Definitions

  • the present invention relates to a thin composite panel formed by a slab of stone material combined with a reinforcing element.
  • natural stone is regarded as being the most highly valued cladding material. Slabs of natural stone with large thicknesses - usually 20-30 mm or more - are used, in order to compensate for the fragility of stone which is due to its low mechanical strength and its inherent fissures.
  • the said reinforcement applied to the rear face increases considerably the maximum breaking load on this face so that if loads are applied on the opposite face of the reinforced slab (namely on the visible face), the slab flexes, generating a concavity which is directed towards the visible surface which is therefore compressed, while the rear surface - where the matting is applied - is tensioned. Since the fibre matting reinforcement impregnated with resins has a considerable capacity to withstand tensile stresses, the slab of stone material thus reinforced manages to withstand extremely well the loads applied to the visible face.
  • the glass fibre matting may be prone to peeling since, along the sides and in particular the corners of the product, for the most varied reasons, the thin reinforcement may become detached and this phenomenon may spread causing the gradual separation of the glass fibre matting from the surface of the slab, thus adversely affecting the functionality of the product.
  • the product undergoes the most varied stresses and as a result of its different capacity of the reinforced slab to withstand the stresses in the two directions described above, breakages and/or cracks may occur, preventing its utilization.
  • a second example of a product known for some time consists of a aluminium cellular (or "honeycomb") panel which is closed on the two opposite surfaces by thin layers (or “skins” in technical jargon) of glass fibre.
  • a thin layer of stone material is applied to one of the two surfaces of the cellular panel, onto the outwer face of the skin.
  • the structure of this cellular panel is very rigid, as is the structure of the composite product formed by the honeycomb panel and the layer of stone material.
  • honeycomb structure as such, which does not provide any support for the fasteners required for vertically fixing the panel to the support structures. Moreover, along the periphery of the panels, the cavities corresponding to the open cells remain exposed, thus requiring a finishing operation for some utilizations of the product.
  • the object of the present invention is to provide a panel which does not have the drawbacks mentioned above, which is thin and therefore light but, at the same time, withstands adequately (i.e. without breakages which prevent practical use thereof) the stresses in both directions to which it is subject during the various processing steps and during the handling deriving from its use, which is also not affected by peeling and which has along the whole of its perimeter a full-thickness uninterrupted rib.
  • a composite panel of the above mentioned type namely a thin panel comprising a slab of stone material combined with a reinforcing element, characterized in that said reinforcing element consists of an unbreakable structural sheet of reinforced resin which is formed by bundles of non-twisted single-filament fibres embedded in a hardenable resin, said structural sheet of fiber reinforced resin being formed separately so as to combined, once hardened, with the slab of natural stone and/or agglomerate material and/or sheet of ceramic material.
  • fiber reinforced resin sheets is understood as meaning sheets manufactured using inorganic fibres of a varying nature such as glass fibre, carbon fibre, Kevlar fibre, basalt fibre, aramide fibre or other types of fibres, the common features of said fibres being that they are non-twisted, single-filament and interwoven in the form of matting and that they are to be used in one or more mats of varying weight arranged one on top of the other.
  • the wording "impregnated with resin” is understood as indicating that the sheets are manufactured by impregnating the fibres with structural resins such as polyester resin, epoxy resin, acrylic resin, pol urethane resin or other resins.
  • structural resins such as polyester resin, epoxy resin, acrylic resin, pol urethane resin or other resins.
  • the stone material element of the panel has a considerable thickness compared to the thin fibreglass layer which acts as a reinforcement when the load is applied on the side where the stone material is situated.
  • the slab of stone material is not required to contribute to the mechanical strength thereof since the fiber reinforced resin sheet always has a thickness and a rigidity sufficient for ensuring as such that the thin composite panel has the necessary rigidity and robustness.
  • the fiber reinforced resin sheet has a high capacity to withstand any type of stress to which it is subjected and, in particular, owing to its rigidity, resists equally well both stresses which flex it in one direction and stresses which flex it in the opposite direction.
  • the thin composite panel thus obtained has excellent stress-resistant characteristics. In particular these characteristics are exhibited also in the case where the forces are applied such as to bend the thin composite panel with the convexity directed on the side where the stone material is situated, namely in the case where said stone material is subject to a tensile stress, as will be explained more clearly below.
  • the thickness and the rigidity of the fiber reinforced resin sheet which is combined with the slab of stone material are such as to prevent the possibility of peeling since both the combined elements are rigid and remain constantly parallel with each other along the joining line of the said slab and of the said sheet.
  • FIG. 1 shows a cross-section of a composite panel according to the present invention
  • Figure 2 shows a partially sectioned plan view of the composite panel according to Figure 1;
  • FIG. 3 shows a partial cross-section through the structural fiber reinforced resin sheet of the panel according to Figure 1;
  • Figures 4 and 5 show a sectional view of thin composite panels with different thickness ratios, compared to Figure 1, of the slab of stone material and the structural fiber reinforced resin sheet.
  • reference numeral 10 denotes overall a composite panel comprising a slab of stone material 12 combined with a sheet of fiber reinforced resin 14.
  • the slab of stone material 12 consists of natural stone material such as, for example, granite, marble and travertine, alabaster, slate, porphyry and the like.
  • the slab may be an agglomerate of stone material or of ceramic material, such as those described in Italian patent Nos. 1,056,388, 1,117,346 and European patent No. 0,378,275 in the name of the same applicant (to which reference should be made for further details) and distributed under the trade names Bretonstone and Lapitech.
  • the fiber reinforced resin sheet 14 as can be noted more clearly from Figures 2 and 3, consists of a matrix 15 made in a hardenable structural resin embedding bundles of single- filament fibres 16 which are non-twisted and interwoven in the form of matting 18. In the embodiment shown in Figures 2 and 3 there are four mats which are arranged one on top of the other. In a fiber reinforced resin sheet 14, the quantity in weight terms of the single- filament fibres 16 must be equivalent at least to 50%. '
  • the resin preferably used for the manufacture of the structural sheets is polyester resin which is suitable for the purpose and low-cost. It is also possible to use other structural resins, such as those above mentioned, with appropriate characteristics.
  • the fiber reinforced resin sheet is combined with the slab of stone material when the catalysis reaction of the resin has taken place, so that the structural sheet of fibreglass has hardened and achieved its dimensional stability.
  • non-twisted single- filament fibres impregnated with polyester resin are preferably used since the linear heat expansion coefficient of these sheets after hardening, - when the preferred fibre/resin volumetric ratio of about 65/35 is observed - is much the same as that of the slab of stone material, namely about 8-12 x 10 "6 .
  • the reinforcing fibres used in the resin sheets may also be of another type, such as, for example, carbon fibres, aramide (Kevlar) fibres, basalt fibres or the like, provided that the structural sheet of fiber reinforced resins manufactured with these types of fibres other than glass fibres assume values of linear heat expansion coefficient which are similar to those of the conventional sheets glass fiber sheets which have been described above.
  • the thin composite panel according to the present invention is formed by two elements, namely a structural part consisting of single-filament fibre, in particular glass fibre impregnated with polyester resin, and a lining part consisting of stone material, each of the two elements having its own characteristics as regards both deformability and resistance to compressive/tensile stresses, which in turn depend on the nature of the material, the elastic modulus and other non-intrinsic parameters such as, for example, the thickness.
  • this panel After their manufacturing process and until the final installation, this panel is mainly subject to flexural stresses which produce a tensile stress in the streched part of the cross- section and a compressive stress in the compressed part of the same. For as long as these stresses remain below the respective maximum affordable loads - namely a loaid below the ultimate tensile strength in the streched part of the cross-section, the composite panel withstands the flexural stresses to which it is subject.
  • the composite panels according to the present invention were instead found not to suffer from such a limitation, to the extent that the maximum stress corresponds to the maximum tensile strength of the fiber reinforced resin sheet.
  • the composite panels according to the present invention are able to withstand flexural stresses which stretch the part of the cross- section made with stone material beyond its ultimate tensile strength without affecting the integrity and functionality of the composite panel.
  • the effect of a very high stress, beyond the corresponding ultimate tensile strength, in the part made with stone material of the composite panel is the generation of microscopic fissures in the stone material such that the same is relieved of the stress exerted on it by the fiber reinforced resin sheet which is easily able to withstand a a big tensile load.
  • the said microscopic "additional" fissures do not affect the quality and the solidity of the thin composite panel to a greater degree than the larger or smaller fissures which naturally do already exist in the stone material before it is applied onto the fiber reinforced resin sheet.
  • a composite panel In daily practice a composite panel has for example to withstand stresses which arise during the manufacturing process and the subsequent transportation and installation steps, including the situations where it is the slab of stone material to be subjected to tensile stresses.
  • the fiber reinforced resin sheet In order to perform such a function, the fiber reinforced resin sheet must therefore have an intrinsic rigidity and strength which is at least sufficient to withstand the stresses resulting from the panel own weight.
  • the thickness of the fiber reinforced resin sheet must vary depending on the overall thickness and weight of the composite panel. With regard to its physical and mechanical properties, it was possible to establish that the preferred thickness of the fiber reinforced resin sheet should correspond to 45% of the overall thickness of the composite panel, apart from the thickness (in the region of 0.6 mm) of the thin layer joining together the two sheets which form said panel. Taking a composite panel with an overall thickness of 7.6 mm as an example for the above given definition of the term "thin panel”, on the basis of the preferred ratio between the overall thickness of the composite panel and the thickness of the structural fiber reinforced resin sheet, the latter will have a thickness of 2.80 mm [i. e. (7.6 - 0.6) x 0.40], while the slab of stone material will have a thickness of 4.20 mm.
  • a thin composite panel on the other hand, with a thickness of 10.6 mm should be composed of me joining layer (0.6 mm thickness), a slab of stone material with a thickness of 6 mm and a fiber reinforced resin sheet with a thickness of 4 mm.
  • a fiber reinforced resin sheet formed by bundles of non-twisted single-filament glass fibres interwoven in the form of a matting and polyester resin is approximately composed, in terms of volume parts, of 53% fibre and 47% resin; since the specific density of the resin is about 1.12 and the density of the fibres is about 2.35, the resulting weight ratio glass/resin is about 70/30.
  • step 3 Applying, onto each of the two opposite faces of the slab of stone material (as obtained in step 2), one layer or mat of non-twisted single-filament glass fibres, impregnated with resin, said layer or mat being intended to form the adhesive element for joining a fiber reinforced resin sheet (as obtained in step 1) to one of the two faces of the stone slab (as obtained in step 2);
  • step 4 Applying a fiber reinforced resin sheet onto each of the two surfaces of each one of the above mentioned slabs of stone material (as obtained in step 2), thus obtaining a semi- finished product where the adhesive layers or mats obtained in step 3 are located between the fiber reinforced resin sheets and the stone material (step 2);
  • step 4 Sawing the semi-finished product obtained in step 4 along the mid plane of its cross-sectio so as to realize two thin composite panels therefrom as final products.
  • step 1 the fiber reinforced resin sheet
  • one or more mats are deposited in a flat form which are made with glass fibre having the characteristics indicated hitherto and an unit weight suitable for the manufacture of composite sheets with the desired final thickness.
  • a quantity of about 430 g of polyester resin for about each 1000 g of glass fiber is poured and spread over the mats and, by means of a suitably rolling action, the resin is made to impregnate the mats uniformly, thus obtaining a green sheet of fiber reinforced resin sheet.
  • Said green sheet is hardened, in accordance with known techniques, by means of either a cold-catalysis or hot-catalysis process of the impregnating resin.
  • one green mat or layer of glass fibre, with a weight for example of 500 g/m 2 , impregnated with epoxy resin, is applied onto the faces of the slab of stone material (as obtained in step 2) so that any unevenness present in the surfaces of the slab of stone material and the fiber reinforced resin sheet is mutually offset.
  • the said mat or layer of glass fiber for joining together the fiber reinforced resin sheet and the slab of stone material will have an average thickness of about 0.6 mm.
  • the surface of the stone slab must be cleaned and dried before the matting is applied onto it, said matting being subsequently impregnated on the said slab by means of a rolling operation.
  • epoxy resins shall be used which, during hardening, undergo a negligible retraction.
  • step 5 namely the subdivision of the slabs (obtained from sawing a stone block and treated as described in step 4) into two panels, it is possible to use conventional frames suitably equipped with special slab-carrying carriages.
  • a suitable apparatus is described in the Italian Utility model application No. TV2000U000030 filed on 21.7.2000 in the name of the Dario Toncelli.
  • the manufacture of a thin composite panel according to the present invention may also be obtained in other ways.
  • the panel may be obtained by combining the fiber reinforced resin sheet with a slab of stone material already sawn to the desired thickness or reduced to the desired thickness by means of a mechanical sizing and/or smoothing step.
  • the said slabs will have the desired thickness and will each be combined with a single fiber reinforced resin sheet in order to obtain the panel.
  • a fiber reinforced resin sheet might be of 4 mm thickness and a slab of stone material of 3 mm with a resulting fibreglass/overall panel thickness ratio of 4:7, not considering the thickness of the joining layer (see Figure 1).
  • the fiber reinforced resin sheet might have in specific applications the same thickness as the slab of stone material with a resulting fibreglass/overall panel thickness ratio of 1 :2, relative to the overall thickness of the panel, not considering the thickness of the joining layer.
  • Figure 4 shows on the other hand an examplary panel in which the thickness of the fibreglass layer is less than the thickness of the slab of stone material.
  • the joining line between the fiber reinforced resin sheet and the slab of stone material is rather close to the neutral axis of the cross-section of the composite panel and consequently is only subjected to a low stress.
  • a thin composite panel according to the invention can have a price on the installation site that, in several applications, can compete with that of a conventional slab of stone material and this is even more true in case of a high value stone material.
  • a thin composite panel with a thickness of 7.6 mm has a weight of about 16.5 kg/m 2
  • a stone slab with a thickness of 2 cm weighs about 54 kg/m 2 .
