A generally planar composite panel structure including (a) a stratified, generally planar main body core having perimetral edges, and spaced, generally planar, outwardly facing facial expanses extending substantially to such edges, and (b) in a stacked arrangement within the core, 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 core's perimetral edges.
