<p>- 13 Abstract The present disclosure provides a building panel that comprises a core of a material that has a compressive 5 strength that is substantially the same or less than its tensile strength. Further, the building panel has first and second external layers arranged on respective first and second sides of the core. The first and second external layers comprise a material that has a greater 10 tensile strength than the tensile strength of the core material. At least one of the first and second external layers comprises at least one ribbing structure that may be internal and is arranged to provide structural support for the building panel. 69356401 (GHMatters) P97900.AU.2 JMEAD 24/09/15</p> |
