Definitions

  • the invention relates to a carbon fiber component with a surface area, wherein in the carbon fiber component an opening is formed, which extends transversely to the solicitnaus ⁇ expansion and which is surrounded by a circumferential wall of the carbon fiber component.
  • Carbon fiber devices combine high strength with low weight ⁇ ge. Today, they are often used in the manufacture of technical articles, where a low weight is desired. These include, for example, vehicles and aircraft. In a number of fürspar ⁇ len, it is desirable to be able to initiate an electric current in the carbon fiber component. A satisfactory solution has not been found so far.
  • the invention is based on the object to present a carbon fiber component, with the introduction of electrical currents in the carbon fiber component is possible in a cost effective and zuver ⁇ permissible manner.

  • a contact element which consists of a conductive material and having a current to the customized to ⁇ wall outer surface, and that the Contact element is exposed to a contact force with which the contact element is pressed against the peripheral wall, wherein a component of the contact force acts parallel to the surface area ⁇ chenausdehnung of the carbon fiber component.
  • carbon fiber components are composite components referred to in de ⁇ nen carbon fiber is contained at least in part.
  • the carbon fibers may be embedded in so-called CFRP components in a carrier material, such as an epoxy resin ⁇ .
  • the term also includes, for example, glass fiber reinforced components that are supplemented with carbon fibers.
  • the carrier material is regularly an electrical isolator .
  • the carrier material may also be provided with electrically conductive additives.
  • the term axial direction refers to the axis of the opening. It is not necessary for the contact force to act as a whole in parallel with the areal extent of the carbon fiber component, but it is sufficient if this applies to a component of the contact pressure force. The contact force can therefore also have a component in the axial direction of the opening.
  • the invention is based on the idea of producing the electrical contact, via which electrical currents can be introduced into the carbon fibers, over the end faces of the carbon fibers.
  • the end surfaces are those surfaces that arise when severing a carbon fiber.
  • ⁇ contact resistance at the end surfaces is much lower, so that an effective introduction of electric current is possible here.
  • the electrical conductor, which establishes the electrical connection to the Endflä ⁇ chen in good mechanical contact with the End face stands. Since the carbon fibers are aligned parallel to the FLAE ⁇ chenausdehnung of the carbon fiber component, the end surfaces of the carbon fibers terminate in the peripheral wall of the opening.
  • the invention has recognized that a good electrical contact between the contact element and the end surfaces only arises when a good mechanical contact is given.

  • Carbon fibers have a very low thermal expansion coefficient.
  • the thermal expansion coefficient of the spinachma ⁇ terials, in which the carbon fibers are embedded, is usually much higher. Due to the high mechanical Stability of carbon fibers, however, the carrier material can not extend in the longitudinal direction of the carbon fibers, but the expansion takes place transversely to the carbon fibers.

  • the contact element and the tensioning device can then be mounted without requiring access to the rear side of the carbon fiber component.
  • the diameter of the counterpart in the assembled state is smaller than the diameter of the through hole.
  • the counterpart can then be passed through the through hole.
