Abstract
A cost-effective and resource-saving method for manufacturing a trim element, in particular a trim element which is used as a vehicle interior lining element. The trim element has a rear side reinforcement layer and a decorative surface. In the method according to the invention, a first layer is bonded in a first lamination step under pressure and heat to a first lamination and a second layer is bonded in a second lamination step under pressure and heat to a second lamination. The heat introduced in the second lamination step also acts in the first lamination and increases its bonding strength to the first layer.

A method for manufacturing a trim element with a rear side reinforcement layer and a face side decorative surface;
- in which a first layer is bonded under pressure and heat in a first lamination step to a first lamination for producing a substantially planar ply composite,
- in which a second layer is bonded under pressure and heat in a subsequent second lamination step to a second lamination,
- wherein in said subsequent second lamination step, the second layer is abutted against the first lamination and heat introduced in said second lamination step also acts on the first lamination, so that the second layer is bonded to the ply composite via the first lamination to produce a substantially planar sandwich structure,
- wherein the rear side reinforcement layer is formed by a fused arrangement of a plastic material against a rear side of the second layer and bonded to the second lamination,
- wherein the first lamination comprises a two-ply lamination having a first lamination face side ply and a first lamination rear side ply and the first layer is bonded to the first lamination face side ply abutted against the first layer;
- wherein the second lamination comprises a two-ply lamination having a second lamination face side ply and a second lamination rear side ply and the second layer is bonded to the second lamination face side ply abutted against the second layer, and in said subsequent second lamination step the second layer on the second layer's side facing the first layer is bonded to the first lamination rear side ply abutted against the second layer and on the second layer's side facing away from the first layer is bonded to the second lamination, and
- wherein the first lamination rear side ply and the second lamination face side ply are made of a first material that is the same and the first lamination face side ply and the second lamination rear side ply are made of a second material that is different than the first material.
A method for manufacturing a trim element having a face side decorative surface and a rear side reinforcement layer comprising the steps of:
- bonding a first layer under pressure and heat with a first lamination to a rear side surface of the first layer opposite the face side decorative surface, the first lamination comprises a first lamination face side ply comprising a fusing thermoplastic and a first lamination rear side ply comprising an activation cross-linking material, wherein the first lamination face side ply is bonded adjacent the rear side surface of the first layer and the first lamination rear side ply faces away from the first layer forming a first ply composite;
- treating the first ply composite with a subsequent treatment, whereby the first lamination reinforces and protects the first layer during the subsequent treatment;
- placing a second layer having a second layer face side surface and a second layer rear side surface with the second layer face side surface adjacent the first lamination rear side ply of the first layer, the second layer provided with a second lamination comprising an activation cross-linking material adjacent the second layer rear side surface;
- and
- bonding the second layer face side surface of the second layer under pressure and heat to the first lamination rear side ply forming a sandwich structure.
A method for manufacturing a trim element having a face side decorative surface and a rear side reinforcement layer comprising the steps of:
- bonding a first layer under pressure and heat with a first lamination to a rear side surface of the first layer opposite the face side decorative surface, the first lamination comprises a first lamination face side ply made of a fusing thermoplastic material and a first lamination rear side ply made of an activation cross-linking material wherein the first lamination face side ply is bonded adjacent the rear side surface of the first layer and the first lamination rear side ply faces away from the first layer forming a first ply composite;
- placing a second layer having a second layer face side surface and a second layer rear side surface with the second layer face side surface adjacent the first lamination rear side ply of the first layer, the second layer provided with a second lamination comprising an activation cross-linking material adjacent the second layer rear side surface;
- bonding the second layer face side surface of the second layer under pressure and heat to the first lamination rear side ply forming a sandwich structure;
- forming the sandwich structure into a desired contour of the trim element;
- and
- fusing a reinforcement layer to the second lamination.
