A method of producing a composite panel is described. The method includes the steps of (a) placing a veneer in a mold, (b) dispensing an expandable foam onto the veneer in the mold; (c) placing a cover over the expandable foam in the mold, wherein the cover is placed over the expandable foam prior to the foam expanding; and (d) allowing the foam to expand in the mold. The expansion of the foam is restricted by the closed mold to produce a composite panel containing expanded foam layer having a density of at least 6 pounds/ft.sup.3.

The embodiments of the present invention further provide a preparation method of the ceramic resin composite housing, and a terminal including the composite housing.

A method of manufacturing a co-molded housing component for an electronic device is disclosed. A component formed from a ceramic material is placed in a mold. The mold comprises a first section defining a first cavity configured to receive the first component, and a second section defining a second cavity that is in communication with the first cavity when the mold is closed. The second cavity is in the shape of a feature that is to be joined to the ceramic material. A polymer material is injected into the second cavity, thereby forming the feature from the polymer material and bonding the feature to the ceramic material. The polymer material is cured. The first component and the feature together form the housing component for an electronic device.
