone or also together with a welded connection. The latter has the advantage, in particular, that the rivet prevents the prop...
