1. A multilayer laminate panel, comprising:
a first layer of a stone-based material;
at least one layer of a dissimilar material of a lower density than a density of the first layer of the stone-based material;
a first layer of resin-impregnated fibers interposed between the first layer of the stone-based material and the at least one layer of a dissimilar material; and
a second layer of the resin-impregnated fibers disposed on a surface of the first layer of the stone-based material that is located on an opposite side of another surface of the first layer of the stone-based material on which the first layer of the resin-impregnated fibers is disposed,
wherein the panel is configured such that the first layer of the stone-based material is under compression when the panel is mechanically loaded and supported on two or more anchoring points,
wherein the dissimilar material comprises cork or a derivative of cork,
wherein a thickness of the layer of stone-based material is from about 2 mm to about 50 mm, and
wherein a location of a neutral axis of the panel is located outside the first layer of the stone-based material and outside the first layer of the resin-impregnated fibers and the second layer of the resin-impregnated fibers, and is located in the at least one layer of the dissimilar material.
