Definitions

  • the present invention relates to a composite structural panel, with a honeycomb cellular structure, containing a filling material designed to give at least thermal resistance, acoustic resistance and fire resistance properties.
  • the invention also relates to a method for production of the panel .
  • the technology for construction of composite structural panels already includes light panels for structural and covering purposes, produced with an aluminium inner honeycomb structure; panels designed for specific uses in the aviation and space sector, but more recently also used in sectors other than the sector of origin.
  • Such panels basically comprise a thin aluminium honeycomb central core, on the opposite faces of which plastic resins are used to glue thin aluminium sheets, or layers of fabric or even plastic laminates.
  • Such panels have very high levels of stiffness and planarity relative to their mass.
  • the density of such panels - due to the presence of a central core with empty cell structure - is very low, being between 30 and 80 kg/m 3 .
  • the panels also have very disadvantageous thermal insulation, acoustic insulation and fire resistance properties, which greatly limit their possibilities for use in application sectors other than those for which said panels were originally designed.
  • the above-mentioned negative properties are further aggravated by the reduced thermic inertia and acoustic mass possessed by such panels, to which one must also add a high capacity for emitting black smoke in the event of a fire.
  • Further application limits for said panels are also represented by some poor mechanical and structural properties, which may be attributed for example to: their relatively low load- bearing capacity; a limited capacity for withstanding pressure and/or vacuum loads,- a limited resistance to peeling or, more generally, abrasive actions on their surfaces.
  • the aim of the present invention is therefore to overcome the above-mentioned disadvantages with a composite structural panel which, although maintaining a basic structure that can be traced back to a prior art type, is able to extend the spectrum of intrinsic features of such a basic type, to combine them in various ways and to modulate them quantitatively depending on the specific requirements of the possible and different intended application sectors .
  • the invention also has for an aim to provide a method for production of the above-mentioned panel.
  • Figure 2 is an exploded perspective view of the panel of Figure 1;
  • Figure 3 is a side view of a possible alternative embodiment of the panel illustrated in the previous figures;
  • Figures 4a - 4f are diagrams of the steps of a first method for production of the panel of Figure 1;
  • Figure 5 is an exploded view of the panel of Figure 1 illustrated in a characteristic forming step belonging to an alternative method of production;
  • Figure 6 is a cross-section of a detail of the panel obtained using the alternative method illustrated in Figure 5.
  • the numeral 1 denotes as a whole a composite structural panel, basically comprising a three-dimensional stratiform element 2 with a honeycomb structure, having a plurality of open cells 3 arranged in an orderly fashion, containing a filling material 4.
  • the panel 1 also includes two covering sheets 5, glued to the three-dimensional stratiform element 2, substantially forming two opposite faces of the panel 1.
  • the panel 1 generally has a density which may substantially vary between 30 and 1500 kg/m 3 , depending on the materials used and the performance properties required of the panel 1 by the applications for which it is intended; properties which by way of example, but without limiting the scope of the invention, include: thermal resistance; acoustic resistance; and fire resistance, considered both individually and in various combinations and if necessary also with other additional performance properties.
  • the filling material 4 may be obtained in various structural forms, in particular concerning the state of aggregation of the material, and the physical/chemical compositions.
  • the filling material 4 may include: mineral aggregates expanded, agglomerated, or in the loose state; vegetable fibres; and/or amorphous silicate resins mixed with expanding agents, which are inserted in the cells
  • the filling material 4 may also be obtained using thermally expanded insulators, chosen from the families of phenolic resins, polyurethane resins, acrylic resins or polyester resins.
  • the filling material may also include expanded mineral mixtures .
  • Said covering layer 6, which can be applied to the outside of the panel 1 is designed to give the panel 1 a specific surface finish, or is even designed to give it structural and mass properties particularly useful in allowing the panel 1, for example, to have a specific inertia to some physical phenomena involved in construction or in the architectural field.
  • the panel 1 may advantageously include in its structure such a covering layer 6 which may consist of a layer of plaster; a stone material, such a marble or granite; a ceramic material; a vitreous material; a metal laminate; or even a plastic material (for example phenolic) .
  • a covering layer 6 which may consist of a layer of plaster; a stone material, such a marble or granite; a ceramic material; a vitreous material; a metal laminate; or even a plastic material (for example phenolic) .
  • the panel 1 may have technical features which allow additional advantages in terms of the capacity to withstand weather, the abrasive effects of dusts carried by the wind and/or even a chemical attack ascribable for example to the acidity of meteoric water.
  • the materials used to make the three-dimensional stratiform element 2 may be metals, such as aluminium and/or steel alloys; or even fibreglass and/or carbon fibre materials. However, it should be noticed that the three-dimensional stratiform element 2 may also be made from a chequered plate or even a net whose mesh forms the above-mentioned cells 3.
  • Figures 4a - 4f may be used to describe a method for production of a panel 1, as described above, in which the material 4 which will be used to fill the cells 3 is in a loose solid state. Said method basically comprises the steps of :
  • Figures 5 and 6 may be used to describe an alternative method of production for a panel 1 as described above, an alternative particularly advantageous in cases in which a preformed panel of filling material 4 is to be used, for example a panel of relatively friable solid material.
  • the method basically comprises the steps of:
  • This step may comprise simple cleaning to remove even the smallest particles, which could prevent effective gluing of the second sheet 5 which must cover the entire outline of the edges 8 of the cells
