Problems solved by technology

[0006] The proven known prior art solutions have the problem that the seam of the cover material is not fixed sufficiently and slippage occurs during the in-mold foaming step
In addition, it was found that the polyurethane barrier layer itself may lead to changes in the properties of the cover material

Embodiment Construction

[0055] Figures 1a to 1e A first example of the method according to the invention for producing a multilayer molded body is shown. Such as Figure 1a In particular, a self-supporting barrier layer 11 impermeable to foamed plastic, such as polyurethane foam, is first produced according to this example. The barrier layer 11 can thereby be formed, for example, from a foamed polyolefin or polystyrene film. As mentioned above, the self-supporting barrier layer 11 exhibits a specific shape corresponding to the outer contour of the molded body to be produced, as will be explained in more detail below. The molded body can be, for example, the outer contour of a dashboard, a door trim panel, a center console or other similar interior parts for a motor vehicle. In other words, the self-supporting barrier layer 11 is preformed before being introduced into the foam mould.

[0056] This preforming is performed, for example, by deep drawing the aforementioned polyolefin or polystyrene fi...

Abstract

The present invention relates to a method for producing multi-layered shaped bodies, in particular internal fitting parts for vehicles, in which a foamed plastic (25) is applied to a rear side of a cover material (14-1, 14-2), wherein firstly a self-supporting barrier layer (11) impenetrable to the foamed plastic (25) is produced. The application and fixation of the cover material with at least one partial region of the rear side thereof on the self-supporting barrier layer (11) forms a precomposite (17) between the barrier layer (11) and the cover material (14-1, 14-2), even before introduction into the foaming mould (20). This effectively prevents the cover material from slipping during the foam-backing.

Description

technical field [0001] The invention relates to a method for producing a multilayer molded body according to independent claim 1 . The invention also relates to a molded body which can be produced by the inventive method. Background technique [0002] Apart from the design of the bodywork which in most cases attracts the attention of onlookers first, the design of the car interior is also an important factor in the development of modern cars. It is not only the visual appearance of individual interior elements that is valued here; in fact, the interplay between the haptics and the materials, shapes and colors of the interior accessories also plays a crucial role. A high-quality car interior impresses primarily because of its design and carefully crafted materials. For example, automotive interior leather has long since ceased to be restricted to the high-end market and is increasingly found in mid-priced vehicles as well. The processing of a natural material, especially g...
