Definitions

  • the present invention relates to composite panels such as composite building panels and a method of building the composite panels.
  • the composite panels may include but not be limited to facade panels, floor panels and wall panels used in the building industry.
  • composite panels are used for external walls, facades and even floor installations.
  • composite panels can exhibit many advantageous features such as being weather proof, noise absorbing, fireproof, light and easy to cut, impact resistant and easy to maintain.
  • construction panels such as fagade panels and floor panels must comply with strict building code regulations for fire resistance. Accordingly, there is a need for providing composite building panels with improved fire-resistance properties.
  • the invention comprises a composite panel comprising:
  • the invention comprises a composite panel comprising: a moulded core having at least 30wt% magnesium oxide; and two spaced apart outer sheets for positioning the core therebetween;
  • each of said outer sheet is adhesively bonded to the moulded core.
  • the moulded core comprises at least one reinforcing mesh of a first type positioned in an interior portion of the moulded core.
  • the moulded core further comprises at least one additional reinforcing mesh of a second type positioned in a spaced relationship relative to the at least one reinforcing mesh of the first type.
  • the at least one additional reinforcing mesh of the second type is positioned adjacent the outer surface of the moulded core.
  • tensile strength of the reinforcing mesh of the first type is different from tensile strength of the reinforcing mesh of the second type.
  • tensile strength of the reinforcing mesh of the second type is lower relative to tensile strength of the reinforcing mesh of the first type.
