Abstract
A molded structural-wood-fiber product is disclosed that is formed in three dimensions under conditions of heat and pressure. The molded product has the form of a single-piece wood-fiber web consisting of corrugations having indentations along the ridges of the corrugations on both sides of the web. Sheet facings may be applied to one or both sides of the fiber web to form a stiff, lightweight composite panel that has similar stiffness both along and across the corrugations. Several fiber webs or composite panels may be bonded together in stacked configurations to produce high-strength, light-weight panels, beams or platforms for heavy-duty applications. The unique structure of the three-dimensional fiber web permits straightforward high-speed manufacture using a rigid mold and one-dimensional pressing forces. Specific items that can be manufactured utilizing the fiber web and composite panels include pallets, bulk bins, heavy-duty boxes, shipping containers, wall panels, roof panels, cement forms, partitions, poster displays, reels, furniture, caskets, and doors.
