ABSTRACT:
A laminated panel construction comprises a base panel preferably comprising a propylene polymer and a filler, a non-woven fabric mechanically anchored to a surface of the base panel and a thermoplastic foil secured to the non-woven fabric by an adhesive material. The non-woven fabric is secured to the surface of the base panel by pressing the base panel and non-woven fabric together at elevated heat and pressure. The base panel with the non-woven fabric secured thereto may be shaped into a predetermined configuration before the thermoplastic foil is adhesively bonded to the non-woven fabric.
