DETAILED DESCRIPTION
[0035] Elements having the same function and mode of action are provided in the figures in each case with the same reference signs.
[0036] FIG. 1 shows a bodywork component 10 for a vehicle 100. The bodywork component 10 comprises a base element 11 of carbon fiber-reinforced plastic with base fibers 4 in the form of carbon fibers. The base element 11 may accordingly be understood as a CRP base element 11. The bodywork component 10 further comprises a transmission element 12 of glass fiber-reinforced plastic with transmission fibers 5 in the form of glass fibers, where the transmission fibers 5 or glass fibers, to enable radio signal communication through the transmission element 12, have a higher radio signal transmissibility than the base fibers 4 or carbon fibers. The bodywork component 10 shown in FIG. 1 comprises a bonding means 13 by which the base element 11 and the transmission element 12 are in a substance-to-substance bond with one another. The bonding means 13 is designed in the form of a plastics matrix or corresponding resin. As is also evident in FIG. 1, the transmission element 12 extends over the entire bodywork component thickness or approximately over the entire bodywork component thickness. Only the bonding means 13 extends slightly further, negligibly, and shown to an exaggerated extent in the figures for greater ease of representation.
[0037] FIG. 2 shows a vehicle 100 having a bodywork component 10 according to FIG. 1. More precisely, the vehicle roof 20 of the vehicle 100 comprises the bodywork component 10 shown in FIG. 1. In the case of this bodywork component 10, the base element 11 and the transmission element 12 each extend over the entire bodywork component length. The transmission element volume in this case is around 30% of the base element volume. Moreover, the transmission element volume is around 20% of the total volume of the bodywork component.
[0038] Represented in FIG. 3 is a semifinished product 1 for producing a bodywork component 10 as described above. The semifinished product 1 comprises a semifinished base element 2 with base fibers 4 in the form of carbon fibers, and a semifinished transmission element 3 with transmission fibers 5 in the form of glass fibers. The base fibers 4 and the transmission fibers 5 are each provided in woven form. Moreover, base fibers 4 are partially woven with transmission fibers 5. In other words, the base fibers 4 and the transmission fibers 5 are bonded form-fittingly and force-fittingly to one another. The glass fibers have a higher radio signal transmissibility than the carbon fibers.
[0039] FIG. 4 shows roll product of a semifinished product 1 represented in FIG. 3, from which semifinished product 1 can be cut off according to the cutting line A and the cutting line B. FIG. 5 shows a semifinished product 1 which has been separated according to cutting line A from FIG. 4. In this semifinished product 1, the semifinished base element 2 and the semifinished transmission element 3 each extend over the entire length of the semifinished product. Furthermore, a web of the semifinished transmission element 3 extends between two webs of the semifinished base element 2. FIG. 6 shows a semifinished product 1 which has been separated according to cutting line B from FIG. 4. In this semifinished product 1, the semifinished base element 2 and the semifinished transmission element 3 each extend over the entire width of the semifinished product. Here as well, a web of the semifinished transmission product 3 extends between two webs of the semifinished base element 2. The webs of semifinished product each extend over the entire or approximately over the entire semifinished product thickness of the semifinished product 1.
[0040] FIG. 7 shows roll product of a semifinished product 1 according to a further embodiment, from which semifinished product 1 can be cut off according to cutting line C. FIG. 8 shows a semifinished product 1 which has been separated according to cutting line C from FIG. 7. In this semifinished product 1, the semifinished base element 2 and the semifinished transmission element 3 each extend over the entire width of the semifinished product. Furthermore, a web of the semifinished base element 2 extends between two webs of the semifinished transmission element 3. The webs of semifinished product each extend over the entire or approximately over the entire semifinished product thickness of the semifinished product 1.
[0041] With reference to FIGS. 9 to 12, a method for producing a bodywork component 10 in an illustrative wet compression molding operation is subsequently described. For this operation, first a semifinished product 1 as described above is provided. A choice has been made not to show a detailed representation of how the base fibers 4 and the transmission fibers 5 are interwoven or braided with one another in an initial production process. This may be carried out, for example, in a direct fiber laying process in which tapes of spread roving are laid. As shown in FIG. 9, the semifinished textile product is first cut to the desired length. Subsequently, a plurality of semifinished product layers, as shown in FIG. 10, are placed one atop another and impregnated with a plastics matrix. After a resting phase, the impregnated component, as shown in FIG. 11, is placed into a compression mold 30, where it is brought into the desired shape and also cured over a predefined time and with a predefined pressure. As soon as the component has the desired shape and has sufficiently cured, the compression mold 30, as shown in FIG. 12, is opened and the completed bodywork component can be removed.
[0042] FIG. 13 shows a vehicle 100 having a bodywork component 10 for the vehicle roof, where the base element 11 extends in the form of a frame around the transmission element 12, or the transmission element 12 is designed in window form or in the form of a signal transmission window in the base element 11.
[0043] The disclosure admits further design principles in addition to the embodiments represented. In other words, the disclosure is not to be considered to be limited to the exemplary embodiments elucidated with reference to the figures.
