ABSTRACT:
Disclosed is a manner of making a core by shearing and bending a strip (36) of sheet metal into ribbons. The ribbons thereby constitute a series of troughs (53) and crests (52). The core is sandwiched between two skins (64,65). The crest and troughs are presented as tubes (66) extending into the interior of the core from an edge of the panel. Polyurethane foam is injected into these tubes. The foam rises and sticks the cores to the skins. The resulting panel is strong, rigid, durable, inexpensive, and extremely versatile.
