| 20110056161 | EXTRUDED GEOPOLYMER FRAME PROFILES FOR WINDOWS OR DOORS - This invention discloses frame profiles for building elements such as windows manufactured by the extrusion or pultrusion of fibre reinforced geopolymer. Extrusion advantageously aligns reinforcement fibres enhancing strength in a single direction. One embodiment of this invention uses cellulosic reinforcement fibre which advantageously chemically bonds to the geopolymer molecules and provides an extremely tough and strong product. The embodied energy in the cellulosic fibre will also be significantly lower than most alternative reinforcement materials. | 03-10-2011 |
