Method of making multilayer product having honeycomb core of improved strength

摘要

A process of making a multilayered product having an interior honeycomb layer or core. The interior layer is formed by extruding a generally corrugated web of material. The corrugated web is cut and folded to create the honeycomb core. Outer protective skins are applied to exterior surfaces of the interior layer to create a multilayered material which is then cut to size.
