Description

2340066 Method of Achieving a Glued Connection of Planar or Sheet Parts
The present invention relates to a method of achieving a glued connection of planar or sheet parts, in particular panels or sandwich-like structures, e.g. made of composite fibre materials.
There is a frequent requirement for planar or curved, sheet panels or sandwich-like structures made of composite fibre materials to be firmly and permanently joined to one another by glued joints. Particularly in the transport industry, e.g. in the waggon and vehicle construction industry, an increasing number of components made of composite fibre materials are used which are glued to one another,.these glued joints being exposed both to changing weather conditions and also substantial mechanical stresses as a result of vibrations and shaking movements. Special requirements are set in this case for the regions of the individual parts joined together by gluing.
The invention aims to provide a method with which planar or curved parts, e.g..4nade of composite fibre materials, may be glued to one another in a defined manner, in which case the adhesive joint has a long service life in spite of mechanical and weather-related influences, and is simple to produce.
In a first aspect the present invention provides a method of gluing planar or sheet parts, in particular panels made of composite fibre material, wherein the regions of the parts to be glued to one another are 2 provided with tongues which overlap after gluing; the contact faces of the tongues are wetted with adhesive; the parts are pushed together at an angle a in such a way that no contact occurs between the faces of the tongues wetted with adhesive and the adhesive surfaces of the other part during displacement; and after the end position of the parts to be glued to one another has been reached, one or both thereof is/are swivelled so that the angle a is removed.
The method according to the invention enables larger structural surfaces such as curved or flat panels or also sandwich-like structures to be glued to one another simply, quickly and inexpensively in a defined is manner, whereby the -two parts to be joined together, each being provided with tongues, are pushed into one another at an angle, e.g. in a similar manner to that of two clasped hands, and the two parts (or one of the parts) are only swivelled into the appropriate position after they have been pushed fully into one another, said position being where the two parts come to lie essentially in one plane so that the faces to be wetted with adhesive touch one another.
In a second aspect, the present invention provides a method of gluing planar or sheet parts, in particular panels made of composite fibre material, wherein the regions of the parts to be glued to one another are provided with tongues which overlap after gluing; slots are provided in the end regions of the two parts; the contact faces of the tongues are wetted with adhesive; the parts are pushed together in such a way that each tongue of one part is laid over the opposite tongue of the other part; an adhesive joint is achieved between these two parts by applying an adhesion pressure 3 vertically to the panel plane.
In a third aspect, the present invention provides a method of gluing planar or sheet parts, in particular sandwich-like structures made of composite fibre material, wherein the regions of the parts to be glued to one another are provided with tongues which overlap after gluing; the contact faces of the tongues are wetted with adhesive; the webs of the covering skin, left between two adjacent tongues of the two sandwichlike structures when the tongues have been cut out are folded back in such a way that they cover the corresponding regions of the sandwich core and are glued to this core; in order to glue the two sandwich parts, these covering skin webs are wetted in addition to the tongues or their side walls with an adhesive layer which assures further bonding of the sandwich parts; however the webs remaining after the tongues have been cut out may also be cut off so that the sandwich webs are glued directly to one another.
Embodiments of the invention are explained below in more detail on the basis of the drawings, in which advantageous practical examples are shown for achieving the method according to the invention.
Figure 1 shows top views onto the end regions of two parts to be glued together with the constructed tongues; Figure 2 is a side view of the tongues of the two parts; Figure 3a shows the two parts to be glued together at the beginning of the joining process; 4 Figure 3b shows the same view as in Figure 3a together with the wetting of the contact faces; Figure 4 shows another practical example of two parts to be joined together; Figure 5 is a side view of the tongues of both parts, and Figures 6 and 7 show practical examples of sandwichlike structures to be joined together.
In the figures, in which identical parts have been given identical reference numerals, a first sheet part made of a composite -fibre material is given the reference 1, and this part is to be glued with a defined holding force to a second sheet part 2, which is also made of composite fibre material. According to the invention, the end regions of the two parts 1 and 2 are now each provided with tongues 6, 7, and the sides of these which come into contact with the other part after joining, as well as faces 3, 4, on which the tongues 6, 7 come to rest after joining, are wetted with an adhesive 3, 4.
To ensure that the two parts 1, 2 are essentially arranged in the same plane after gluing, the tongues are advantageously each provided with a double fold, as shown in Figure 2, so that the tongues 6, 7 are displaced in relation to one another when they are glued together after overlapping.
Figures 3a and 3b show the method according to the invention which enables large structural surfaces to also be glued together in a defined manner. In this case, the tongues 6, 7 wetted with the adhesives, and therefore also the two parts 1, 2 to be glued to one another, are pushed into one another at an angle a and only after reaching the end position are swivelled so that the tongues of one part come to lie on the corresponding contact face of the other part.
If a transverse stress is now applied to the free surfaces of the tongues 6, 7 not provided with adhesive, and thus also to the joined parts 1, 2, any desired contact pressure can be applied during the hardening process. An even, unimpaired thickness of the adhesive layer is achieved because of the fact that the tongues 6, 7 are not pushed onto the corresponding contact faces of the other part in the same plane.
The displacement possibility of the tongues 6, 7 shown in Figure 2 is particular.1y necessary when areal parts, in particular panels, of some considerable thickness are to be glued to one another. The arrangement shown in Figure 2 with the double fold is particularly advantageous when there are disadvantages for assembly 2S reasons involved in rotating the two parts relative to one another.
However, if rotation of the two parts poses disadvantages, then the arrangement of the tongues 6 and 7 with a comb-like structure shown in Figure 4 may be achieved. In this case, slots 8, 9 are then provided in the end regions of the two parts.
Figure 5 shows that a displacement 12, 121 also occurs between the individual tongues as a result of a double 6 fold, so that the two parts to be joined together remain disposed in essentially the same plane, while the tongues of a respective end region of one of the parts are alternately bent upwards or downwards so as to form the displacement 12, 121 shown in Figure 5.
Figures 6 and 7 show the gluing of two sandwich-like structures of considerable thickness so that faces are formed which extend vertically to the constructed tongues 6, 7. Such sandwich-like structures usually have a foam or honeycomb core 18, which is covered on all sides or on the upper side and bottom side with covering skins 14. According to the practical example shown in Figure 6, webs 13 of the covering skin left is between two adjacent tongues 6 of the first sandwichlike structure 1 when the tongues have been cut out are folded back in such a way that they cover the corresponding regions of the foam or honeycomb core 18 and are glued to this core.
In order to glue the parts 1 and 2, these covering skin webs are wetted in addition to the tongues 6, 7 or their side walls with an adhesive layer 17 which assures further bonding between the two parts 1 and 2.
Such a glued joint of the two parts 1 and 2 to one another results in a particularly good form-fit of the two parts, in which case soft and tough adhesives may be used because of the large gluing surface. As a result, it is also possible to prevent these from being torn apart as a result of brittle fracture of the adhesion point possibly in the case of an impact The contact faces of the structural part 2, on which the corresponding faces of the part 1 come to lie after joining,are given the references 16 and 171in Figure 7.
7 The method according to the invention is superbly suited to joining plane or areal parts, in particular panels or sandwich-like structures made of composite fibre material, such as those increasingly used in the transport industry.
