Method of highstrength sandwich skin fabrication uses the thickness of a highdensity foam skin core (27) to mask minor imperfections on the surface of the mold, thereby allowing the mold (10, 20) to be divided into separate integral parts that have the capacity to be moved, then fixed and set, so as to describe different curves or modify dimensions of the board. Mold is reversible; malefemale configurations permit fabrication of a wide array of custom designs. Method offers low production costs due to a rapid mold cycle, reduced labor, and efficient use of space, yet produces an exceptionally high strength, light weight board because of the increased shear strength of the monocoque perimeter rail (70), and the optimum fiberresin ratio in the cored, structural sandwich skin. |
