Detailed Description

Fig. 1-7 show various stages of a method for making a composite component 10 having an integrated electrical conductor circuit 12. The different means 22, 26, 32, 34, 42, 46, 54, 56, 70 shown in fig. 1 to 7 for performing the method are part of an apparatus; the apparatus is generally designated 14 for making a composite material part having an integrated electrical conductor circuit 12. Fig. 9 shows an example of the use of a composite component 10 of this type. The apparatus 14 may be, for example, a production facility for producing a composite material part 10 which has been used in principle, for example, in aircraft manufacture, but with the modifications listed below.

Fig. 1 provides a support 16, the conductor circuit 12 being first applied to the support 16. The support 16 used is in particular a separating membrane 18 or a pull-off membrane. The separation membrane 18 used is, for example, a separation membrane which is currently used in a similar manner for the production of composite parts.

As shown in fig. 2, electrical conductor circuit 12 is then applied to first surface 20 of support 16. The application takes place in particular by means of printing.

Fig. 2 shows an exemplary embodiment of a conductor circuit application device 22, by means of which conductor circuit application device 22 a predetermined pattern of conductor tracks 24 is applied by selective application of an electrically conductive material, in particular a metal.

For this purpose, the conductor-circuit application device 22 has in particular a conductor-circuit printing device 26 for printing the conductor circuit 12. The conductor circuit printing device 26 has a conductor circuit application controller 28, wherein the pattern to be manufactured is stored in a memory as a corresponding file and the conductor circuit application controller 28 is designed to move a moving apparatus 30 (e.g. a robot arm) of the conductor circuit printing device 26 and to actuate a metallic material providing device 32, which metallic material providing device 32 is designed in particular as a printing nozzle for providing the metallic material to the conductor tracks 24.

Fig. 2 also shows a separation film supply device 34, by means of which separation film supply device 34 the separation film 18 can be supplied for printing purposes. By way of example, the separation membrane 18 may be unwound from a suitable supply spool 36.

As shown in fig. 2, the printing head 38 is moved and actuated on the first surface 20 of the separation membrane 18 for correspondingly printing the conductor tracks 24 in a manner controlled by the conductor circuit application controller 28 according to the pattern stored therein for forming the conductor circuits 12.

Thus, under controlled laboratory conditions, electrical conductor circuit 12 can be prepared in a highly accurate manner from high quality electrically conductive materials.

According to fig. 3, a heat-activatable adhesive 40 is then applied to the conductor circuit 12.

To this end, one exemplary embodiment of an adhesive application device 42 is shown in FIG. 3.

The adhesive application device 42 has an adhesive application controller 44 for controlling the application process of the adhesive 40. By way of example, the adhesive application controller 44 is connected to or designed in conjunction with the conductor circuit application controller 28 such that the predefined pattern of conductor traces 24 can also be used for movement control of the adhesive application device 42.

The adhesive application device 42 has an adhesive providing device 46 for providing the adhesive 40 in a free-flowing form.

The adhesive 40 is provided as a heat sensitive adhesive. In particular, an adhesive 40 is provided, the adhesive 40 being activated at a temperature above a predetermined activation temperature and cured at such temperature. In particular, a thermosetting adhesive is provided.

The adhesive application device 42 has an application tool 48 (e.g. with a nozzle 50, a brush (not shown), etc.) which can be controlled with respect to its position by means of a further movement device 52 (e.g. a gantry system) to conform to the contour of the conductor tracks 24 of the conductor circuit 12.

The adhesive application device 42 may be disposed at the same location (e.g., a preparation station of the apparatus 14) or at another station, such as the conductor circuit application device 22. In the latter case, the support 16, which is designed, for example, as a separating membrane 18, is transported from the conductor-circuit application device 22 shown in fig. 2 to the adhesive application device 42 shown in fig. 3 by means of a suitable transport device 54.

Application of adhesive 40 occurs on the side of conductor trace 24 and/or other components of conductor circuit 12 that are offset from separation membrane 18.

In this way, the temperature sensitive adhesive 40 is applied to the conductor circuit 12 by means of the adhesive application device 42. In a similar manner, insulation (which is formed of layers) and protective material may also be added to the site.

A conveyor 54 or another conveyor 54 transports the support 16 from the adhesive application device 42 to a composite part green body providing device 56. The conveying steps are illustrated in fig. 4 and 5, where fig. 4 also shows that by appropriately flipping or otherwise orienting the support 16, the first surface 20 (which is provided with the conductor circuit 12 and is initially upwardly facing) is directed towards a component surface 60 of the composite component blank 58, which component surface 60 is to be provided with the conductor circuit 12.

The composite part blank providing apparatus 56 may be any preparation apparatus that provides a blank to a fiber-reinforced composite material that includes fibers embedded in a matrix material. By way of example, components of an aircraft 62, in particular an aircraft 64, or components of a wind power plant 66 (as shown in fig. 8 and 9) are pre-formed by means of a provision device 56 of this type.

During the otherwise usual preparation of the composite part 10, in particular by means of a suitable function of the conveying device 54, the support 16 (which is designed, for example, as a separating membrane 18) is turned over and brought into direct contact with the last layer of the composite part blank 58. The subsequent composite part 10 (which will be prepared from the composite part blank 58 by curing) may be in particular a panel of a blade 68 of an aircraft 64 or a wind power plant 66, which panel is formed from a fibre-reinforced plastic (such as for example a carbon fibre-reinforced plastic or a glass fibre-reinforced plastic).

In fig. 5, direct contact is preferably made on the component surface 60, the component surface 60 being directed outwardly or inwardly during subsequent operation. Support 16 is preferably applied to part surface 60, with part surface 60 later surrounded by "vacuum packaging (" bag side ").

The separation membrane 18 may also be placed on a tool side facing the molding tool ("tool side") or on an inner surface, such as a flange or the like.

When contact is made, the first surface 20, and in particular the conductor circuit 12 (which is applied to the first surface 20), is in contact with the component surface 60 with the adhesive 40 interposed therebetween.

Fig. 6 illustrates the step of curing the composite part blank 58, thereby preparing the composite part 10. A curing device 70, which in a known manner has a mould 72 (e.g. a moulding tool), an autoclave 74 or furnace and possibly a press or vacuum packaging device (not shown), is used for this purpose.

The curing device 70 is further provided with a temperature control device 78, the temperature control device 78 controlling the temperature of the composite part 10 during curing by means of a heating device. In the process, a temperature higher than the activation temperature of the adhesive 40 is reached.

In addition, the support 16 is pressed together with the composite part green body 58 by appropriate pressure in a press 76 and/or autoclave 74 (which may be similarly controlled) such that the adhesive 40 cures at elevated temperature and pressure while the composite part green body 58 cures.

In one process, the composite part blank 58 is included in a film along with the separation film 18 (which is applied to the composite part blank 58 and subjected to a vacuum) so that a very tight package is prepared and the mold is consolidated. The composite is then moved to an autoclave 74 for curing purposes. In the autoclave 74, the high temperature (e.g., 120 ℃ to 180 ℃) activates the adhesive 40, thereby ensuring a good adhesive connection between the conductor circuit 12 and the composite part 10.

When the curing step has been completed, the composite part 10 is removed from the autoclave 74, as shown in fig. 6.

The support 16, which is designed, for example, as a separating film 18, is removed from the composite component 10, wherein the conductor circuit 12 remains adhesively bonded to the component surface 60 under force.

After the separation membrane 18 is removed, the printed conductor circuit 12 remains strongly connected to the composite part 10 in this way.

Thus, the composite part 10 provided with the conductor circuit 12 may be used for different purposes.

As an application example, fig. 8 shows an aircraft 64 as an example of a vehicle (in particular an aircraft). Here, for example, the panel (which forms, for example, a sub-region of the wing) can be formed from a suitable composite material part 10, so that the electrical devices on the wing can be actuated by means of the conductor circuit 12.

Fig. 9 shows a wind power plant 66 as another example of a possible use of the composite material part 10, the composite material part 10 being provided with a conductor circuit 12. By way of example, the blade 68 of the wind power plant 66 is constructed from a composite component 10 designed as a panel. The conductor circuit 12 integrated therein can be used to actuate a position light 80 on the blade tip. Sensors may also be fitted to the blade 68, which sensors may send wired signals via the conductor circuit 12 and may thus be actuated via said conductor circuit.

It goes without saying that in all application examples, actuators and the like may also be supplied with electrical power and/or control signals via the conductor circuit 12.
