Abstract
The present invention relates to a vehicle headliner and a method of manufacturing the same, in which a substrate is pre-molded into the shape of a headliner, and then rigid or semi-rigid polyurethane is partially foam-molded on a surface of the molded substrate to match the shape and thickness of the headliner, and thus the manufacturing process can be simplified while unintended buzz, squeak and rattle (BSR) and weight can be reduced.
Claims8
A method of manufacturing a vehicle headliner, comprising:
- forming a substrate (110) including a surface material (110′) and a glass fiber mat (110″) adhered with an adhesive (111) in a shape of a headliner;
- partially and repeatedly foam-molding a rigid or semi-rigid polyurethane (120) having a density of 10 to 40 kg/m3 on an entire surface of the glass fiber mat (110″) to match the shape and thickness having a tolerance between the headliner and a roof panel when the headliner is mounted on the roof panel so as to form a single piece:
- and
- attaching a non-woven fabric (130) to a surface of the polyurethane (120).
