<p>A method for producing three dimensionally contoured parts, particularly for automobile headliners, utilises a stiff thermoformable polystyrene foam core (10) to either side of which is laminated a porous, nonextendable rigidifying material (20,20a) and a fabric material (30,30a). The porous, nonextendable rigidifying material is arranged so as to be subjected to two dimensional contouring but so as not to extend into areas of the laminate which will be subject to severe three dimensional contouring.</p> |
