Definitions
- the present invention relates to an electrical conductor, in particular heating conductor, with a supporting structure and an electrically conductive conductive material, wherein the supporting structure is formed from a fiber composite, and the conductive material consists of a carbon material adhering to the fiber composite. Furthermore, the invention relates to a method for producing an electrical conductor, in particular a heat conductor, with provision of a support structure made of a strand-like fiber composite, arrangement of the support structure according to a desired conductor geometry and fixation of the conductor geometry by means of a deposited on the fiber composite carbon material.
- the present invention is therefore based on the object to propose an electrical conductor or a method for producing an electrical conductor, which enables the production of even spatially complex conductor structures or conductor arrangements in a particularly simple manner.
- the electrical conductor has a support structure and an electrically conductive conductive material, wherein the support structure is formed from a fiber composite, and the conductive material consists of a carbon material adhering to the fiber composite.
- the inventive construction of the electrical conductor thus enables the production of the conductor based on a fiber composite, which serves as a support structure, and with respect to the desired conductor geometry of the conductor is easily deformable or can be arranged. Since the conductive material consists of a carbon material, it is not necessary for the fiber composite serving as the supporting structure to have electrically conductive properties. Rather, the electrical conductivity properties can be taken over only by the conductive material, which adheres to the fiber composite.
- the fiber composite of the support structure or the fiber composite forming fibers are electrically conductive, such as carbon fibers.
- the conductive material not only serves to realize the electrical control function, but also serves to stabilize or fix the fiber composite in the desired, the geometry of the finished conductor defining arrangement.
- the conductive material consists of pyrolytically deposited carbon on the fiber composite, since the sublimate deposited from the gas phase on the fiber composite ensures uniform coating of the fiber composite.
- a deposition on the fiber composite is to be produced which has a comparatively thin layer thickness, then it is advantageous to provide a deposition produced on the fiber composite by using a CVI (chemical vapor infiltration) method. Moreover, corresponding conductors which have deposited on the fiber composite by means of a CVI method have a comparatively increased penetration of the fiber composite with the vapor deposited carbon so that such conductors have increased flexural strength.
- CVI chemical vapor infiltration
- the electrical conductor according to the invention may also comprise a conductive material made of carbonized carbon material, so that, if required, the electrical conductor according to the invention can also be produced in an alternative manufacturing method. It is particularly advantageous in this context if the conductive material is formed from glassy carbon, which can be produced in a manner known per se particularly simply by carbonization of a resin applied to the fiber composite, in particular phenolic resin.
- the conductor according to the invention does not necessarily have to have a fiber composite with conductive properties as a supporting structure, it can prove advantageous, for example for setting a desired total electrical resistance of the conductor, the fiber composite of electrically conductive fibers, in particular carbon fibers, manufacture.
- the carbon coating is provided with a further coating of silicon carbide, for example in a pyrolysis process, e.g. CVD, can be applied.
- a pyrolysis process e.g. CVD
- the additional silicon carbide coating on the one hand creates a particularly dense, hard surface, on the other hand, a special oxidation protection is realized.
- the method according to the invention for producing an electrical conductor comprises the method steps of providing a support structure of a strand-shaped fiber composite, arranging the support structure according to the desired conductor geometry and shape fixing the conductor geometry by means of a carbon material applied to the fiber composite.
- a preferred possibility of applying the carbon material to the support structure is to deposit carbon pyrolytically on the fiber composite.
- a further advantageous possibility for applying the carbon material is to apply a carbonaceous, in particular organic, substance to the fiber composite and subsequently to carbonize it.
- a heating conductor which has a coating of glassy carbon on the outside, in particular if a resin is used as the carbonaceous substance.
- FIG. 1 illustrated flow diagram for producing a heat conductor 10 ( Fig. 3 ) describes the production of the heating conductor 10 based on a strand-shaped fiber composite 11, the in Fig. 2 is shown and arranged to define a spatial arrangement or conductor geometry 13 on a shaped body 12.
- the strand-shaped fiber composite 11 in the present case consists of a braided hose made of carbon fibers, the hose wall of which is formed like a strand.
- Such braided hoses are used as a standard semi-finished in the carbon fiber technology.
- a fiber composite as a starting base for the production of the heat conductor 10, which consists of non-conductive fibers, for example of aluminum oxide.
- the circumference of the shaped body 12 correspondingly formed conductor geometry 13 can be arranged in a simple manner, for example by fixing only of ends 14, 15 of the fiber composite 11 on the molded body 12 defined.
- a deposition of carbon from a gas phase onto the fiber composite 11 during the arrangement of the fiber composite 11 on the shaped body 12 takes place according to a preferred variant of the method ,
- the deposition is from a methane phase in a vacuum under conditions which allow for so-called chemical vapor infiltration (CVI) in which Course of the carbon from the gas phase sublimated not only on the surface of the fiber composite, but rather penetrates the fiber composite and provides for a connection of fibers 19 with each other in the fiber composite 11, such as in Fig. 4 shown.
- CVI chemical vapor infiltration
- a bridge formation 20 between the fibers 19 results in a high degree of stiffening of the fiber composite 11.
- the final product can already be achieved after the above-described shape fixation by means of the CVI method.
- a second carbon deposition can be applied.
- the CVD method can preferably be used, since a penetration of the fiber composite 11 with carbon has already been achieved by means of the CVI method, and so an accelerated layer structure can be achieved in the production of the second carbon sublimate.
- deviating layers such as, for example, TiC, TiN, Al 2 O 3 , ZrO 2 or combinations thereof.
- the application of these layers can be carried out using the respectively suitable methods, such as, for example, PVD, immersion in flowable, fluid or paste-like coating materials, plasma spraying, etc.
