Formed panel structure

Abstract

A generally planar composite panel structure including (a) a generally planar main body having perimetral edges, and spaced, generally planar, outwardly facing facial expanses extending substantially to such edges, and (b) within the main body, intermediate the mentioned facial expanses, at least one high-density, generally planar, fibre-reinforced layer structure bracketed by a pair of low-density, generally planar layer structures, each of which layer structures extends substantially to the main-body's perimetral edges.
