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.
