Definitions
- the invention relates to a sandwich component, in particular for the lightly exposed field of view of a motor vehicle, consisting of a specific light deviskem and at least on the visible side of the sandwich component load-resistant connected fiber composite cover layer, according to the preamble of patent claim 1.
- Sandwich components of this type are increasingly used because of their lightweight construction potential as lightly contaminated trim parts in visual, such as in the interior of motor vehicles and then have to meet strict weight and high optical quality requirements.
- the object of the invention is to provide a sandwich component of the type mentioned in such a way that with reduced weight and low cost, an optically high-quality, color-true design of the cover layer on the component view side is achieved.
- the inner core is thereby pre-dyed in the same color as the cover layer in a further production-related simplification, so that it is coated with a color layer, for example by way of the dipping method, or else it is laminated with a colored foil.
- the cover layer is also suitably initially cured for production reasons and then backfilled with the same color colored core material, so in particular backfoamed.
- Dark colored, translucent fiber composite cover layers eg. B. carbon fiber composite material
- thin-walled fiber composite cover layers with a transparent matrix but opaque fiber material can obtain a color image of the same color as the fiber material without color jumps at the light passages of the transparent fiber composite matrix.
- FIG. 1 shows a detail of an inventively designed sandwich component with a translucent cover layer and a precolored foam inner core in an enlarged scale
- FIG. 2 shows a partial section of a secondticiansbetspiels with a transparent fiber composite matrix and a color co-equal to the fiber material coated inner core.
- sandwich component 1 consists of a fiber composite cover layer 2, such as carbon fiber composite material, and a specific light inner core 3, z. B. of a polyurethane foam with a material in itself z. B. yellowish tint.
- cover layer 2 In load-appropriate design of the cover layer 2, this can be so thin-walled dimensioned that the core material through the cover layer 2 at least locally shines through and therefore falsifies the appearance of the cover layer 2 color.
- the same color pigments are added to the core material to the cover layer 2, so that the cover layer 2 can be made thin-walled translucent, yet the sandwich component 1 acquires a color-pure and structurally identical appearance to the cover layer 2.
- the cover layer 2 is first cured in this case for reasons of a production-related simplification and then foam-backed material with the pre-pigmented mecanicknma-.
- the Certainlykem 3 is covered on both sides with a fiber composite cover layer 2, which from a turn dark fiber material, ie about carbon fibers, but a transparent fiber composite matrix, eg , B. of epoxy resin, while the inner core 3 is made of a different color to the fiber material core material, so as yellowish tinted polyurethane foam, so that at Lastz thin-walled dimensioning of the cover layer 2 on the visible side of the sandwich component 1 a yellowish-dark speckled color impression can arise.
- a fiber composite cover layer 2 which from a turn dark fiber material, ie about carbon fibers, but a transparent fiber composite matrix, eg , B. of epoxy resin, while the inner core 3 is made of a different color to the fiber material core material, so as yellowish tinted polyurethane foam, so that at Lastz thin-walled dimensioning of the cover layer 2 on the visible side of the sandwich component 1 a yellowish-dark speckled color impression can arise.
- the schwkem 3 is completely over the entire surface before lamination of the cover layer 2, z. B. by way of dipping process, coated with a color material 4 to the same color as the fiber material of the cover layer 2. Therefore, the finished sandwich component 1 has on the cover layer side viewing surfaces a continuous uniform color design same color to the cover layer fibers and no color jumps at the light apertures of the transparent fiber composite matrix.
