Definitions
- the invention relates to a method for producing a trim component and a trim component, in particular a trim part for the interior of motor vehicles.
- trim components are known from the prior art, which provide different optical properties and designs.
- various fiber composite components are also known.
- a structural component for absorbing high forces is known from EP 2 816 916 B1.
- Cladding components should not serve as structural components, but should, in particular, be perceived as aesthetic and appear valuable Provide surface.
- fiber composite components are also used as trim components in the vehicle interior or for the design of certain other vehicle areas, such as in the engine compartment.
- the invention is therefore based on the object of providing a method and a cladding component which are inexpensive and at the same time provide an aesthetically pleasing surface, as in the case of a fiber composite component used as a structural component.
- a method for producing a trim component which comprises the following steps: Arranging fibers on an adhesive film so that one side of the adhesive film is covered flat with fibers, the fibers adhering to the side of the adhesive film;
- the fibers attached to it By removing the adhesive film from the carrier layer, only the fibers attached to it remain on the carrier layer, which are at least partially superimposed due to their disordered alignment. If the protective layer is arranged on the carrier element or on the fibers attached to it, the fibers are thereby in different planes of the protective layer. When viewed from the visible side, differently oriented fibers are visible at different distances from the surface of the protective layer that defines the visible side, which results in an aesthetically pleasing and high-quality surface.
- the fact that no high pressures or temperatures are used in the process means that less energy is required to manufacture the cladding components and the demands on the tools with regard to the load capacity are lower. In addition, the time required to manufacture individual components is reduced, so that the costs for the manufacturing process and the material costs for the trim component are lower are in alternatives known in the art.
- the cladding components are more cost-effective to manufacture and offer a similar or almost identical and valuable appearance.
- the fibers are preferably arranged as a plurality of fiber bundles on the adhesive film, the fiber bundles of the plurality of fiber bundles having mutually different lengths.
- Fiber bundles are also known as roving.
- the fiber bundles are sections or “snippets” of fiber bundles. These are preferably arranged on the adhesive film in a non-aligned manner with respect to one another.
- the fiber bundles or rovings each preferably have a flat or elliptical cross section. The lengths of the roving or fiber bundles influence in particular the visual appearance of the cladding part.
- An advantageous variant of the method provides that when removing the adhesive film, the fibers connected to the carrier layer remain connected to the carrier layer and arranged on it and fibers not connected to the carrier layer, adhering to the adhesive sheet, are removed with the adhesive sheet. As a result, only the fibers directly connected to the carrier layer preferably remain on the carrier.
- the fibers or the fiber bundles are preferably undirected and distributed chaotically to one another in each step of the method.
- the fibers on the adhesive film are arranged in a non-oriented or disordered manner with respect to one another and the fibers connected to the carrier layer are arranged in a non-oriented or disordered manner with respect to one another. If the fibers are applied to the adhesive film as fiber bundles, the fibers of a fiber bundle are essentially parallel to one another, the fibers of different fiber bundles or the different fiber bundles being arranged in a chaotic and non-directional manner with respect to one another.
- the method provides that the adhesive sheet is a statically chargeable sheet, the adhesive sheet is charged with a predetermined static charge, and when the fibers are placed on the adhesive sheet, they adhere to the adhesive sheet by a static attraction caused by the static charge.
- a continuation of the method is advantageous in which the fibers adhering to the adhesive film adhere to the adhesive film in multiple layers at least in sections and form a fiber layer which is determined at least in sections by several fiber layers.
- a layer thickness of the fiber layer is determined by a number of the fiber layers adhering to the adhesive film, the number of fibers adhering to the adhesive film or the layer thickness formed thereby being determined by the predetermined static charge. The higher the static charge, the more fibers are attracted, the more fiber layers are formed or held on the adhesive film and the greater the resulting layer thickness.
- the layer thickness can differ in sections. For example, fewer fibers can be provided in sections or the static charge and the resulting static attraction can be different in sections.
- the adhesive film is made of PTFE
- the adhesive film can also be formed from another statically chargeable material or coated therewith.
- the adhesive film can also be designed as an adhesive element in which one side of the element can be statically charged. There is also one with glue coated adhesive film can be used.
- an adhesive film can also be provided by magnetism or electromagnetism.
- the adhesive film is pressed against the carrier layer when the fibers directly adjacent to the carrier layer are connected.
- a pressing force during such a pressing is comparatively low and is preferably between 0.1 N / mm 2 and 2.0 N / mm 2 .
- the fibers are arranged as a plurality of fiber bundles or rovings on the adhesive film and pressed with the adhesive film against the carrier layer, the fiber bundles or rovings lose their respective original shape and are pressed flat, so that the individual fibers of a roving continue to be essentially parallel to one another run away, but lose their cohesion.
- an adhesive is applied flatly to the carrier layer, so that an adhesive layer is formed on which the fibers of the second plurality of fibers are arranged when the adhesive film is arranged on the carrier layer.
- the fibers lying directly on the carrier layer are connected to the carrier layer by gluing.
- all fibers which are in direct contact with the adhesive layer are considered to be in direct contact with the carrier element.
- the method provides, in an advantageous variant, that the fibers lying directly on the carrier layer are laminated onto the carrier layer by pressing and preferably by heating, so that the fibers are firmly bonded to the carrier layer .
- the protective layer is preferably rigid and scratch-resistant.
- the method provides, according to a further advantageous embodiment, that the carrier layer with the fibers connected to it is reshaped to form a molded layer composite before the protective layer is formed.
- the carrier layer can be designed as a film and in particular as a flexible film, so that the carrier layer with the fibers can be reshaped by being applied to a carrier, the carrier serving to fasten the trim part to the vehicle, for example.
- the carrier layer can be made essentially rigid and can be reshaped by feeding streak or by pressing.
- the carrier layer can also be formed from a fabric together with a thermoplastic layer, the thermoplastic layer being arranged in particular as a thermoplastic film between the fabric and the fibers.
- the composite of the molded layers can be glued onto a carrier or back-injected with a carrier in an injection molding process.
- the protective layer is preferably only applied subsequently.
- the carrier is formed in particular from plastic.
- a cover material is applied to the fibers connected to the carrier layer so that the fibers are covered locally by the material and the protective layer formed therefrom and the protective layer is on a side facing away from the carrier layer the fibers form a closed-pore surface.
- the closed-pore upper surface determines a visible side of the cladding component.
- the material can be applied locally by hand, for example, but also by machine using cannulas.
- the cover material forming the protective layer is transparent and preferably comprises a PMMA (polymethyl methacrylate), PC (polycarbonate) or PUR (polyurethane) material. Alternatively, the material can also be another scratch-resistant and transparent curing lacquer.
- the protective layer can optionally also be formed by a TPU film (thermoplastic polyurethane) or a PUR potting compound or a PUR potting compound (polyurethane).
- the fibers are preferably completely encapsulated and / or saturated by the protective layer.
- the protective layer in particular a protective layer formed from PUR or a protective layer applied as a film, is thermoplastic and thus 3D deformable.
- a TPU film, from which the protective layer is formed preferably has a thickness of 200 to 300 ⁇ m.
- the film is placed on a side of the fibers facing away from the carrier layer and then pressed with pressure and heat with the fibers or against the carrier layer, whereby the protective layer formed from the film has a side facing away from the carrier layer
- a transparent surface layer can also be formed on a surface of the protective layer facing away from the carrier layer, so that the protective layer has an intermediate layer or intermediate layer surrounding the fibers between the carrier layer and the surface layer forms.
- a preferably closed-pore surface of the protective layer determines the visible side of the trim part through the transparent surface layer together with the surface layer.
- the surface layer can be made of PUR (polyurethane) or a scratch-resistant protective varnish. forms are.
- the fibers lie closer to the carrier layer and individual fiber ends do not protrude far from the carrier layer, it can also be provided as a variant that the fibers already connected to the carrier layer are pressed against the carrier layer in an intermediate step after the adhesive film has been removed.
- the fibers are in particular basalt fibers, carbon fibers, plastic fibers, metallic fibers, metallized with metal or other fibers that can be attracted by electrostatic charging. Furthermore, it is proposed in a variant of the method that the fibers are designed as fiber pieces each having a length between 2 mm and 200 mm, preferably lengths of 3 mm to 25 mm and more preferably lengths of 5 mm to 10 mm. If the fibers are arranged as a multiplicity of fiber bundles or fiber bundle pieces on the adhesive film and by means of the adhesive film on the carrier layer, the fiber bundles each have lengths between 2 mm and 200 mm, preferably lengths from 3 mm to 25 mm and more preferably lengths from 5 mm to 10 mm.
- the individual fibers and / or fiber bundles preferably have different lengths in relation to one another.
- the fibers are in particular recycled fibers, which can be obtained, for example, as fiber cut from other manufacturing processes and can be reused in the process proposed according to the invention.
- the fibers are preferably not connected to one another before they are applied to the carrier layer and thus in particular no “prepreg”, fabric, scrim or the like.
- the fibers are not a fleece and are essentially independent of one another.
- the fibers on the carrier layer are therefore chaotic, disordered and non-directional to one another.
- Fibers are preferably provided as fiber strands or fiber bundles which comprise a plurality of individual fibers or fiber filaments aligned in parallel.
- the cladding component comprises a protective layer which forms a visible side of the cladding component, a carrier layer which faces a rear side of the cladding component facing away from the visible side, and a fiber layer arranged between the protective layer and the carrier layer.
- the fiber layer comprises a multiplicity of fibers which are arranged in multiple layers at least in sections from the carrier layer to the protective layer and are aligned irregularly to one another. The fibers are each at least partially connected directly to the carrier layer and overlap one another from sections.
