Procedure for obtaining a roof liner for a vehicle, comprising the following steps:
- a) joining a foam layer and a mat of plastic fibres using a first adhesive placed between said foam layer and said mat, to form a central core comprising said foam layer and said mat;
- b) joining a plurality of additional layers to the central core to form a layered product comprising said central core and said additional layers, joining at least one of said additional layers to the central core by a second adhesive;
- c) applying pressure to the layered product in a press to give it a predetermined configuration;
- wherein
- said second adhesive comprises a thermosetting adhesive;
- and wherein
- in step c) pressure and heat are applied in the press to produce a substantial polymerisation of the second adhesive.
Vehicle roof liner comprising:
- a central core comprising a foam layer and a mat of plastic fibres joined by a first adhesive placed between said foam layer and said mat;
- b) a plurality of additional layers joined to the central core, at least one of said additional layers being joined to the central core by a second adhesive;
- wherein
- said second adhesive comprises a thermosetting adhesive.
