20. A method of forming a composite panel configured for use in a sidewall of a trailer, the method comprising:
-
forming an uncooled thermal plastic sheet of material; advancing the uncooled thermal plastic sheet of material through a transversing punch in order to form apertures through the uncooled thermal plastic sheet of material such that each aperture extends from an outer surface of the thermal plastic sheet of material to an inner surface of the thermal plastic sheet of material; cooling the transversing punch; and coupling an outer metal sheet and an inner metal sheet to the respective outer surface and the inner surface of the uncooled thermal plastic sheet of material.
