Description

Surface with a wavy appearance

In accordance with the first item of claim 1, the invention relates to a planar member having a corrugated appearance surface and a method of making same, such as a wall, floor or trim panel.

The appearance of "corrugation" or the so-called corrugated vision is particularly popular in the decorative field of metal objects. Therefore, there is also a desire to stimulate the development of this appearance. On the basis of material replacement, the metal materials used conventionally are lighter than metals, easy to produce, and have different mechanical and physical properties. Such panels should also have better chemical resistance and a "pleasant" appearance and/or appeal, where appropriate.

Accordingly, it is an object of the present invention to provide a planar member such as a wall, floor or trim panel that exhibits a corrugated appearance surface and a method of making same.

This concept is used for flat parts such as walls, floors or decking in accordance with the wording of item 1 of the request and the method of item 6 of the claim.

The member of the present invention comprises, at least on its surface, a plurality of non-planar fibrous layers arranged substantially parallel to each other, the solidification system utilizing a polymerization The material is simply cut flat and individually ground to create the surface.

In one embodiment, it is provided that at least the mutually adjacent fiber layers are undulating, and the fiberboard surface is planarly cut to produce the planar member, such as a flat sheet having a corrugated appearance on the surface. Taking the use of a unidirectional fiber layer as an example, such as a carbon fiber layer, the appearance of the waveform is formed by bevel cutting of fiber layers having different orientations. Due to the directional reflection properties of the fibers, such as carbon fibers, the illumination of the inclined layers is different under illumination, and the desired moiré pattern is formed. There are also other fiber types, such as glass fiber or synthetic fiber, which can initiate the corrugation effect, and both thermosetting and thermoplastic plastics can be used as a matrix for the solidification of the layers. The optimum optical properties of the material are achieved in a pure, transparent or translucent matrix material, so that in thermosetting materials, for example, epoxy resins, polyester resins, vinyl ester resins are useful. In thermoplastics, for example, PEEK, PEI, polyamide 6 and 66, polyamide 11 or 12, PBT, PET, PP, HDPE, PC or PMMA can also be used.

For the preparation of the member of the present invention, such as a plate having a corrugated appearance surface, first, in a wave shape, the deposition of a plurality of fiber layers substantially superimposed on each one or the other is laid out. Plane and insert into the mold of the corresponding shape. Thereafter, the fibrous layers are immersed in the liquid polymeric material and finally solidified, for example, by compression.

The resulting structure is then removed from the mold and at least one surface is flat cut, ground and polished to form a panel having a smooth, flat surface with a corrugated appearance or trace.

In one embodiment, a thin unidirectional fiber layer is used, such as The carbon fiber layer is used to solidify half of the transparent matrix material, such as a thermosetting duromer or thermoplastic, preferably it is colorless, transparent or translucent.

After the curing process of the colloid or the cutting of the thermoplastic solidified body, the layers are ground and polished to form the smooth flat surface having a corrugated appearance.

The invention will now be explained in more detail by way of examples and with reference to the accompanying drawings.

The fiber layer in the first step in Fig. 1 has been undulated in the mold; in Fig. 2, the separately cured fiber layer in the mold is ready for cutting; the third figure is cut. The fibrous layer has a flat, smooth surface; and Figure 4 is a top view of the corrugated appearance of the surface of the planar member prepared in accordance with the working flow of Figures 1-3.

Fig. 1 shows the invention in a schematic and longitudinal section, and is inserted through a compression mold 1 in which a plurality of fibrous layers 5 are placed, which are laid, for example, in a wavelike manner. In order to create the wave shape, for example, the lower mold portion 3 of the mold can be formed in a wave shape, and the cover plate 7 is correspondingly adjusted. It is to be understood that this wave shaping is only one of the possible embodiments. However, it is important that each layer is not laid out in a plane, but has protrusions that protrude upward and downward. Non-planar. For example, during the insertion of the layer 5 in the mold 1, by using a thermosetting material as an example, such as an epoxy resin, a polyester resin or a vinyl ester resin, they are impregnated for later in the mold. Cured and optionally pressed. Instead of a thermoplastic polymer, thermoset plastics may be used again, such as PEEK, PEI, polyamide 6 or 66, polyamido 11 or 12, PBT, PET, PP or HDPE, to name a few. Here, the processing process will of course present a state in which the thermoplastic material is attached to the fiber, for example, in the form of the prepreg, and the plurality of layers located therein are solidified by exposure to pressure and temperature. If a pure, transparent or translucent matrix material is used as the polymer, it is advantageous to make the wavy plate and the prepreg as shown in Fig. 1. For example, unidirectional carbon fiber, glass or other synthetic fibers can also be used as the fiber layer.

After pressing and curing, the wavy plate or the prepreg is removed from the mold for subsequent planar cutting and grinding, as shown schematically in FIG. Therefore, the cutting or grinding is performed along the broken lines 11, 13.

Finally, in order to produce the panel of the present invention, the cut and ground semi-finished product can be transferred to, for example, the substrate 19, however this is not essential. Importantly, in the following, the surface 17 of the semi-finished plate 15 is placed flat on the ground to produce the desired corrugated pattern due to exposure of different light of the inclined layers.

Fig. 4 is a view showing a corresponding upper view of the plate body 15 shown in the longitudinal section of Fig. 3. Therefore, in the inclination angle of the fiber layers in different orientations, the appearance of the corrugation produced can be clearly recognized.

The orientation of the fibers, the density and thickness of the layers, and the shape of the waves of the wave making tool can significantly affect the optics. The corrugated optics can also be used in three-dimensional structures. Therefore, the contour of the pressing should be modified in advance according to the appearance to achieve the final geometry.

A simple corrugated optics is effective, for example, by a unidirectional carbon fiber prepreg. When a prepreg from glass fiber, synthetic fiber or both is combined with a carbon fiber prepreg, additional effects can be obtained, for example, due to the color effect of the colored fiber or the illuminating effect from the embedded fiber. In particular, additional lighting effects can be achieved by the use of light conductors.

In the member of the present invention, the plate body is taken as an example and can be used in various applications. For example, for floor, wall layout, as artwork for painting, for interior decoration, for interior design (building, shipbuilding, automobile manufacturing), for exterior cladding, for table tops, countertops, The furniture of the cooktop is manufactured as an overcoating process.

In addition, in the lighting technology and design, according to the design presented and presented, it can be used in the manufacture of sports equipment, and in the covering process and packaging process of electronic equipment.

It is of course also possible to separately produce a foil film which can be applied to the three-dimensional structure/component by thermal properties.

Special properties such as scratch resistance, toughness, chemical resistance, heat resistance and UV resistance can be obtained by appropriate selection of the base material.

The method of manufacture illustrated in Figures 1-4, which are referred to, is of course merely exemplary in nature to better illustrate the invention. The invention by making Using a plurality of non-planar adjacent fiber layers which are bonded by a polymer matrix material and which are finally subjected to substantially planar cutting and at least grounding operations on a surface, the invention need not be limited to the plate body The production of the film and the coating of the substrate can also be carried out.
