Definitions
- the present invention relates to a fuel tank and a method of manufacturing a fuel tank.
- CFRP components carbon fiber reinforced plastic components
- Such materials are advantageous in terms of lightweight construction and in terms of rigidity and strength.
- the fuel tank in racing applications is made of carbon fiber reinforced plastic.
- a fuel tank for a vehicle which has a low weight and a long life.
- This object is achieved by a fuel tank for a vehicle, in particular for a motorcycle, with a limited by a wall container for receiving fuel, wherein the wall of the container has at least an inner, first layer and a second layer, and wherein the first Layer is made of a fuel-resistant material and the second layer is made of a carbon fiber reinforced plastic.
- the inner first layer is in direct contact with the fuel received in the container.
- the second layer is outside the first layer and thus is not in contact with the fuel.
- Such a fuel tank according to the invention has the advantage that the weight of the fuel tank over conventional T anks made of aluminum or plastic without carbon fibers is significantly reduced without the life of the fuel tank is impaired. A user does not need to empty the fuel tank because the carbon fiber reinforced plastic does not come in contact with the fuel.
- carbon fiber reinforced plastics have high strength and rigidity.
- a fuel tank with a layer of a carbon-fiber-reinforced plastic can be particularly stable, in particular have high impact resistance and mechanical resistance.
- the container may have a smaller wall thickness than a container of a conventional fuel tank, which in turn is advantageous for the installation space situation in the vehicle.
- the first layer is a coating applied internally on the second layer.
- the first layer has a lower permeability to fuel than the second layer. In this way, the amount of fuel that diffuses through the wall of the container can be reduced to a minimum, so that the permeability can be greatly reduced.
- the first layer contains polyamide or consists of polyamide.
- Polyamide has a particularly low permeability, but is brittle at low temperatures.
- the combination of a first layer of polyamide or of polyamide and a second layer of carbon fiber reinforced plastic creates a load-bearing fuel tank with good permeation values.
- the first layer contains polyketone or is polyketone.
- Polyketone also has a low permeability.
- the first layer may contain polyamide and polyketone or consist of polyamide and polyketone.
- the first layer is, for example, injection-molded onto the second layer and / or applied by a rotational process. In this way, the container of the fuel tank can be manufactured easily and inexpensively.
- the container is preferably provided on its inner side and / or the second layer on its inside over its entire surface with the inner layer. This ensures that the second layer is completely shielded from the fuel and can not come into contact with it.
- the container may be provided on its outside and / or the second layer on its outside with a coating, in particular with a coating.
- a coating in particular with a coating.
- the fuel tank can be visually adapted to the overall design of the vehicle and protected from environmental influences.
- the object is further achieved by a method of manufacturing a fuel tank, comprising the steps of: providing a container of a carbon fiber reinforced plastic, and providing an inner wall of the container of carbon fiber reinforced plastic with a coating of a fuel resistant material.
- the coating is done in particular in a rotation process.
- FIG. 1 shows schematically a cross section through a fuel tank according to the invention.
- FIG. 1 shows a fuel tank 10 for a vehicle, in particular for a motorcycle.
- the fuel tank 10 can be used equally in an automobile.
- the fuel tank 10 has a container 14, which is bounded by a wall 12, for receiving fuel, which has an inner, first layer 16 and a second layer 18.
- the second layer 18 is made of a carbon fiber reinforced plastic. It is thus dimensionally stable and defines the shape of the fuel tanks 10. The second layer 18 can therefore be regarded as a semi-finished product of the container 14.
- the first layer 16 is made of a fuel-resistant material and has a lower permeability to fuel than the second layer 18.
- the first layer 16 is entirely made of polyamide or contains polyamide.
- the first layer 16 is entirely polyketone or contains polyketone.
- the first layer 16 is provided on an inner wall of the second layer 18.
- the first layer 16 is a coating applied internally to the second layer 18.
- the container 14 is provided on its inner side and / or the second layer 18 on its inner side over its entire surface with the inner first layer 16.
- the first layer 16 may be molded onto the second layer 18 and / or applied by a rotational process.
- a fuel tank 10 with particularly advantageous component properties can be provided.
- a fuel tank 10 has a low weight, a small wall thickness, a high Impact resistance and high mechanical resistance, in particular compared to conventional fuel tanks made of aluminum or plastics without carbon fibers.
- the container 14 may be provided on its outer side and / or the second layer 18 on its outer side with a coating 19, which is indicated for the sake of simplicity in FIG 1 only selectively.
- the coating 19 is a paint job.
- the coating 19 extends, for example, over the part or the entire outer surface of the second layer 18.
- Such a coating 19 can serve optical purposes, for example to color-adapt the container 14 to a vehicle body. This often happens with motorcycles, where parts of the fuel tank are visible from the outside.
- the outer coating 19 protects the second layer 18 from environmental influences.
- a container 20 made of a carbon fiber reinforced plastic is provided according to the invention, which serves as a semi-finished product of the container 14. This container 20 corresponds to the second layer 18th
- an inner wall of the container 20 is provided with a coating of a fuel-resistant material 22, for example, in a rotation method or a spraying method.
- the fuel-resistant material 22 forms the first layer 16 after completion of the method.
- the second layer 18 or the container 20 can be provided with a coating 19, for example with a coating.
