Abstract

A method of forming a composite panel in-line is disclosed. The method includes the steps of forming a hot thermal plastic sheet of material and providing the hot thermal plastic sheet of material to a punch having punch members extending outwardly therefrom. The hot thermal plastic sheet of material is advanced through the punch in order to form apertures through the hot thermal plastic sheet of material such that each aperture extends from an outer surface of the hot thermal plastic sheet of material to an inner surface of the hot thermal plastic sheet of material. An outer metal sheet and an inner metal sheet, respectively, are coupled to opposing sides of the hot thermal plastic sheet of material.
