ABSTRACT OF THE DISCLOSURE An automotive ceiling panel and a process for manu- facturing the same and more particularly, to a process which reduces the weight of the panel and the man-hours required for the manufacture thereof and yet results in an improvement in the quality of the panel. The ceiling panel comprises a laminate of a first polyethylene foam layer having an aesthetically de- signed crimp-pattern in its layer surface, a second metal lath laid under the first polyethylene foam layer, and a third layer of polyethylene foam laid under the metal lath. The metal lath is sandwiched between the polyethylene foam layers, with the crimp-pattern appearing on the top surface of the panel. A process of manufacturing the automotive ceiling panel comprises the steps of forming a crimp-pattern in the surface of a first polyethylene foam layer by a crimp-pattern forming machine, placing a metal lath between the first and a second polyethylene foam layer, with the crimp-pattern carrying surface of the first polyethylene foam layer appearing on the top surface of the first layer, bodning the thus laid layers together using fusion-bonding and rolling techniques, and cold-pressing the laminate thus pre- pared into a desired shape for an automotive ceiling.
