Abstract
A multilayer laminate panel comprising a first layer of a stone-based material and a second layer of a dissimilar material of lower density, which are interposed by one or more layers of resin-impregnated fibers, is provided. The dissimilar material comprises cork or a derivative of cork, and the thickness of the layer of stone-based material is from about 2 mm to about 50 mm. A process for the production of the panel is also provided. The panel finds use as a coating in a variety of interior and exterior applications. A panel comprising fixing means and a process for attaching the fixing means to the panel are also provided.
Claims20
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.
A multilayer laminate panel, comprising:
- a first layer of stone-based material, having a thickness from 2 mm to 50 mm, being stone or a stone derivative, and configured to be under compression when the panel is mechanically loaded from an exposed surface of the first layer and supported on two or more anchoring points;
- a second layer of dissimilar material having a lower density than a density of the first layer, the second layer comprising cork or a derivative of cork, and having a thickness from 1 mm to 50 mm;
- and
- at least two layers of resin impregnated fibers,
- wherein a first fiber layer is positioned at an interface between the stone or the derivate stone material and the cork or the cork derivate layer,
- wherein a second fiber layer is positioned on an exterior surface of the cork or the cork derivate layer,
- wherein a resin is provided by fiber-containing reinforcement layers to attach layers of the multilayer laminate panel together to form a unitary panel structure,
- wherein the panel has a maximum load at rupture of at least 20 times as compared to a same stone thickness, measured in accordance with ASTM C293,
- wherein the first fiber layer is a multiaxial reinforcement fabric including glass fibers with a specific mass between 150 g/m2 and 300 g/m2 per orientation axis, and
- wherein the second fiber layer comprises a woven fabric with a specific mass between 150 g/m2 and 400 g/m2.
