Description
- 1. Field of the Invention
- The invention relates to a compound motor vehicle component, especially a motor vehicle roof part, with an outside skin, an inside layer and a spacer part which contains hollow chambers, and which is located between the outside skin and the inside layer and is connected to them. The invention furthermore relates to a process for producing one such compound motor vehicle component and a molding tool for producing one such compound motor vehicle component.
- 2. Description of Related Art
- French Patent 1,113,551 discloses a roof part for a motor vehicle is produced by joining two layers with an interposed spacer part containing hollow cavities under the action of heat radiation or infrared radiation and compression in a molding tool to form a sandwich component. First, a release agent is applied to the molding tool, and then, an outside layer of a thermosetting resin is applied to the release agent. A layer of resin-impregnated glass fiber fabric is applied to this outside layer. Then, the honeycomb spacer part is applied, due to its flexibility, it adapts to the shape dictated by the molding tool. Finally, another layer of resin-impregnated glass fiber fabric completes the roof part which is set by the action of heat.
- A primary object of this invention is to create an easy-to-produce compound motor vehicle component of stable shape with very high surface quality, and to create a process and a device for producing the compound motor vehicle component.
- This object is achieved by a compound motor vehicle component in which the final, outer side of the compound component is formed by using a surface-finished component as the outside skin which is connected to the spacer part. Accordingly, the outside skin can be sheet metal which has been enameled in the desired color or a colored plastic.
- In particular, by pre-forming the outside skin, preferably by deep drawing, a very light, but still stable compound motor vehicle component is formed, especially a motor vehicle roof part, with an outside skin which can be produced in high precision and surface quality.
- Advantageously, a spacer part, as known from FR-A-1 113 551, which has webs which separate the hollow chambers and which extend essentially perpendicularly to the outside skin is used. In this way, an especially high stability of shape is achieved perpendicular to the direction of primary extension or in the vertical direction. Furthermore, the spacer part, advantageously, has a permeability to the liquid or foam adhesive due to the hollow chambers. By diffusing the adhesive into the glass fiber mats and towards the side walls of the webs, a very high inherent stability results and is at least equivalent to that of a sheet metal part. Heat treatment which may adversely affect the quality of the outside skin and which is required in the roof part described in FR-A-1 113 551 is not necessary for setting of the liquid or foam adhesive.
- By using a film, especially a thermoplastic film which can be deformed by deep drawing, almost any shape can be produced for a compound motor vehicle component in the corresponding molding tools. The thermoplastic film is preferably composed of a carrier layer which is formed, for example from ASA-PC (acrylonitrile-styrene acrylester polycarbonate) or from ASA-HDT (ASA with high thermal stability), an appearance layer of colored PMMA (polymethyl methacrylate) which adjoins it to the outside, and optionally, a protective layer of transparent PMMA which follows further to the outside.
- At least one additional layer which is formed by a glass fiber mat is preferably added to the outside skin and the spacer part. Here, a glass fiber mat is located on the side of the spacer part facing away from the outside skin. It is likewise joined to the spacer part by an adhesive which has been sprayed on.
- Optionally, to further stiffen the compound motor vehicle component, there is another glass fiber mat between the outside skin and the spacer part or reinforcing fibres with random orientation. The glass fiber mats preferably have a weight per unit of area of 300 to 400 grams per square meter and a thickness of roughly 0.3 millimeters.
- The adhesive is preferably polyurethane. It is used essentially to guarantee the connection between the inside layer and the spacer part or between the outside skin and the spacer part and its strength.
- The spacer part preferably contains a structure in honeycomb or corrugated shapes of cardboard, aluminum and plastic, for example, of polyamide or polyester.
- The outside skin overall has a thickness of for example 1-2 mm and preferably roughly 1.5 mm.
- A process in accordance with the invention for producing a compound motor vehicle component contains the following process steps:
- insertion of an outside skin, which acts as a carrier layer during the production process, into a first mold half of a mold;
- insertion of a glass fiber mat into the second mold half;
- application of an adhesive to the glass fiber mat in the second mold half and to the back side or inside of the outside skin in a first mold half or to the glass fiber mats on the bottom and/or top of the spacer part which is provided with hollow chambers;
- insertion of the spacer part between the two mold halves while the adhesive layers are still liquid or sticky;
- closing of the two mold halves with impression of the final shape;
- the first mold half can be a first mold half and the second mold half can be the second mold half; and
- diffusion of the adhesive into the spacer part and setting of the adhesive.
- To further increase stability, preferably the spacer part is provided with another glass fiber mat before placement on its surface which faces the inside of the outside skin.
- Adhesive can be applied, preferably by means of a spray or foaming tool which is guided by a robot, to the glass fiber mat in the second half of the mold and to the inside of the outside skin directly in the tool when the tool halves are still opened. Alternatively, it is also possible to also apply the adhesive outside the tool at least relative to the upper glass fiber mat. As another alternative, it is also possible for the adhesive to be sprayed or foamed outside the tool onto the top and bottom of the spacer part and for it to be inserted between the upper glass fiber mat which is already in the tool halves and the outside skin. Finally, as another alternative, prefixed glass fiber mats can be located on the top and bottom of the spacer part and sprayed or foamed in outside the molding tool with adhesive. The sprayed-in or foamed-in spacer part is then inserted between the tool halves and connected to the outside skin.
- As another process step, by means of a slider located in the tool, after setting, the edge area of the motor vehicle roof part which is used to hold the outside skin and the glass fiber mat is cut away.
- One mold tool which is especially suitable for producing the compound motor vehicle component, according to the invention, is formed by the first for example first half of the molding tool which is preformed to hold the outside skin of the compound motor vehicle component which is used as the carrier layer in the production process and has a slider which can be moved perpendicular to the direction of extension of the compound motor vehicle component and which is provided with centering pins for holding the outside skin and with an edging cutter, and by the second half of the molding tool which is provided with holding devices and/or projections to hold a glass fiber mat.
- In another embodiment, the second half of the molding tool has a slider which is provided with a groove for holding the centering pins and which has an opposite surface which yields upward opposite the edging cutter of the first mold tool half.
- Optionally, an additional spray or foaming tool for applying the adhesive between the opened mold halves is supported to be insertable on the frame of the molding tool. This spray tool is preferably guided by a robot arm. It has two sets of nozzles, of which one nozzle set is pointed up and the other nozzle set is pointed down.
- Embodiments of the invention are described below in greater detail with reference to the accompanying drawings.
- FIG. 1 shows a section through the edge area of a molding tool in the production of a first compound motor vehicle component, especially a motor vehicle roof part, in the opened state,
- FIG. 2 shows a section through the edge area of a molding tool in the production of a second compound motor vehicle component in the opened state, and
- FIG. 3 shows a section through the edge area of a molding tool in the closed state.
- A motor vehicle roof part1, which is prefabricated for cementing into a motor vehicle roof and which has an edge area which is shown in cross section in FIG. 3 in its complete structure, is composed of an
outside skin 2 which is used in the production process as a carrier layer, anadhesive layer 3 which is applied to its inside by spraying or foaming on (see, FIG. 1 or 2), aspacer part 4, anadhesive layer 9 and an upperglass fiber mat 10. - In the embodiment shown in FIG. 2, there is also a lower glass fiber mat11, which in the embodiment, is located on the bottom of the
spacer part 4. If herein, with reference to the motor vehicle roof part 1, “lower” and “upper” are used, this location indication relates to the positions shown in FIGS. 1 to 3 in the production process, while the installation position of the motor vehicle roof part 1 in the motor vehicle, for example, represents a position turned by 180°. - The
spacer part 4 is composed of a honeycomb structural part of cardboard, aluminum or plastic withvertical webs 5 and hollow chambers 6 which are located in between. The structural part can also be formed from corrugated layers, the corrugations forming thewebs 5. Since thin-walled material is used for thewebs 5, thespacer part 4 is very light. The hollow chambers 6 have openings or pores on their top and bottom which are permeable to the adhesive 3, 9 and which enable the adhesive to diffuse into the area of thewebs 5. - The molding tool which is used for production is composed of a
bottom tool half 13 with aslider 14 which can be moved perpendicular to the direction of extension of theoutside skin 2, and atop tool half 17 with aslider 19 which likewise can be moved perpendicular to the direction of extension of theoutside skin 2. - On the
slider 14 of thebottom tool half 13, there are several centeringpins 15 which are spaced apart from one another and which are used to hold theoutside skin 2 which has been inserted into thebottom tool half 13. Theoutside skin 2 can be formed into a shape which is specific to the respective motor vehicle roof part or it is formed into its final shape in the molding tool. - On the
top tool half 17, there are several holdingdevices 18 on the outside which are spaced apart from one another and which, in conjunction with theprojections 23 which are provided on theslider 19, are used to hold and center the topglass fiber mat 9. Furthermore, theprojections 23 are used in conjunction with agroove 20 which is located inwardly therefrom to center and hold the centering pins 15 when the tool halves 13, 17 close. Still further inward from thegroove 20, on thetop slider 19, there is anopposite surface 25 which adjoins theedge area 12 of theoutside skin 2 in the closed state of the tool (see, FIGS. 1 & 2). The inner edge of thesurface 25 on theslider 19 is opposite theedging cutter 16 which is provided on the inside edge of theslider 14. Thebottom tool half 13 has a receivingspace 24 for theprojections 23 of thetop tool 19 when viewed from the centering pins 15 toward the outside. - The
upper slider 19 is movably guided in theguide chamber 22 of theupper tool 17. Thestop surface 21, which is provided on the back of a widened head of theslider 19, limits the motion of theslider 10 in conjunction with the bottom of theguide chamber 22. - After inserting the
outside skin 2 into thebottom tool half 13 and the upperglass fiber mat 10 into thetop tool half 17, by means of aspray tool 26 which has been inserted between the opened tool halves and which has aspray head 27 with a set of nozzles, 28 which are pointed downward and a set ofnozzles 29 which are pointed upward, adhesive 3 is sprayed onto the inside of theoutside skin 2 and adhesive 9 is sprayed or foamed onto the bottom of the upperglass fiber mat 10. Preferably, polyurethane or polyurethane foam is used as the adhesive 9. It has a setting time of roughly 30 seconds. As long as the polyurethane or polyurethane foam is still liquid, thespacer part 4 is inserted between the openedtool halves outside skin 2, which inside is arched in the manner of a trough and is bounded by theedge area 12 which is bent at right angles to the top. - Alternatively to the application of the adhesive3, 9 in the tool, it is likewise possible to apply the adhesive to the inside of the upper
glass fiber mat 10 and/or to the inside of theoutside skin 2 outside of the tool, then insert it/them into the tool, and then, insert thespacer part 4. As another alternative thespacer part 4 can also be sprayed with adhesive 3, 9 on its top and bottom outside of the tool, and then placed on the inside of theoutside skin 2 in thelower tool half 13. - According to another alternative, the
spacer part 4 can be provided with a glass fiber mat on its top and/or bottom which has been fixed there beforehand and onto which the adhesive is sprayed, and which, in the still liquid state of the adhesive, can be placed in the opened molding tool halves. - When the tool is closed, first the
bottom tool half 13 and thetop tool half 17 are moved towards one another. In doing so, the centering pins 15 are held by thegroove 20 and theprojections 23 are held by the receivingspace 24. Theoutside area 12 of theouter skin 2 is pressed securely against theopposite surface 25 by theslider 14. In this state, with the tool closed (FIG. 3), the stillliquid adhesive 3 diffuses into the cavities of thespacer part 4 and connects the connecting areas of thewebs 5 to theglass fiber mat 10, 11 there, as shown in FIG. 3. In this way, thespacer part 4 achieves very high inherent stability with very low weight at the same time. The adhesive 3, 9 is also applied to the inside part of theedge area 12, in the region of the edge of theoutside skin 2 which has been bent at right angles, so that theoutside skin 2 is joined peripherally to the topglass fiber mat 10 in this area in a watertight manner. - After setting of the adhesive3, 9, in another step, the
lower slider 14 and theupper slider 19 are moved inward toward each other, theedging cutter 16 cutting off theedge area 12. The finished motor vehicle roof part can now be removed from thelower tool half 13 after the tool halves 13, 17 are moved apart. Since the completely prefabricated outsideskin 2 is made of thermoplastic next to a carrier layer of polycarbonate, an appearance layer of PMMA which has been colored in the color of the motor vehicle which follows to the outside, optionally, with the addition of a protective layer of transparent PMMA applied to the outside of the appearance layer, the motor vehicle roof part is already in the ready-to-use state and can be inserted into the motor vehicle by cementing, for example, after delivery at the motor vehicle manufacturer to the installation line. - Since the
outer skin 2 has a thickness of only roughly 1.5 mm, thespacer part 4 is formed of very light, thin-walled material and also theglass fiber mats 10, 11 and theadhesive layers - The compound motor vehicle part can also be formed as a trunk lid or as another flat motor vehicle part.
