Abstract

Discloses skin and interior core structures made shape-adjustable with a layer of skin core forming a pre-molded perimeter rail; exterior structural skin can be molded using a convex shape-defining mold to produce a plurality of different shapes; separate subparts give the mold the capacity to describe different curves and modify different parameters of the board'"'"'s design. Mold is reversible; male/female configurations produce convex shape-defining substrates allowing a wide array of different shapes. Board is fabricated without use of any concave shape-defining surface, and therefore without the high manufacturing costs and structural problems of prior art female molds.
