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

MetEod for producing a coloured fihre-reitiibreed plastic and cham.ferig of such fibrereinforced plastic, as well as forming the part produced therefrom The invention relates to a mcthod for producing a coloured fIbre-reinforced plastic and a colored fibre-reinforced plastic as a primary material as a reshaped part, as it is lonned for example as part of a sporl.s product, as a decorative element in the interior of passenger cars of soph.islicated eqLLipllient or as a battery cover or oI.her 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 ate olien placed in practice. In particu.i.ar, despite its extremely flat formation, it should be an. extraordinarily flexible and torsion-resistart material with a pleasing appearance and with excellent feel, however, with low material and production costs.
The exterior is outfItted with a definable coloring, hut 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 hut more specific interpreted patterns.
In the presen.t case to simplify the representa:tion, it is always spoken oniy 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, serim, fiber strands (rovings), felts arid 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 prefened fibre-reinforced plastic, possibly also to a so-called organic sheets.
Especially with increased mechanical requirements for fibre-reinforced thermoplastic Thrmed parts, it is close Lu resorting to the fibre-rein bi-cement of carbon fibers. They exhibit not only very high strength, as a. formed part Lhcir 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 he used in. devices such as,for exarnpJ.e, mobile pl-iones, where an antenna is integrated. This deficiency in poor insulation for electronic applications is not found in the also very solid Kcvlar 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 rccoursc to thermoplastic laminates with the conventional glass fibre reinforcing labries, in particular the ones with layers, which also show very good mechanical strength. However, Ihe 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 [or use in higher-priced consumer goods. The individual glass fibers cannot he 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 virtual]y 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., he one drying pahtt 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 haptie 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.
In recognition of such situations, however, the present invention is undermined by the technical problem, that with a glass fibre reinforced formed part without appreciably altering tactile qualities and the visual appearance to its fibre structure that appear in different preset colours and with this in particular. to let those in the higher, gray-black caj-bon highlights shine out.
This task is achieved by the essential characteristics indicated by the respective principal claim. Thereafter either the not yet woven fibre, particularly conhiliL.Lous fibers, or -preferably -th.e fibre fabric of thc later composite material will be sprayed with a colour-pigmented coating, such as the one, that is also referred to as china colour, to finishing brilliant-coloured items of glass or metal, by using it to print on scratch resistant surfaces. The selectively relatively densely attained precipitate on the fabric side or both sides, cg custom coloured, is then thermally fixed in the manner of lacquer curing before the mat i.s laminated transparently or translucently in a conventional manner. The requirement. of a metallic sheen vapor deposition of paint applied (as in. i.he conventiuiial colour-diving) is omitted for this spiay colouring.
Such one-or two-sided spray application of lacquer with colour pigments in the solvent excess does not result in the effectively closed paint application of the surface, hut rathcr a more or less dense predeterniinable along the structure of the fabric surface adherng punctua.1 precipitation of the colour pigments, without flattening the structural fabric bumps. When viewing the fibre composite material with lhbric previously sprayed in this way. in particular in the incidence of light thereon, in the interior of the composite material absorption does not occur on likc a dipping leveled and matt coloured surface, and no surface reflection on a weakly wavy and shiny post-metallisation surface; but according to the intensity of the sprayed coating and the brilliance of its sense of the colour pigments scatter radiated light from a plui-ality of point light sources of the surfaces out of the individual libres from the inside of the laminated fabric structure This yields, without metallic vapor deposition, the desired brilliantly coloured shine effect, and while maintaining the visual and tactile properties of the fabric structure of its latter composite material fomied part.
This allows forming parts made of composite materials to be achieved, even with the inexpensive fiberglass fabrics available in a variety of brilliant colours and colour combinations, while maintaining a significant fabric structure. For manufacturing, the fabric is withdrawn from a supply reel and led through a. single or double acting spraybooth spraying with pigments with the solvent excess, and then for example through a tLlnncl oven, as found for lacquer curing in industrial applications, in finally be coiled as the brilliantly colored fabric web again, without impairment to the appearance of their fabric structure.
If the spraying of (lie coloured precipitate is not on such a large area as in an automalic spray cabin or, for example, with a spray gun, bul graphically specifically hounded by a nozzle aproximately like the type ol'print writing head system of ink jet printers, then for example, also multicolored ornaments, logos or labels can be applied to the still uncoated fabric, that are laminated by transparently or translucently, and thus they appear more structured and haptically highcrgrade in any colour combinations succinctly after the formation of the object of utility.
To colour a lightweight high performance fibre coinposil.e material that serves as a fibre-reinforced primary material for thcrmoforming ftnmed part, that is without mctalisation 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 pi.tnetually-close precipitate on the course of thc 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 rcshapeable object.
Closer to ill usirate 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. l'he reinforcing fibres 1 3 are usually glass fibres, hut also other materials such as ararnid fibres can be tinted with brilliant colour appearance of the fabric, structure according to invention, hut 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 discontinLtously sketched, as brilliant as fine-grained color pigments 12 on the interwov en 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 he coating solvent in sprayed hydrolysis sol to a highly erosslinked elearcoat gel film as a decorative, scratch-resistant protective coating on glass surfaces, or as a dirt-repellent coating on. saniLryware. The sol is doped in the scope of the present invention, however, with very fine-grained and more colour-intensive pignients 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 temperal.ure of the order of about iSO degrees Celsius after brief drying, and then slowly cooled, to roughly stabilize the fibre surfaces while promoting the condensation reaction of' lie sol to the gel. This was ypica1ly followed by the at least one-sided, but usually k 0-sided lamination of the tELLs dyed fabric 11 to the fibre eoniposite material 10 with a matrix 14, made of transparent or translucent plastic, such as polyamide or polypropylene, or polyurethane, that adhered we! 1 to the fabric 1. 1 The broadloom or sheets of the so e.g. custom coloured fibre composite material can he cut to specific product, for instance for thermal deep drawing to a high strength formed part, such as the very thin and fiat, however, surface strip-and due to its superficial. lissue structure haptieally and visually-appealing battery cover or the similar radio and electronics acceptable fiat housin.g shell of an electrical consumer device.
