Abstract
The invention relates to a method for producing a composite part, in particular an internal paneling part for vehicles, having a multipart cover layer, and a composite part.
Claims19
A method for manufacturing a composite part to be used as an inner trim with a multipart cover layer from at least one first and at least one second skin, which in each case have a front side and a rear side, and with a foam layer which is connected to the cover layer on the rear side, comprising:
- arranging the first and the second skin in each case with an angled end section on the surface of a tool, in a manner such that the angled end sections of the first and second skin are directed away from the surface and are adjacent, wherein the end section of the first skin on the front side has a channel-like structuring;
- applying a vacuum in the region of the position of the angled end sections, so that the front sides of the angled end sections are pressed on one another in a sealing manner and on account of the structuring at least one channel structure is formed between the front sides of the angled end sections, which is accessible from the side of the first and second skin, said side being away from the vacuum;
- and
- back-foaming the first and second skin with a foam mass, wherein the foam mass enters into the channel structure and collapses and cross-links.
1 more element
A composite part comprising:
- a multi-part cover layer of at least one first and a second skin, which in each case have a front side and a rear side, and with a foam layer which is connected to the cover layer on the rear side, wherein the first and the second skin in each case have an angled end section and are arranged to one another in a manner such that the angled end sections along a separation line project into the foam layer and are in contact with one another with their front sides, wherein at least the end section of the first skin, said end section projecting into the foam layer, comprises at least one channel-like structuring, so that a channel structure which is accessible from the foam layer, is formed between the front sides of the end sections, said front sides being in contact, and the channel structure comprises cross-linked foam raw material.
