Abstract
A corrugated metal-clad sandwich panel with a wafer composite core is provided. The single stage process for the panel manufacture involves utilizing a press platen system which is mechanically convertible between a planar and a corrugated configuration. The metal sheet is first placed on the lower platen which is in the planar configuration. The wafers and an isocyanate resin in admixture are uniformly distributed over the metal sheet. Optionally, a second metal sheet is placed over the wafer/resin mat. The platens are biased together to precompress the mat. Finally, the platens are converted from the planar to the corrugated configuration, thus forming the corrugated metal-clad sandwich panel having a waferboard core in a single stage.
