Process for the production of a composite part with multi-part outer layer, and composite part

摘要

The invention relates to a process for the production of a composite part with a multi-part outer layer and with a foam layer bonded on the reverse side to the outer layer, in particular internal cladding of a vehicle, and also to a composite part. The inventive process comprises the following steps: a) arrangement of a first skin and of a second skin with angled-off end regions on the surface of a mold in such a way that the angled-off end regions of the first and second skin have firstly been oriented away from the surface of the mold and secondly are adjacent to one another; b) application of a reduced pressure in the region of the position of the angled-off end regions, in such a way that the angled-off end regions are pressed two-dimensionally against one another; c) reverse-side foaming of the first and second skin with a foam composition. The inventive process permits the simple production of visually attractive composite parts with multi-part outer layer.

主权项

1. A method for production of a composite part, in particular an interior trim, with a multipart cover layer and a foam layer which is connected to the cover layer on a rear-side, containing the steps:
a) arrangement of a first skin and of a second skin with angled-off end regions on a surface of a tool in such a manner that the angled-off end regions of the first and second skin are directed, on the one hand, away from the surface of the tool and, on the other hand, are adjacent to each other, wherein at least the first skin is configured in the end region thereof with one or more sealing lips integral with the first skin, and the at least one sealing lip is orientated, during arrangement of the first skin in the tool, towards the end region of the second skin; b) application of a low pressure in the region of the position of the angled-off end regions so that the angled-off end regions are pressed against each other flatly, where the low pressure is a partial vacuum; and c) rear-foaming of the first and second skin with a foam material while applying the low pressure.
