COMPOSITE PANEL STRUCTURE FOR MOTOR VEHICLES AND THE LIKE MADE OF NATURAL FIBRES AND THERMOPLASTIC SYNTHETIC FIBRES

The present invention relates to a polyfunctional self-supporting panel structure (30) for use in the passenger compartment of a motor vehicle, particularly for lining internal parts of the passenger compartment of a motor vehicle or for providing a frame for the upholstery of a motor vehicle or an accessory for the seats of a motor vehicle and the like. Such panel structure (30) comprises: at least one first panel (10), which is shaped and made of natural fibres and polypropylene and other synthetic thermoplastic fibres; in said at least one first panel (10) there being defined a first face (10a) and one second face (10b) juxtaposed to the first face (10a); and at least one second panel (20), which is shaped and made of natural fibres and polypropylene or other thermoplastic synthetic fibres; in said at least one second panel (20) there being defined a third face (20a) and a fourth face (20b) juxtaposed to the third face (20a); said at least one second panel (20) comprising at least one portion shaped so as to form, at the fourth face (20b), at least one protuberance (26, 27) carrying connection means (28, 29) so as to allow to connect, in use, said at least one second panel (20) to a support component of a motor vehicle; Furthermore, the at least one first panel (10) and the at least one second panel (20) are mutually joined at at least one respective peripheral area and/or at least one respective inner area so that the first face (10a) and the third face (20a) face each other, and that the second face (10b) is directed, in use, towards the internal of the passenger compartment of a motor vehicle, and that the fourth face (20b) faces said support component of the motor vehicle.
