Abstract
In order to provide customer-specific colouring of a lightweight high-performance fibre composite material (10) serving as precursor material for thermoformed parts, without any resultant impairment of the haptic properties of the textile (11) therein, colour-pigmented reflective coating material is sprayed onto the entire surface of the textile (11) or onto graphically delimited parts thereof, before the textile (11) thus coloured is laminated to the fibre composite material (10).
Description
Oechsler Public Limited Company, 91522 Ansbach (DE) Method for producing a coloured fibre-reinforced plastic and chamfering of such fibre-reinforced plastic, as well as forming the part produced therefrom The invention relates to a method for producing a coloured fibre-reinforced plastic and a colored fibre-reinforced plastic as a primary material as a reshaped part, as it is formed for example as part of a sports product, as a decorative element in the interior of passenger cars of sophisticated equipment or as a battery cover or other housing shell of a mobile phone or as used in other electronic consumer items.
With such a reshaped part, especially on a deep drawing method, conflicting demands are often placed in practice. In particular, despite its extremely flat formation, it should be an extraordinarily flexible and torsion-resistant material with a pleasing appearance and with excellent feel, however, with low material and production costs.
The exterior is outfitted with a definable coloring, but a distinctive structure of a laminated fiber reinforcing fabric is supposed to remain significant in appearance, especially when one is not dealing with simple layouts but more specific interpreted patterns.
In the present case to simplify the representation, it is always spoken only of fiber reinforcing fabric, which may be interpreted in the context of the present invention is equally as well as one or more layers as a knitted fabric, scrim, fiber strands (rovings), felts and the like matting. On hand are mostly defined oriented fibrous structures, that are, for example, are laminated on both sides with transparent thermosetting or preferably, with thermoplastic material to a preferred fibre-reinforced plastic, possibly also to a so-called organic sheets.
Especially with increased mechanical requirements for fibre-reinforced thermoplastic formed parts, it is close to resorting to the fibre-reinforcement of carbon fibers. They exhibit not only very high strength, as a formed part their trade structure also provides a pleasant feel and sophisticated look. Such formed parts, however, because of the electrically conductive properties of carbon and due to the therefore resulting shielding behavior, cannot be used in devices such as, for example, mobile phones, where an antenna is integrated. This deficiency in poor insulation for electronic applications is not found in the also very solid Kevlar and Aramid fibers, but due to their demand for protection helmets and bulletproof vests such fabrics as consumer goods are scarce at reasonable prices.
Therefore mostly remains only the recourse to thermoplastic laminates with the conventional glass fibre reinforcing fabrics, in particular the ones with layers, which = also show very good mechanical strength. However, the appearance of the resulting drawn glassy colourless formed parts is not at all appealing and therefore is unsuitable, particularly when compared to carbon-formed parts, especially for use in higher-priced consumer goods. The individual glass fibers cannot be coloured, to thereby provide the subsequent tissue and the resulting formed parts created a more valuable appearance, because the fibers, caused by the surface structure of monolithic materials, adopt virtually no colour.
Although instead of the individual fibers, the glass fibre fabric as a whole lets itself coat completely before its lamination, by dipping it in a dye bath with colour. Then, the one drying paint that then must still receive a metallic sheen vapor deposition, holds itself to an uneven fibre surface, but it this unevenness runs largely full of color, so that after drying the paint covering the now leveled fibre structure hardly appears as desired in its form and look - at least not more haptic or visually more appealing than in design review; the internal fibre structure has been lost externally.
Furthermore, as a result, the metallization yet again has the disadvantages of electrical conductivity.

To colour a lightweight high performance fibre composite material that serves as a fibre-reinforced primary material for thermoforming Formed, that is without metalisation custom brilliant colouring, without thereby compromising the tactile quality appearance of its fibre fabric, the fabric is sprayed, all over or graphically confined, with gloss varnish before its laminating, according to invention.
The pigments, which thereby punctually-close precipitate on the course of the fibre surfaces of the fabric, are then thermally cured before the so-coloured fabric is laminated to tabular or continuous fibre composite material, as a raw material for a substantially thermally reshapeable object.
Closer to illustrate fibre composite material, dyed according to the invention, it is made to the following description of a preferred embodiment, outlined in the drawing.
In the single figure a greatly enlarged, and not to scale, broken section of a fibre composite ply 10 with single-ply fibre fabric 11 is sketched, whose warp and weft fibres 13 are here woven into a linen texture. The reinforcing fibres 13 are usually glass fibres, but also other materials such as aramid fibres can be tinted with brilliant colour appearance of the fabric structure according to invention, but with no impact on electrical functions. The fabric 11 was sprayed here with a coloured gloss, on one side. That made the fabric structure-following precipitation, here exaggeratedly discontinuously sketched, as brilliant as fine-grained color pigments 12 on the interwoven fibres 13.
With the glossy varnish it is preferably a matter of a sol-gel-hybrid coating system, as for example, it is used after evaporating the coating solvent in sprayed hydrolysis sol to a highly crosslinked clearcoat gel film as a decorative, scratch-resistant protective coating on glass surfaces, or as a dirt-repellent coating on sanitaryware. The sol is doped in the scope of the present invention, however, with very fine-grained and more colour-intensive pigments 12, which adhere well to the fibre surfaces in the final thermally lifted condensation of the sol to gel, following the fabric structure.
The bound on fabric 11 in the gel pigments 12 were kept in an infrared tunnel oven at a temperature of the order of about 180 degrees Celsius after brief drying, and then slowly cooled, to roughly stabilize the fibre surfaces while promoting the condensation reaction of the sol to the gel. This was typically followed by the at least one-sided, but usually two-sided lamination of the thus dyed fabric 11 to the fibre composite material 10 with a matrix 14, made of transparent or translucent plastic, such as polyamide or polypropylene, or polyurethane, that adhered well to the fabric 11.
The broadloom or sheets of the so e.g. custom coloured fibre composite material can be cut to specific product, for instance for thermal deep drawing to a high strength formed part, such as the very thin and flat, however, surface strip- and due to its superficial tissue structure haptically and visually-appealing battery cover or the similar radio and electronics acceptable flat housing shell of an electrical consumer device.

The broadloom or sheets of the so e.g. custom coloured fibre composite material can be cut to specific product, for instance for thermal deep drawing to a high strength formed part, such as the very thin and flat, however, surface strip- and due to its superficial tissue structure haptically and visually-appealing battery cover or the similar radio and electronics acceptable flat housing shell of an electrical consumer device.
Claims (10)
1. A method for producing a colored composite material (10) by spraying a fabric (11) or the fibers (13), before lamination of the fabric (11), with a paint, which is then thermally cured.
2. A method according to the preceding claim, characterized in that the fabric (11) is sprayed with a colour-pigmented gloss varnish.
3. A method according to one of the preceding claims, characterized in that the paint is sprayed onto the fabric (11) bounded graphically.
4. A method according to one of the preceding claims, characterized in that the sprayed pigments (12) of the varnish are burnt into the surfaces of the fibres (13) of the fabric (11).
5. A method according to one of the preceding claims, characterized in that the fabric (11) or even the not-yet woven fibres (13) are sprayed with so called porcelain colour of the type, with the use of colour pigments in the excess of solvents, as employed in particular for printing of articles made of glass or metal.
6. A method according to one of the preceding claims, characterized in that the fabric (11) or even the not-yet woven fibre (13) is sprayed with a coloured pigment-offsetting sol a sol-gel-lacquer system.
7. A fibre composite material (10), dyed according to any one of the preceding method, characterized in that the surfaces of the fibres (13) of its web (11) bear color pigments (12).
8. A fibre composite material according to the preceding claim, characterized by high gloss pigments (12).
9. A fibre composite material according to one of the two preceding claims, characterized in that the pigments (12) are burned into the fibre surfaces.
10. From a blank cut of the fibre composite material (10), according to one of the three preceding claims, a thermoformed flat, haptically appealing and custom-specific colourable forming part, in particular a housing shell of an electronic device, sporting goods or motor vehicle decorative element.
