Description

State of technology

The The invention relates to a textile-laminated component, which is a carrier material and at least in sections has a textile, which is covered with a protective layer is.

in the Automotive sector is known to consist of struts with a fabric made of carbon fibers to dress and the fabric with a transparent Coat paint. The problem is that the Although carbon fibers have a high strength and rigidity, but one have low elongation at break. This means that the fibers are relative easy to break and brittle are. The fabric made from the carbon fibers is inelastic and therefore adapts to the carrier material bad at. When using carbon fiber fabrics are one Designer set narrow design limits. In particular, it is in Automotive sector so far only known fabrics, leather, painted plastic or wooden beam and aluminum elements for to use the interior decoration. Furthermore, the painting of components consuming, As a rule, several layers of paint must be applied.

task the invention

task the present invention is to provide a component, which gives a designer greater design Freedom gives, and can be easily made.

Subject of the invention

According to the invention this Task solved by that the protective layer is formed as a film by deep drawing applied to the textile. It can be provided that a carrier material, especially one-sided, complete covered by a textile and this textile in turn deep-drawn is clothed with a foil. It is also conceivable that on the support material only in sections a textile or different textiles are applied and the entire carrier material, in particular on the later visible side, together with the textiles in the thermoforming process with the film coated becomes. This means that in sections where a textile is attached, the textile is covered by the film and in sections, which are free of textiles, the film directly on the substrate rests. This results in for a designer most diverse Design options. As a carrier material For example, components of a motor vehicle and mobile phones, in particular covers or housing parts of mobile phones, in question.

at a preferred embodiment of the invention can be provided that the protective layer is formed as a transparent film. Through this measure the textile is visible through the protective layer. By suitable choice of color, pattern or structuring of the Textile can thus influencing and changing the optical properties of the component. This results in for a designer a larger design Diversity.

at an advantageous embodiment can be provided that the protective layer, the textile-laminated component at least partially surrounds positively. This becomes the one causes the textile through the protective layer on the support material is held. On the other hand, a structuring of the textile imaged and preserved on the surface of the protective layer stay.

at a particularly preferred embodiment can be provided that the surface of the protective layer structured is. Thereby can the optical properties of the component are adjusted and changed. The structuring of the protective layer may be due to the structure the underlying textile. Furthermore, it is conceivable that the surface The protective layer is processed specifically to the haptic properties the surface of the component. Also by choosing the structure of Film or the film material, the surface structure, the feel and the appearance of the protective layer are influenced, for example For example, the protective layer may have a smooth, rough, glossy or dull surface.

Particular advantages arise when the textile is designed as an elastically deformable textile, in particular elastically deformable braid, woven fabric, knitted fabric, knitted fabric, or so-called nonwoven, such as a fleece. While a fabric made of carbon fibers is known exclusively as a fabric, an elastically deformable textile can be produced as a woven, knitted or knitted fabric and braid. The advantages of the elastically deformable material are, in particular, the simple processing on the carrier material. The elastically deformable textile can be incorporated more flexibly, for example in curves. In particular, fewer cuts in the textile must be made than is necessary with a carbon fabric according to the prior art. Furthermore, the use of an elastically deformable textile offers a variety of design options. The textiles elasticity and texture can be adapted to the shape of the substrate. As a result, easier handling and processing of the textile can be achieved. By the elasticity of the textile can be avoided that the textile warps when applied to the substrate, as may be the case for example with a carbon fabric. Furthermore, in the case of an elastic material, the textile layer can be applied wrinkle-free.

at different carrier shapes, For example, in the interior of a motor vehicle, can be different textiles are used, which have the same appearance. For example, a textile of a higher elasticity can be applied to a steering wheel be considered on a flat surface, where the same look is achieved with a textile of lesser elasticity can be. This is not possible with a carbon fabric. This will significantly expanded the creative freedom of a designer. The components according to the invention can in particular in the automotive field, preferably in the interior design, application Find. Furthermore, it is conceivable that furniture or everyday objects Such components are finished.

A greater elasticity of the textile and easier disposal (recycling) are achieved when the textile is carbon-free. Preferably, the elasticity of the textile is chosen according to the shape of the component to be laminated, so that in an arrangement of several components of different shapes produced the same visual impression with different textiles can be. In extreme cases, this can occur with one or more components to use an inelastic textile.

The Creative freedom is enhanced when the textile is a luminous fiber or has a fluorescent yarn. The luminous fiber or the fluorescent yarn can, for example be reflective or (electro) luminescent.

The elasticity The textile can already by the nature of their preparation, for example knit or knit fabric. Furthermore, the elasticity of the textile can be influenced when the textile is an elastic fiber or an elastic yarn, especially a rubbery yarn or a rubbery one Fiber.

The Textile is held non-slip on the substrate when by means of a two-component adhesive, in particular dispersion adhesive on the carrier material is glued on. The use of a dispersion adhesive has the Advantage that this solvent-free is. Thus, you can the emission levels in the interior, for example of a vehicle, be reduced.

The Textile leaves arrange itself particularly simply wrinkle-free on the carrier material, if the textile a tailored to the contour of the substrate blank or an adapted stamped part. Also the production of a textile-laminated Component leaves accelerate and possibly even automate.

For the thermoforming process is a carrier material particularly suitable if it is made of plastic or wood is. It is particularly preferred if the carrier material is a plastic part made of PVC, PA, PP, PES, ABS, PS or mixtures of different Plastics is. The plastic part can be replaced by glass fibers, Talc etc. reinforced be.

• • Einbringen des Trägermaterials zusammen mit der daran oder darauf angeordneten Textilie(n) in eine Tiefziehanlage;
• • Überziehen zumindest der Textilie(n) mit einer Folie durch Tiefziehen der Folie.

The scope of the invention also includes a method for producing a textile-laminated component with the method steps:

• At least partially applying one or more in particular elastically deformable textiles onto a carrier material,
• Inserting the carrier material together with the textile or textile (s) arranged thereon or thereon into a thermoforming unit;
• • Cover at least the fabric (s) with a film by thermoforming the film.

This Method can be carried out particularly easily, quickly and inexpensively. Furthermore it is suitable to automate the production of textile-laminated components. On a carrier material, which can be made of wood or plastic, for example a particular elastically deformable textile applied. Around to protect the textile, will follow applied the protective layer. The advantage of using a elastically deformable material is that this is particularly fits well to the shape of the substrate. The textiles can for example on blanks for Door handles, Shift knob, handbrake lever or the like. Are applied. Farther can those coated with the film Textiles on moldings in the instrument area, as inserts in plastic parts, as Seat components or in the center console area of a vehicle use Find. For special applications, for example as a seat component, the textile can simultaneously represent the carrier material. The elastically deformable textile can be different materials natural fibers such as cotton, flax, wool, Silk; Special fibers: metal fibers, glass fibers, fluorine fibers, aramids, Fiber optic lights; Chemical fibers: natural Polymers (e.g., viscose, cuprous, acetate, triacetate ...), synthetic Polymers (e.g., polyester, polyamide, elastane, polyacryl, modacrylic, Polypropylene, polyethylene, polyvinyl chloride, Vinal PVA ...) or Mixtures of different materials.

For deep drawing basically any thermoformable material can be used. Insbesonde In addition, thermoplastics such as PVC, PA, PP, PES, ABS and PS can be used.

there can be provided that for thermoforming the film, in particular a plastic film or a plastic from which the film is pulled will, first by heating is softened and then over the brought with the or the textile (s) provided carrier material and the film and at least the fabric (s) then in contact with each other to be brought. After cooling the Foil is this form-fitting on the textile or in sections where no textile is provided is, on the substrate at. The film can have a surface texture have, for example, was produced by perforation or embossing.

Preferably is during thermoforming by applying a negative pressure the film to the textile (s) is sucked, in particular brought into positive engagement. So can a structure of textile on the surface of the finished textile-laminated Component be imaged.

at In a preferred variant of the method, the carrier material is attached to a workpiece holder arranged and together with the workpiece holder in the thermoforming system brought. The workpiece holder must be designed so that the substrate to be coated, especially plastic part, safely positioned and the finished Component can be demolded well.

To the application of the film, the component is advantageously on Measured, especially milled to measure. Then you can the component with templates, in particular original components, to be checked.

In conclusion, can the supernumerary Foil, in particular with the use of heat, bent and cut become. This can be done by hand or by machine.

Further Features and advantages of the invention will become apparent from the following Description of an embodiment the invention, with reference to the figures of the drawing, the invention essential Details show, and from the claims. The individual characteristics can each individually for one or more in any combination in a variant be realized the invention.
