A vehicle inner panel with a padded fabric surface, and includes firstly moulding a substrate of polymeric material, suitably polyurethane, attaching the substrate to one die of a two part die set, stretching a fabric sheet on a stretch frame, interposing the stretched fabric sheet between the other die of the die set and the substrate, injecting foam forming polyurethane through the substrate and allowing it to foam while the dies are closed, opening the dies, removing the assembly, and trimming the fabric.

A method of forming a vehicle inner panel, comprising: (a) moulding a substrate of polymeric material, (b) attaching the substrate to a first die part of a two-part die set, (c) attaching peripheral edges of a sheet of stretchable fabric to a peripheral frame surrounding and free from the die set, whereby the fabric is freely held with respect to the die set, and interposing the freely held fabric sheet between the substrate and a second die part of the die set, (d) closing the first die part to the second die part to bring the substrate into juxtaposition with the fabric sheet, and also to deform the fabric sheet to the shape of the substrate, (e) injecting foam-forming polymeric material through the substrate to lie between the substrate and the fabric sheet, and allowing the polymeric material to foam and at least partly set while the die parts remain closed to stretch the fabric sheet and to maintain the fabric sheet in stretched condition over the foamed polymeric material, and (f) opening the die parts, and removing the assembly of substrate, foam and fabric from the die parts and from the frame.
